Ported this over the weekend, I think it's in a state now where some people will be able to use it. Initial reports are that it has issues running on CF-based carts, I only have a SuperCard SD to test with so I haven't been able to debug it on CF to see what's going on.
Copy it to your media, then copy over the Genesis ROMs you want to play (it should be able to play ROMs with .BIN, .GEN, and .SMD extensions). There's no sound, but since it uses the Cyclone 68k core which is optimized for ARM it runs well for the most part. Scaling is done in-software right now so the downscale isn't as fast or good as it could be. There's no double buffering yet so you might see tearing on some games. Y/B/A are A/B/C.
Compatibility is good for the most part, with some games it's hard to tell due to copy protection code. Pirates! Gold for example, has the same issue under my emulator and a few others I've tried where it just reboots every time you press a button, and I'm thinking it's due to copy protection stuff.
The emulator I'm porting has some YM2612/sound emulation code but I'm not sure how well it works (if at all), because it's not enabled in the original version either.
0.1.1版出了,貌似没什么变化
===================================
Okay, 0.1.1 is up now. Not any major changes, but hopefully a few fixes. The frameskip code was completely rewritten, and may be a little better now. Most importantly, the IRQ/VBlank code was redone and might fix the issues some users have been seeing where they just get a black screen after loading a ROM. A special thanks goes out to LiraNuna for helping me with these fixes and putting up with my stupid questions.
