Finalburn Alpha is an emulator for MC68000/Z80 based arcade games. It is the successor of FinalBurn that adds more features & compatibility like Neo Geo support to the original that has been discontinued.
Changes:
Cosmetic improvements, sound code improved (optimised and some parts rewritten), uses mmu hack, change of SDK (from Minimal 0.C to Minimal 0.B). The downside being that some games now run too fast! Some however (like 1941) still run like a complete dog. ROM loading still the same as per previous version.
