 |  Polish games from 1989-92 dug up after 30+ years
Hi all. I think this is material that maybe Plus4World may be interested about.
In the article on our C64portal.pl (in polish but google translator does decent job) we describe a story of a guy name Sylwester and his productions for C+4.
He developed under the name BKP in years 89-9x. He shared the history with us + some programs he was able to recover. So far we have few BASIC games + 2 assembly language games + ROM files that he made for himself to replace 3-plus-1 with most common tools he used back in the days.
According to author the productions were no published anywhere beside him and his friend. I can't find them on the portal here either.
Anyway, here's the article.
https://c64portal.pl/2021/01/03/odkopane-po-30-latach-gry-i-programy-bkp-na-commodore-plus-4/
Please let me know if this is worth publishing on Plus4World.
We also wait for more releases from him as the tapes were found and the author is going to look for his programs on it.

I created a map for Castle Dance, if anyone wants to play through it. The controls are not the smoothest, but you can see that a lot of effort was put into the game.

Very nice map Csabo, the game really deserves it, thank you! I find several common points between Castle Dance, Swords and their never declared father Robo Knight - a C16 classic I love - and probably both the homebrew games have been designed as acts of love to their moral predecessor.
carrion fantastic interview, could we really expect for hundreds of unseen trained versions as I read? I really hope so! Till yesterday, we had some Polish Basic games, and the great works made by Bohdan R. Rau, today we know there were sparkles of a Plus/4 Polish scene cluster! Waiting for what the author will recover from his tapes, I ask for more infos about the phantom AY music which should play in the background when running Castle Dance: are we talking about a specific hardware addon?

Hey, I'm glad that I could finally show my work to a wider audience Programs may not be of the highest caliber, but in those days we only studied with buddies from one backyard, watching and analyzing other programs.
@Csabo, beautiful job! I didn't have such a map even when I wrote this game: D
@Luca, in order to hear music from the AY-3-8910, you need an external card plugged into the extension port commodore. Unfortunately, the card was not very popular. Its control registers are maintained at $ FD21- $ FD23. Even though the AY sounds worse than the SID, its advantage was the additional two in / out ports, through which I liked to control, e.g. light bulbs. I started writing a tracker for making music and stopped working when I bought the first Amiga ... Lack of time (school) and few AY cards on the market discouraged me from continuing to work on the music program.

BKP happy to see you here!
Who had built up the AY card for Plus/4? Can we have some specs and some pictures of it, in order to include it into our /Hardware page? How many programs did use it?
I'm waiting for what you'll be able to recover from your tapes and D64s, trained games included.

When I have some free time, I will take some photos and maybe even find a diagram somewhere
The card was constructed by an elekrtonik and programmer from Poland, Tadeusz Z. (TZ) You must know a program like Copy System - it's the same programmer (Copy System +4)
Unfortunately, I do not have any programs written by other users because I bought the card as one of the first (No. 003). I had to program everything myself. I do not know how many of these cards have been sold and if anyone else wrote anything on AY for C + 4/16.

Glad to hear from you (Please email me or Luca if you'd like a password set up - since we already created an account for you.)
I like Castle Dance, it captured my imagination In the program, this text can be found: "CRACKED & COPY BY METALLIC /FMJ INC." Any idea who that is or how it got there?

Hahaha, "CRACKED & COPY BY METALLIC / FMJ INC." - my friend left it, after breaking security We learned to program in the backyard by creating various security measures or algorithms that were faster or shorter. I showed him your map today, it is he who designed the rooms - he likes it very much
PS. You made a detour to Castle Dance very quickly The one with inviolability makes it impossible to go further in some chambers - it is not possible to lose your life to find yourself at the entrance point to the chamber again

2021 couldn't start better than this, with a big untold story far from being told! And now we also have to place a WANTED tag asking for the tape version of Castle Dance with its loading screen, as .tap file. Gaia guess what, I have a request looking for YAPE 1.1.9: we need a DIGIMUZ card emulation
Hope to see all this and more very soon, thanks once again BKP!

back in the day, we didnt have much hardware and software for c16/+4. here in holland. most of the users were complaining about that and that was it! it is great to see that other guys just start to find everything out themselfs!
i didnt have the knowledge and maybe more important the patience!
but what i see what you guys achieved with allmost nothing. i take my head off for you!! thanks!!
it is great to see all the new-found-old-stuf!! i wonder what else will come up in the future!
as we can see the c16 and plus4 are not dead..

To update YAPE, Gaia needs to know the specifications of this extension (and I'm curious, too). Where is the AY/YM clocked from, what is the clock frequency? What addresses are assigned to the expansion and how do you access registers through them? What does that EPROM looking component do there?
By the way, I think the relevant hardware subsection should be renamed from SID Cards to Audio Extensions or something like that.

@Csabo, "So Metallic/FMJ is Tomasz Kiełbiowski?" - YES
@Luca, "so, its name is officially DIGIMUZ " - YES, AY extension for C+4 is a DIGIMUZ
@gerliczer, "Where is the AY/YM clocked from, what is the clock frequency? What addresses are assigned to the expansion and how do you access registers through them? What does that EPROM looking component do there?"
I have a schematic of this extension (I just need to redraw it cleanly). It has its own timing.
Addresses used in DIGIMUZ:
$ FD23- register number
$ FD22 - write to the register
$ FD21 - reading from the register
A very detailed description of all registers can be found in the datasheet AY-3-8910 (pdf).
You do not need eprom to handle the sound, but the constructor included additional commands extending the basic for AY support and a convenient turbo for datasette. Sometimes this eprom bothered me so I added an on/off switch. I never used the basic ones, the turbo was very useful

Hi BKP, awesome stuff, glad you could recover them. You said that the AY card had its own clocking but I need to know what the exact clock rate was... otherwise I'd assume that it was some multiple of the clock rate of the machine.

The FMJ Inc. spotted into the Castle Dance code returns in Mini Baza Danych and Cross Scroll Demo too, so have to argue about a *real* Plus/4 operating group, with BKP, Radosław Walewski and Tomasz Kiełbiowski, Full Metal Jacket Inc. (FMJ). Am I right? Can I ask for more juicy infos, which could expand into talking about the Polish Plus/4 scene in general?

@Gaia, I measured the clock frequency in my extension - 1.749MHz. The clock is made on NOT gates and it drifts slightly downwards with time. I think you can take a value of 1.75MHz
@Luca, I sent you information about FMJ on priv I would like to add that we lived in a tiny place where it was far away everywhere to get some materials (memory maps, programs, etc.) or go to a computer party and show off what we created. We acted practically only for ourselves, until after 30 years, finally some of what we created saw the light of day

The name "Full Metal Jacked" was invented and founded by Tomasz Kiełbiowski. Although it had a C64, we often collaborated, exchanging algorithms and technical solutions. We even ported the Genesis V2.8 assembler from C + 4 to C64 before it got TurboAssembler
Group members:
Tomasz Kiełbiowski "Metallic" - coder / graphic designer
Radosław Walewski "COMRAD" - coder
Sylwester Kuna "BKP" - coder / graphic designer / music composer
There is no official start and end date for the group's activities ... just 90s

Do you know that we don't have the V2.8 of Genesis Assembler V2.6? Were you in contact with other Polish users, e.g. exchanging software via snailmail? Can't wait to see all the other demos, and put my hand on the potential dozens of commercial games'cracks which should jump out from the hat of your tapes :)
Edit: Metalic or Metallic, like in Castle Dance? Comrad or COMRAD all caps?

@Luca, "Do you know that we don't have the V2.8 of Genesis Assembler V2.6?" - I noticed
@Luca, "Were you in contact with other Polish users, e.g. exchanging software via snailmail?" - Unfortunately, no contacts. I saw only a few times with TZ (constructor DIGIMUZ). It probably had the largest database of programs in Poland at C+4/16/116.
@Luca, "Edit: Metalic or Metallic, like in Castle Dance? Comrad or COMRAD all caps?" - Metallic, COMRAD
@Gaia, I did a little more research on the network and there was a 1.79MHz generator on the ZX Spectrum AY schematics - apparently it complies with the specification. There is nothing to worry about, since it works at 1.75MHz, it means that it has a high tolerance for deviations

There is also the option that CASTLE DANCE actually got corrupted during a hack by a friend. This version has been on my disk for a long time and on the emulator I couldn't check if everything was ok. I made a .TAP version from my original cassete which should be 100% correct. I'm sending it to @Luca.
Meanwhile, check if DEMO 2 or DEMO 3 plays correctly. It is also under DIGIMUZ. Regards

Thanks, DEMO2 and 3 actually do sound a lot better (I'd say almost right ). I'll try to post something during the day. Looking at my code I am not so sure what the expected behaviour is for the AY if the tone frequency is set to zero. Some eumlators reset the oscillators, some say it's the same as a freq of 1, the docs are completely silent about it...

@Gaia,
"http://gaia.atilia.eu/download/xscrolldemo.avi" - WOW!!! Sounds exactly like I made it
"Rgarding the TAP (thanks!), alas, it appears to exhibit the same sound artifacts as the PRG version." -
- Amazing ... I don't know how AY emulation works, but maybe something with the order of register completion is wrong, or with reading the memory above some value (I suggest you check it). I don't remember writing player anymore, but I didn't use any complicated techniques there. Most of my players had a common base which I developed with new functions.

@Gaia: Regarding TP register value 0 the manual really not says anything explicitly. However, there is this sentence: "Note also that due to the design technique used in the Tone Period count-down, the lowest period value is 000000000001 (divide by 1) and the highest period value is 111111111111 (divide by 4,095)." That may suggest writing 0 to TP should result in a different value. I read somewhere that 0=1. On the other hand, reading a random discussion of seemingly AY emulation developers of hackers yields another strange nugget of information. One person stated that the phases of tone generators are only after reset in a determined state, later they are driven in all directions by the periods, but writing 0 and the desired period back-to-back to TP register causes the channel phase to reset.

BKP thank you! I renamed the previous one as Castle Dance (no intro) and uploaded this most complete one. I took the liberty to cut off the last byte, saving it from $0800 to $77FF included only, cutting off the useless $7800.
BKP I saw into your releases several concepts from a mature 8bit scene which weren't common heritage in the early 90ies, like extending the background colors on the border (Castle Dance's titlescreen), or using a shadowmask with little softsprites to fade in 4 points the scrollings (Cross Scroll Demo). Does this experience come to you from other scenes, like C64 or the most spreaded in Poland Atari 8bit?

And one more demo (it was the first one) .TAP version only.
I have been sitting for a long time and analyzing jumps and the hell I can't find the starting address ... in my own program: D I'm out of practice. If someone wants to play in the search for the starting address and do .PRG try it. Theoretically, it should start at $ 52dd - it doesn't.
http://hostuje.net/file.php?id=1ae6ab8935f65258f5d8b1bcb666dc8f
@Luca, I watched some of the effects in other productions (e.g. additional screen lines), and then analyzed and developed them in my own way. The CrossScroll effect was simple and spontaneous - I have been dealing with electronics for a long time and logical operations are no stranger to me, I used it in the program :) I also did software sprites somewhere, but I can't find them.

@BKP: thanks for the feedback and the kind words! I noticed in Castle Dance you are writing registers 0-13 in a loop at once, while in Cross Scroll Demo there appears to be a different approach. One awkward thing is that in Castle Dance values (> $0F) are written into the coarse (high) frequency register which are higher order than the actally usable range.
@gerliczer: thanks for looking this up for me. Ironically, the TED has something similar where the lowest tone is actually $3FF as the oscillator counter's increment happens before the compare. I am not saying this is the case here as more sources suggest indeed that value 0 is in fact 1 but no word about 1 being 2 for example

@BKP: cool! You probably know that but lower ROM's are relatively easy to dump? Anyway, I suspect that the reason why these pieces of music are so out of tune currently in YAPE is that in some tunes it appears that some kind of lookup table is used (residing on the zeropage...!?). Without the ROM at this moment it seems to me that simply nonsense data is written to the frequency registers.

@Luca, please don't officially release this ROM yet.
Gentlemen, all of you here, I would like to say that I am very happy that I have met such people of brilliant programmers and computer enthusiasts that have almost gone into oblivion. This is a long story and you keep it going. Great respect and obeisances for the work you put into running this portal. By chance, I got to know @Carrion, who started this topic, and after 30 years I got a wider audience for my programs: D
Just thank you for what you do
PS. Sorry for my english but i use google translator
PS2. I will ask by the way :) I have three of my compositions in the Voicetracker standard (C64 computer) in the D64 file. Would anyone like to port this to C + 4 SID? Make such a small demo :)

@BKP: thanks a lot for this and your kind words. You see it is not every day that we stumble upon such treasures so obviously we are very enthusiastic! I have tested the ROM and it works great. Is there any documentation on its functions? One peculiarity is that at least in YAPE, the ROM fails to finish the initialization in case you have a 1541 drive attached. Once you remove the 1541, it loads fine.
As I suspected, some of your tunes in Demo1 and Castle Dance appear to use some kind of lookup table for the notes from the DIGIMUZ EPROM, hence it is out of tune if you run them without it. The 'cracked' version of Castle Dance does not work with the EPROM (it jumps to $0408 which is empty) so I guess there was no way to test it properly because few people had the actual extension (it would have crashed with the EPROM attached or would have been out of tune or no sound at all without the EPROM attached).
The original TAP and the 'clean' crack PRG versions you provided above, however, worked flawlessly so I managed to make a video. Here it is with my clumsy gameplay

I made a beta build available for you to see for yourself here:

WOW! WOW! WOW! I am impressed with the perfect AY emulation Congratulations on a great job!
Unfortunately, Yape does not work for me, because I have a 32bit system

@Gaia, I checked my daughter's computer. It took a while before I found the option to turn on AY, but it worked It works ok. I noticed a curiosity - when I do not mount the DIGIMUZ ROM, the sounds are played randomly, but when I press RESET (F11) in DEMO 2, the music plays correctly
(DEMO2 - has a RESET lock)
Unfortunately, I don't have a description for the DIGIMUZ ROM. I do not have a description of the basic extension written inside either.

@Gaia, you have a case of beer with me Thanks a lot!
How did I create these programs, that some melodies play in the emulator even without the DIGIMUZ ROM attached, while others require it? Even more strange is the situation with DEMO2. There, regardless of whether the ROM is present or not, the music is properly played only after a reset (F11). It must have to do with the interrupt vectors I think and memory management. I have too little knowledge to grasp it ... Anyway, it's great that I managed to emulate AY in YAPE. I am extremely pleased with that.

Hello, it's me - Mettalic. My friend - BKP - told me about this thread on the plus4word forum. Glad to see "Castle Dance" after thirty years. In fact, I forgot about her already. Now I will probably get the old C16 out of the basement and try to play. But ... I don't have DIGIMUZ and C16 doesn't work. I have a schematic. (Thanks to BKP) Time to repair the machine and make a sample copy.
Hey @Gaia. I have a small request. Can you add another AY-3-8910 to the YAPE emulator at the address $ xx40- $ xx5f? For the next 3 channels? I have an idea and such an emulation would help me.
Greetings gentlemen.
Tomasz K - Metallic.

Hey, glad to see you here Metallic (is it definitely "Metallic" and not Mettalic?), congrats for the surprising products you've contributed to in the 90ies, we appreciate'em a lot!
Usually, YAPE should emulate real hardware that actually existed, maybe are you asking for a special version? Anyway, Gaia will come and answer the right way, I'm just blabbling around

Hi Metallic/Mettalic,
If I were you, I'd reuse the same register window ($FD21..$FD23) as the single AY DIGIMUZ card. I'd use the unused upper bits of the address register ($FD23) to select the second sound generator. Or up to the eighth if you will. The I/O area is quite tightly packed already. It would be unwise further "littering" it if you ask me.

gerliczer has a valid point. $fd40-$fd5f is already in use by SIDCard (yes, probably you can't plug in a SIDCard and a DIGIMUZ together but existing software writing SIDCard registers can cause trouble.

Hello again,
Plague (who knows Witcher?), My mistake, of course, Metallic (some say it's from Metallica, but my version is from steel).
Of course. Maybe I'm asking too much, but maybe we can make YAPE an unpublished version of Γ (gamma).
@gerliczer Digimuz equipment allows you to connect additional devices in the address space:
$ xx40- $ 5f (extra AY-3?)
$ xx60- $ 7f
$ xx80- $ 9f
$ xxa0- $ bf
Regards, Tomasz K.
PS. You guess what I'm going to do? AY-3-8910 are terribly cheap.
PS.2 "This user name (Metallic) is already taken by Tomasz Kxxx" - How can I log in?

Metallic ah those addreses were specific of the DIGIMUZ hardware, just like SIDcard uses $FD40 and $FE80 as additional mirror memory location. Very good, if that's a real feature, Gaia will do it for sure, aiming to the most reliable emulation possible
Metallic isn't another user, he's *you* actually As you can see, no registration is needed to write here, but if you request for a registration, you'll become...Metallic, both as database entry and user If you wanna register here, click the word "registration" in the welcome message for the forum.

I continue to rummage in old cassettes for programs and finally found ... A demo version of the easy music composition program, which I started to create due to the lack of a good alternative - Music Tracker BKP. Unfortunately, I only did a synchronization of the player with the screen. There was not enough time to edit the music and the Amiga appeared, which made me dizzy and stunned with great sound For Amiga (and later PC) I composed a total of about 150 modules. And now I'm back to C + 4 from AY again
@Luca, the file is at the link below. I don't know how to add to my program list myself.

BKP, from the homepage, click [ Edit Page ], click Programs, click New. Or - my preferred method - search for the program you're about to add, if not found, you'll see the [ Add New Program ] link below the results.
