Emunes

NES emulator written in C using win32api. Information regarding the NES architecture is from the NESdev Wiki.

Features / limitations

• Only includes the legal instructions of the RP2A07 / RP2A03 cpu, which makes many roms not work
• Sound is not implemented
• Only Mapper0 is implemented, which limits the games which can be played (see here for a list of games)
• Only one controller on port 1

Instructions

• Compile the emulator with compile.bat (requires gcc)
• Start emunes.exe and click file > open to load your rom
• Controls using the arrow keys as D-Pad and A = X, B = Z, START = ENTER and SELECT = RSHIFT (These can be changed in controller.h)
• In the options you can toggle some debug info, this includes the current cycle and instruction
• The emulator logs to emunes.log, and the CURRENT_LOG_LEVEL can be set in logger.h (default is LL_INFO)
