 Re: Just a silly idea.. How about converting some game..

EOTB isn't the game people think it is, a Dungeon Master clone... The dungeons are set out like puzzles rather than it being a grand dungeon adventure and life simulator which DM is. EOTB has very little going on from a technical point of view. The art direction of the C64 version is very cool tho.

I wote for "There is no game: Wrong Dimension"

Of course, not the whole game. Just taking the idea. I love this game.

Or "Inscryption" It's a very good game. I played out that maybe sixteen-seventeen times.

 Re: Just a silly idea.. How about converting some game..

@rksoft.. I *love* your mockups. Question though. How are the colors laid out? Are the screens supposed to be multicolor hires (so 4 colors per tile) or regular multicolor tiles. Would love to pick your brain about some of them as I'm working on custom hardware similar to the +4/c16

 Re: Just a silly idea.. How about converting some game..

@RKsoft I ADORE your mock-ups! Burger Time, Super Mikey Bros, Pitfall, Mario Bros, Giana Sisters, Donkey Kong, all so fabulous, colorful and funny! They really reminded me of why I started liking games in the first place. These should all be made to their own ports really. happy

Alongside Pets Rescue they've really sparked my interest for the Plus 4 / C16 and the wish to create some small games of my own for the Plus 4.

@Mad Thanks so much for sharing Plus4Studio These kind of tools are really invaluable for development.

 Re: Just a silly idea.. How about converting some game..

Luca I completely hijacked the thread.
I hate it when people do that and went and did it myself :-/ Awkward.

Anyway back to the original thread.

Has anyone converted Kennedy Approach? Used to love that, on the C64 so much so I converted it to Gameboy (well the main game engine).

The other one I would love to do is paradroid, but I don't think I've got the 264 kills at the moment (or the time).

And now, let's go incredibly back to the real initial topic of this thread: converting games to Plus/4.

Retroworks has a large catalogue of Zilog based games of various genres they used both to sell and to offer as freeware. And the source code is available too. I played the lovely Zelda-ish "Los amores de Brunilda" and I found it quite playable with a fascinating story.

 Re: Just a silly idea.. How about converting some game..

Stinaris I looked at the ghost n goblins disc and it contains 3 files. If you ask me I would follow Bubis advice to use their fastloader. It occupies the memory from $200 to $400 (in our case), which is pretty good. You even have a very good decrunch routine in there, even if you have to patch the code (injecting the propper address containing the data to decrunch) to use it from outside. The loading takes just some eyeblinks in time, if you ask me :)..

Anyways, nice game you showed up there! happy

 Re: Just a silly idea.. How about converting some game..

Because I've had a tricky time getting stuff into 16K, I thought I'd try converting something that was originally 16K.
So this weekend I wrote the main game engine for the Spectrum 16K game Transvision.
Here is where i am thus far (yes I know the sound is awful)

https://vimeo.com/259140635

This game with 10 levels occupies 8.5K including the character set (127 characters), colour and character screen.

There is no title page, character death, music or game over screen. But that should all fit in 1K easily (unless I get a bit fancy with the title page)

Obviously there are no animation frames as such and each character is only 1 char.

I'm really starting to wonder how the author of Ghosts'n Goblins got as much as he managed to into the machine!

 Re: Just a silly idea.. How about converting some game..

After the release of that fantastic new game it becom every evident, that with 64K RAM the 264 platform is a killer. happy
(OK there will be always a need for a hw sprite and quadro SID sound happy )

Actually C= could realese C16 and C116 with 16K and some empty RAM IC sockets plus a jumper, and with the help of few 41464 you could have a 64K machine easily. Instead you have to solder the board and add new wires on the bottom of the board (maybe cut one lines too?). It is a kind of crazy
While for VIC-20 they had tons of C= cartridges, and they could sell a lot for a good money.
C= even did not release an official RAM 64K expansion card with a pass-though expansion port to have some circuit diagrams...

 Re: Just a silly idea.. How about converting some game..

I totally agree that the C16 should have been the C32. That would have allowed infinitely better games.
At least then yo could run a bit map screen and draw software sprites onto that rather than pre storing char sets.
I'm also confused why, as a replacement for the VIC20, it only had 2 channel sound? Weird.

 Re: Just a silly idea.. How about converting some game..

I had a plus-4 and could only play C16 games and I’m interested to see how much of a limitation it places on the programmer.
As it happens, a great deal. I grew up with a C64 and the sprite and memory make it a joy to use.
But I really need to do this in 16K.

This is also a step to writing something for the Atari 2600. You think a C16 is limited, the 2600 is laughable.

I love finding ways to overcome the limitations. For example, to keep the soft sprites fast I place each line of the sprite 40 characters on from the last. I do this because I can reuse the same register without reloading it to handle the index.

 Re: Just a silly idea.. How about converting some game..

OFF/remark (as you wish)
sorry to be a little negative, but fitting the game into 16K is not a really good idea (if I understood well).
You have to leave out graphics, effect, maps to fit into the 16K.
(Please consider, how much better the 48K ZX Spectrum games to 16K versions)

I think back in the day the platform suffered a lot due to fact, that every company transferred chopped down lame 16K conversions, like Ghost and Goblins (OK, there was a programming bug, hires VS multi characters).
And Commodore made a failure by releasing C16 and C116 with 16K, they should came with 32K (or make the memory expansion much easier and more straighforwards, like C128's VDC's 64K expansion...)

I had C16 too when I was a kid, but I upgraded the memory to 64K as fast my parents could pay it ( happy ).
Without 64K, this computer is really, really limited and cannot show it's real potentials (and that1s why the gamers all left the platform, because there were very few impressive games due to limited RAM).

 Re: Just a silly idea.. How about converting some game..

Hi Stinaris,

just read your post. Nice move to port Delta to the C16. The idea with keeping the "sprites" distant to each other is marvelous. I hope you get this final. About RKSofts mockups: I think he does them preferably for Basic games. But that's just guessing here. There real soft sprites almost aren't possible. Perhaps with your trick of using preshifted tiles, that would be doable, too in Basic. I hope atleast one level of your Delta clone will see the daylight somewhen, hard enough that XeO3 didn't got finished, yet. Major props and respect to you for doing this in 16k!

 Re: Just a silly idea.. How about converting some game..

Hi Rksoft,

The Mario mock up shows a Mario character with 5 colours (background black, beige, white, green, brown). Already colour clash issues if he jumps. you've got it adjacent to a block consisting of background black, white, beige and blue. Which simply cannot happen on 264 hardware, as far as I'm aware, without major colour clashing issues.

 Re: Just a silly idea.. How about converting some game..

Hi Mad,

Moving by character blocks isn't really for the game type. I'm basically trying to convert C64 Delta to the C16.
Obviously the main ship can't be spinning, it would take the entire memory to animate happy
With careful planning and cunning I think I can get something reasonable. I would like a proper soft Sprite for the main ship and keep the attacking ships at least one whole char away from each other. This will give the illusion that everything is a Sprite.

I've got a nice scrolling frame for the top and bottom of the play area (a bit like delta) but it's a lot slimmer because Delta puts sprites in the border!.

Not worked on it for a bit as I'm trying to convert the music at the moment and building some tools to help.

 Re: Just a silly idea.. How about converting some game..

Hey Stinaris,
i don't know what mock-up you mean because all of them have a black background. So the softsprite will have 2 fixed colors (multicolor #1 and #2), the char color and the black background color (for the eyes as example).

Only my Giana mock-up isn't conform because the softsprites uses all 3 colors but it will have color clashes when collides with a background tile like the bush. It can be fixed by using only 2 colors and the 3. charcolor is for the overlapping!

But:
The little secret is to use the right order of colors for your tiles and sprites. All my mock-ups can be use in BASIC games! If you want, i can make a little BASIC program that shows a mock-up on your screen (or emulator). If you want, let me know what mock-up. wink

 Re: Just a silly idea.. How about converting some game..

Hey Stinaris, just some side notices. I think there is no easy way around the limited softsprite capability. You mentioned using Rasters to color the screen differently [horizontal bands]. I think that is an good option to increase the colors usable per screen or sprite.


I think the main thinking about this sprite/color thingy is, were you want more colors. Behind the sprites or in the sprites itself.

First option is: Using more colors for the sprites itself. So you can use the 3 fixed colors for the background behind the sprites. You can color everything solid which can never be behind the sprites with more colors, though. This approach could produce color clashes when sprites "collide".

The second is: To use only the 3 fixed ones for your sprites and color all the background like you like to. The drawback is, that you just have relatively monochrome sprites then. However the color of sprites gets easily "removed" by the brain you don't feel a big difference by it when playing. You even can change the 3 fixed sprite colors on the fly, let's say at a level or region change, and the player wouldn't get angry by this (at least that's how it behaves for me).

The third option is: To just move by chars and not by pixels. An FLI mode for instance could make you use a 40x50 screen for it, which is slower in using it then, too.


If you use a bitmap mode, you have 2 fixed and 2 free colors per cell/tile which could change the approaches you can use slightly.

There are some more advanced techniques to combine the colors so that you do have color clashes but they aren't recognizable. Degauss is said to have produced a demo of such a mode in the past. I know this is not helpful, but as said there is no easy way around this color clash issue. If anyone has ideas about it, I would be also glad to hear them here.. happy

This is just what I "discovered" over time, and most probably not helpful..

So let's wait for RKSoft to explain if he found a way around this happy.. Could be that it's just the crossplatform editor he uses.

 Re: Just a silly idea.. How about converting some game..

RKSoft, can you post videos of you mock ups in 264 basic because I would really like to know how you can get so many colours on screen and have zero clash between sprites with different colours. In particular when they are adjacent on screen.

It's the biggest pain I'm having. I can solve it, partly and in terms of increased colours, but I cheat by using horizontal bands , on horizontally scrolling games. But it takes a lot of planning to avoid clash and very limited palettes. This really makes the whole 121 colours a bit of a joke in reality ( for games at least).

I can now see why no one bothers with 16k versions as defining software sprites is so memory intensive as 12k really isn't very much (16k - 1k screen - 1k colour - 2k character set)

 Re: Just a silly idea.. How about converting some game..

Yeah, sure, the software mouse cursors (Borrowed time, Tass times) are also made with two fixed colors.

I know our limitation, on the other hand I started to prefer Spectrum approach instead of a speudo C64 sprites approach, as the C64 sprites color are typically VERY different from the background, but we just can't do it. Doing it will be a great challange and fun, but I can foresee, it will be very hard to play due to bad visibility on the colorful background. (eg. notice knifes and prevent them)

Recently checking AIT I realized it does not use sprites (I tought it did), but overwrites those few background images. But it is almost not visible side effect, because the majority of the background is black, and the movement is so fast. As the sprite has so different color than ANY of the background objects, it is always easy to recognise your hero. I prefer this way.
Eg. Bubble Bobble on Amiga or Atari ST may work with exactly the same way, and those are still great games, despite they do not have those colorful background images the arcade version has.

But I am not a programmer, just a hobbist hobbit grin

I'm with Csabo, I like all mockups, but the very interesting ones include the real deal about colours involved in a realistic project eventually working on the original machine.
Hafta say, for what I know, KiCHY uses to automatically considers all the variables in his own mockups, they refers to a real machine and they're thought in order to include sprites. I loved his Green Beret mockups right because, counting the colours involved and their usage, I see it's possible to build some sprites on it, see the 3 fixed colours? wink

Dig Dug is easy to make them look a like my mock-up. I can make a little testgame in BASIC to show you. Giana Sisters is hard because the color clashes with the background (bushes). But i can change some things to handle with it. When it works in BASIC then in machine language too.

 Re: Just a silly idea.. How about converting some game..

Since I didn't write anything here for a long time.

At first glance we tried to convert some game. Like the thread said, I was searching for a propper game to be converted. They all seemed very good. My favourites (from a link) were Space Harrier, Lemmings and Super Mario Bros. I thought that Lemmings is too hard of a task. Remember these 127 levels (as far as I remember). So we choose Super Mario Bros..

However we stopped that project, because Nintendo would have crashed it anyways. They have a big lawyer bunch and are very hostile at even the slightest corruptions of their copyrighted material. (You find a lot of information about this in the net).

However we currently slowly get build up another own and original game. It will take some months now, but I think that will turn out well.

Sorry that we didn't convert a game, as it was originally planned..

Everyone who wants to put good candidates in this thread is very welcome as always but I don't know if someone could build these conversions. Anyways good to have this thread (I hope).

And RKSoft gives this thread another meaning by posting his prebuilt graphic sets. So programmers also already have a graphician if they choose to do such a task. (Thanks from here, too for this good initiative!)

 Re: Just a silly idea.. How about converting some game..

Another one not out on many systems:
Ant Attack (aka Ant Attack 3D), on Spectrum and C64 only, published by Quicksilva.

No smooth scrolling, though it might be nice to have in a conversion. Also mono graphics, with shading to show perspective. Suggestions for improvement: a map editor.

This game had a Spectrum-only sequel: Zombie Zombie. Could be nice to have a conversion of this to another system.

 Re: Just a silly idea.. How about converting some game..

I just thought of a few more games that should / might be possible on the 264 series.

River Raid - while available on many other 8-bit systems, it would be new to the 16/plus 4.
River Raid 2- the sequel was only available on the Atari VCS.
Chopper Command - also only available on the Atari VCS, a Defender-like horizontal scrolling shooter.
The Dreadnaught Factor - Intellivision originally, then Atari 8-bit & Atari 5200. A vertical scrolling shooter, but doesn't rely on fast scrolling.

 Re: Just a silly idea.. How about converting some game..

@siz, tilt, mms: Pinball Dreams is eventually possible in bitmapmode. Scrolldistance per frame should be 8 or below. I think the physics is not the hardest part it's "just" physics. There is an Amstrad CPC conversion going on right now. The biggest problem of them is the memory. And I think they use 128k. I think a complete and animated table will not fit in 64k. The C64 conversion was stopped because of memory as far as I know. There are a lot of tunes also used at every table.

 Re: Just a silly idea.. How about converting some game..

I was thinking about a pinball game lately. Perhaps the fast bitmap scrolling method used in Majesty Of Sprites could be utilized for that but I'm not sure, I'm not familiar with that effect enough to see it's limitations.

Pinball Fantasies is an ace game and I love Stones'n Bones but yeah, I was thinking more Pinball Dreams with that more basic style of table design.

The hardest thing would be to nail the ball physics I believe. If Pinball Fantasies/Dreams ball physics could be replicated with that addictive one more go game play then the Plus4 could be onto a winner. wink

 Re: Just a silly idea.. How about converting some game..

Yeah, my little daughter played with Amiga Pinball Fantasies, and really liked it.
But that very fast scolling of sevelar screens up and own, eh.
With multicolor charset maybe possible, but then only 1 free color per attribute left (VS 2 of the multicolor GFX mode), so may need to give up the nice screens.
FLI would change the end ruesult, but I am not aware of such fast FLI gfx moving routine.

 Re: Just a silly idea.. How about converting some game..

I think you mean the color clashes when Giana collides a background item like bush. I made this as a mock-up. But if anybody wants to use it to make a port i can rework the charset:

- changing the mc1 from dark brown to white
- fix all chars (ie: the dark brown parts to a dark yellow at the stones or ground)

I think this is possible...

 Re: Just a silly idea.. How about converting some game..

After a break, here is my new mock-up for Commodore 264. I tried my best to convert all tiles and enemies but i did not have enough free chars. My set uses 256 chars (2kbyte). To complete it with all charsprites, you need to mirror the charsprites via code or use 2 charsets (8kbyte) and switching ingame.

Have fun... and you can download the files from my webpage.



For the first 2 levels, you can take a look at my webpage. I converted them happy.

 Re: Just a silly idea.. How about converting some game..

Cool games (Nintendo most probably didn't recognize them). However I would change the name for our game to a better sounding one. Perhaps Ultra Mikey already would do the trick, but I would apreciate any suggestions!

We change at the moment the whole game to better fit into a original production. It will be more like a giana sisters for the 264 then. However it will be a cooler game! We currently working on a Tiled editable version. The editor Tiled can be found on www.mapeditor.org. One really important point is to also have our own levels instead of the original ones. As I read most of the content is copyrighted including levels, characters and music. However it is ok to use our own adaption of the tile graphics since they are different anyways!

 Re: Just a silly idea.. How about converting some game..

I know that Nintendo kicks freeware projects includes their characters. I worked on a Super Mario fangame 2001 called Super Mario World under the label of BB Software. Take a look at DIV-Arena ... There, you can find another Nintendo remake by my, Donkey Kong.

2002, Nintendo contacted my ISP to remove all copyright content of their games/franchises. Under this, i must removed Donkey Kong PC, Mario Bros. and Super Mario World from my webpage (bbsoftware.net).

So, when i remake fungames with big N arts, so i change name and use fanmade custom sprite/tilesets in my games. Take a look at my tutorial Jumpman, where i use custom sprites and tiles.

Well, if we want to re-made a port to Commodore 264, we should use different name and custom sprites and tiles ...

For the DIV DX development, currently, i work on DIV Kong instead of Donkey Kong. The copyright is by me! wink

 Re: Just a silly idea.. How about converting some game..

Ideas (such as gameplay) cannot be copyrighted. Your game doesn't use the copyrighted Mario characters, or any of the likenesses they protect, or even music.

Do they give a damn about a Commodore game? If that game has their copyrighted material, reality says yes. Simply Google terms like company name + cease and desist. I could give you a bunch of links to fan projects they shut down, but 1) this stuff isn't fun, 2) those links don't really belong here, 3) you can find them yourself.

It's a given though that if you change the name and the character graphics, you are in the clear to make a clone.

 Re: Just a silly idea.. How about converting some game..

Now i read a lot in the net. We do have no other choice than taking different musics, different characters and different levels (graphic can be kept, just other structures). I also asked a lawyer specialized on this topic, lets see what he'll say. I could ask Nintendo what we shouldn't do but a grant of a Mario imitation is very very unlikely. I already have some ideas for some enemy modifications.

And we need another main character! And name for the game!

I would ask Nintendo directly, if they give permission for a port for a "outdated" 264 system. Maybe they don't have a Problem with it, since we are honering and advertising a classic game.

 Re: Just a silly idea.. How about converting some game..

Hello Super Mikey people!

As suggested by carrion we should change the name to a more not mario like name.. We will be pretty close to the original in many aspects, however perhaps a better name will keep us fine with Nintendo. What do you think about this? And are there any good possible names already?

https://www.mariowiki.com/List_of_Mario_knockoffs_acknowledged_by_Nintendo the section with the fan games is of particular interrest! I think think the main problem is that the assets almost look like mario in most of the cases and that they do reach a big user group..

Perhaps we should atleast use a different main character then, perhaps another name for the game would be sufficing already!

videos of the games kicked from the market (the others are all commercial):
Super Mario Bros X
fullscreen mario
No Mario's Sky
Super Mario Bros. Z
Super Mario ReMaker

what can we do? (despite the fact, that it has no impact or value)

https://www.nintendo.com/corp/legal.jsp#parents

And they sued a youtuber who build Mario and Peach from Minecraft cubes.. The display of the picture is ok they said, but it's not if they are making any money of it!

I think I will talk to a lawyer first :)

 Re: Just a silly idea.. How about converting some game..

For some relatively simple games that I think the systems can handle.

-A nice platformer on several systems, including the VCS: Montezuma's Revenge

-Radar Rat Race (Rally X)
-Omega Race - both had versions on C64 and VIC-20

-Star Castle - I'd previously asked if it was possible, having seen a video of a conversion to the Atari VCS

I agree with those looking for Dig Dug, and Donkey Kong, there being no good version on the C16/+4. Also, how about a better Defender? In fact, it would be great to have accurate versions of all the arcade mainstays. Many are single-screen shooters that don't rely on smooth scrolling (Invaders, Galaxian, Berzerk, Space Firebird, etc). Other non-scrollers such as Q*bert, Pooyan, and Lock 'n' Chase shouldn't be beyond the systems.

And yes, Door Door would be charming addition to the roster of games. I'm sure there must be lots of similar games, less well-known in the west, that would be good conversions.

The fish and goomba have 4 frames, now. The piranha plant and the beetles have 2 frames. Is it okay? Then i add a 4.frames to above called characters.

 Re: Just a silly idea.. How about converting some game..

The problem is it's much better to have a cycle of 4 frames, because that is dividable by 4 and thus easy to handle by the 6502 a "division" by 3 is not possible and you mostly end up with a big mess of special code for every animated sprite. Do you think you are able to make them somehow to a 0,1,2,1 animation or if it doesn't suit you it would also be possible to add a frame so I can use a 0,1,2,3 animation. That would consume more memory, though.. Kichy is more precise in judging game graphics, so I would say he is right at that point.. I think he knows his stuff, and you, too happy!
If all 4 frames are different I would favorize these 4 step animations, because it's also more content!

@Mad
If you say the sprites are okay then i don't touch them. You are the programmer wink. We have only 64KB to use for the game, music etc... or will you make a multiloader? But how KiCHY said, when you use 0,1,2,1 on the main char it loosk terrible. I made the frames in order of 0,1,2,0,1,2 etc. (all sprites btw.).

And yes, some frames a copies in this screenshot because why use another char for that when it is avaible? Many custom chars are copies (see the heads of koopa, mikey, goomba etc.). Or the legs from normal mikey and super mikey, all the same. :)

@RKSoft: you could supply a 4th frame if you think, that's better. I would appreciate a 3 frame 0,1,2,1 animation , though, because of the saved memory.. (You have all the time in the world to do this..) (btw, your fishes alread have these 0,1,2,1 pattern even if it are 4 source frames (some of them are the same))

right, i tested it with frame 0, 1, 2, 1, 0, 1, 2 etc. in in loop. It looks weird. I made 3 frames (0, 1, 2, 0, 1, 2 etc.) for the walk and this looks good.

@Mad
if you need a 4.frame i re-made all them for you to pass the walk and arm animation. With your anim the arms looks good but in combination with the legs terrible.

 Re: Just a silly idea.. How about converting some game..

I can't agree with Mad about those walk animations. The legs and arms are out of rhythm.
The arm has 3 stage: front, middle, back. The legs has 2 stage: open, close.
The correct walking anim is:
1. arm: front, legs: open
2. arm: middle, legs: close
3. arm: back, legs: open
4. arm: middle, legs: close (same as 2.)
It is a simple 3 frame animation, played "ping-pong" (1-2-3-2-1-2-3...)

 Re: Just a silly idea.. How about converting some game..

I read it correctly? No flipped sprites needed because you mirror them in your code? oO Extremly greeeeeaat work. I will remove the left looking sprites and add new one for jumping and dead on main char. A dead animation for the Goomba and Koopa, i can add too.

Okay, my work on sprites:
- add jump anim for Mikey
- add fall anim for Mikey (he looks down at falling)
- add dead anim for Mikey
- add crouch anim for Mikey
- add dead anim for Goomba (like on the originalgame?) - a flat Goomba?
- add dead anim for Koopa (do you want that koopa shields to kick them with?)

Okay, do you want some of the following?
- add hanging anim for Mikey (for the finale movement from the pole)
- add look-up anim for Mikey
- a princess to rescue with 2 frames (stay and loving)
- in the oiriginal, there are hammer bros.. Do you want them? I can try...

RKSoft no hurry, take your time. I will check the new anims in the evening.. Thanx a lot (and they look very cool)!! All the best.. happy

edit: I just implemented the new mario animation. I added a functionality for mirroring the sprites to the engine, so the x flipped versions aren't needed anymore. What I really want to say is, the walking animation is excellent. I played it like this first frame 0, then frame 1, then frame 2 and then frame 1 again. And it looks really awesome! Thanx a lot! (Btw. I think if you jump onto enemies in Mario they remain not moving and flipped in y, must look into the game, but I think these spriteframes are missing. And you can remove all mirrored sprites from the set.)

 Just a silly idea.. How about converting some game..

I just talked with Luca, my idea was to ask some people with a poll, which games they wanted best to be converted to plus/4.

The main aim would be to convert something what was never converted to the plus/4 and best also not to the C64.

So we have a unique port of something to the plus/4. I just thought about conversions from the Arcade, Amiga, Famicon(nes), Super Famicon(snes), Mega Drive (genesis) or anything else..

It could be even Giana Sisters or some other game you know (for giana there is also a amiga port).. However me for myself would exclude ghost n goblins or any already ported game.

Just beeing curious what games come up and how they could be ported..

(I don't have any time free at the moment for coding something, however some ideas need a little pretime to blossom rightly.. And I personally wouldn't do too militaristic or brutal stuff.)..

Let's see perhaps there are some ideas of (Arcade/Amiga..) games never ported to the Plus/4.. And don't expect wonders.. The conversions could be exactly that clumsy like many of the old conversions..

So just an idea. What do you think? (Perhaps later on a poll would be good, too)

(And as said I personally don't have any time at the moment).. Perhaps this is also interesting for other plus/4 people.
