Haxe NES Emulator
This emulator cannot run any game currently
Currently mostly an complete 6502 CPU VM, with unofficial NES instruction added
PPU is currently absolutly not supported. It will be handled in a future version.
To compile Hemu, you'll need the lastest 3.0 Haxe version and the 2.0.0 Neko version.
Create the folder bin with mkdir bin
Then, just run haxe make.hxml will produce the out.n file in the bin/ folder.
You can run test with nes_test_diff.sh, or run a random rom with neko out.n random.rom
