Yeah, emulators aren't designed to handle this... neither Gens/GS nor Fusion handle it correctly. It works great on my CDX - very stable. Any source on this? I'd like to do some experimenting with it.

as soon as I can be bothered to boot up my old barebone again

(I wrote the code on a tiny athlon XP box :X)

Cool - thanks! No rush... I got PLENTY of other things to keep me busy.

Thanks! Hmm - I'll have to dig into the VDP commands. Definitely an interesting program to study.

Darn, I can't get Oerg866's FantomBitmap to run on my Model 1 Genesis with the Mega Everdrive . Is there something I can do to remedy this problem?

Just check the 960 colors demo on this page :

This also seems to not work well for me . The palette is unstable, it rapidly scrolls vertically on the screen.

Sounds like it might be PAL and you're on NTSC. While you can set the extended height mode (240 lines instead of 224) on an NTSC console, it causes the display to spaz out because NTSC only allows for 239 active lines, so the extra line interferes with the vertical blank signal.

Does anyone still have this BITMAP.zip file with source code by Oerg866 ?
