Kappamalone / recompiler_boy

A project to research dynamic recompilation techniques for the gameboy

Recompiler_Boy!

A Gameboy emulator written in C++ to explore dynamic recompilation techniques. Features an accurate interpreter, a WIP cached interpreter that translates the Gameboy's Sharp LR35902 ISA to x64, and (fairly) accurate PPU emulation. Most games that have their MBC implemented are fully playable (see below).

Features

• WIP Cached interpreter
• Passable emulation of most titles
• Some debug output and logging capabilities are available
