C1/DTV PAL compatibility
Here's a little something for all you people who are curious about C1 and DTV C64 compatibility:
http://www.ling.gu.se/~pelle/deusex-palbeta-xvid.zip
It's actually running on the DTV development board, but the same core will be compiled for the C1 when it's done. As it's still in beta, a few things aren't working right:
* PAL phase alternation isn't working, so the colours are all wrong.
* Video output is "dirty" causing moving/flickering bands.
* 2-pixel $D016 delay is causing vertical bars to the left and right of the screen.
* An init bug makes the top left sprite black when the basic screen is moved out to the sides. It works if you power cycle before running, so it could be a bug in the demo and not the core.
* My video capture card has issues with $D016 interlace - this is not the core's fault :)
* $3fff should be covering the interference pattern, but doesn't.
* A few minor timing issues still remain, causing flicker in certain
I think you'll agree that C64 compatibility is decent though :)
PS: I didn't have a suitable cable, so I'm afraid there's no sound. I'll try to record some music later. |

Jeri fixed the PAL colour generation and the 2-pixel shift bug an hour ago, and $3fff is in the pipeline. The future is looking bright :)

The future does indeed look bright.
I hope you're keeping the nice soldering points on the board?
Shouldnt you be able to get your hands on just the boards cheap, and put them in a custom-made box with ports already there, and charge extra for those? I'd buy several :)
