fTNES

Currently a 6502 microprocessor but working on PPU
to emulate Nintendo Entertainment System(NES), written in C
Likely will remain unfinished TBH

Features

• Full emulation of the legal CPU opcodes
• Emulation of primary system components I/O
• Support for NROM, non memory-mapped
• Rendering of OAM Sprites

Prerequisites

• A C 64-bit compiler (ex. GCC, Clang, MSVC)
• Simple DirectMedia Layer (SDL2)
• Basic make and lib linking knowledge

Building

mingw32-make make

Running

./main path_to_bin or 'mingw32-make run'

Roadmap

• Implement primary opcodes
• Timings and Interrupts
• Finish OAM and Nametables
• Cont. PPU Registers
• Streamline build
