 Is it a cause to envy?

This is a link to Amstrad CPC 2016 game video
https://www.youtube.com/watch?v=HVv-oBN6AWA
It looks great, the same as at Amiga. This shows that 8-bit 6502 or z80 might match 16-bit CPU...
C64 Pinball is much worse. IMHO C+4 with 256 KB RAM may do graphics close to Amstrad's.

 Re: Is it a cause to envy?

That's mainly not a cause of cpu power. The plus/4 can easily handle a pinball games physics engine. The only real problem seems to be (again) the missing sprites. I think the graphics also would fit in memory. The c64 dudes did it also. Like the cpc coder wrote, a big problem are the jingles. He left around 16k just for the sound. It would be a tough task to fit this game into 64k, but if the c64 guys get it done, then it could be doable.. Ah wait, for the sprites you need a doublebuffer ..

Oh and perhaps the game should be checked on a real cpc, rhino the author wrote, that they are using interlace somewhere to get more colors.. but maybe that's wrong..

edit: it doesn't look like interlace at all.. here: https://www.youtube.com/watch?v=-tcsxUtMj5I

Amstrad CPC has no hardware sprites too. It can use slow pixel graphics only, no text modes.

 Re: Is it a cause to envy?

It was nothing about performance. On the plus/4 you can't have a colored sprite. It would be possible to draw perhaps a white ball (or perhaps two colored), though happy! Not sure about this, never wanted to code a game like this, perhaps it's possible even without a double buffer by triggering the paint and remove of the sprite on the right rasterlines. Thanx for the correction! :)

edit: perhaps it is even a bit more easy to code this on a plus/4 than on a c64 because of the hardwarebitmap scrolling. However, I would not try it!

the c64 version: https://www.youtube.com/watch?v=ls6pxVKttQ0

edit2: In the video for the c64 version is stated, that it never will get finished due to the low memory. So Litwr is most probably right about the memory issues.

The CPC has a 160 x 200, 16 color, 4 bit per pixel graphics mode.
No color clash or color attributes.

 Re: Is it a cause to envy?

I was very impressed by the Amiga ball in Rocket science. I was very surprised several days ago when I had discovered that the same effects were made in 1986 by 16 years boy for Amstrad CPC - it was shocking. https://www.youtube.com/watch?v=m9Go8cwSDzQ
This demo was made much faster in 2016 and packed in 12 lines of Basic code (it is at the comments by Zbyszek Rumiński)! IMHO it maybe done for C+4 too...
