As for Afterburner and Galaxy Force, I was wondering what happened to them as well. I'll look into the source some more and see if they are still supported. It would be strange for them to be gone, as it's how it started!
Thanks for the support. I also didnt realise hardware "fine scaling" was figured out on the GP2X. Is CPS2emu using fine or coarse scaling?
The hardware scaling gives the standard ugly "blocky scaling". There is a mode called *sw* scaling horiz only which is a SoftWare scaling mode that eliminates 1 column of pixels (every 6 I think) to get the image to fit. It then averages the pixels only in that column so that it looks smooth without blurring out the entire image. I think it uses a similar tecnique that Pico Drive does to scale horiz only but to compress rather than stretch. Notaz says that scaling and averaging one horizontal direction only is possible in software without killing the CPU time alot. The averaging routeen was in ASM. Look in the Picodrive thread. CPS1 and CPS2 games are very close to full screen vertically with tiny bar at the top/bottom. This mode leaves the image size alone vertically and only compresses horizontal. It looks alot better than trying to stretch vertical too making the image blocky only to gain 1 mm or two.
