The author of A/NES CGFX has decided to cease further development and is realising a final version today.
A/NES CGFX is a NES-emulator for 680x0 based Amiga-systems. It emulates the basics of a Nintendo Entertainment System (8-bit), and does it pretty well. Full speed emulation is not unusual even on slower Amigas. Except AmigaOS, it requires a 68020 processor or better, some Fast-mem and CyberGraphX v3+ (And yes, it even runs on P96).
