Gearboy v3.8.0 has been launched. Gearboy serves as a Nintendo Game Boy emulator developed in C++. This emulator prioritizes source code readability while still ensuring solid compatibility. Considerable effort has been dedicated to implementing OOP principles and simplifying the design.
Gearboy Features:
– Highly precise CPU emulation, successfully passing cpu_instrs.gb from blargg’s testing.
– Accurate instruction and memory timing, passing instr_timing.gb and mem_timing.gb from blargg’s tests.
– Memory Bank Controllers (MBC1, MBC2, MBC3 with RTC, MBC5), ROM + RAM, and multicart support.
– Exact LCD controller emulation for backgrounds, windows, and sprites, with correct timing and prioritization including mid-scanline timing.
– Frame mixing: Simulates the original Game Boy’s LCD ghosting effect.
– Sound emulation utilizes SDL Audio and the Gb_Snd_Emu library.
– Game Boy Color compatibility.
– Built-in disassembler can dump complete disassembled memory to a text file or allow real-time access.
– Saves for battery-powered RAM cartridges can be stored to a file.
– Save states functionality.
– Support for compressed ROM files (ZIP deflate).
– Game Genie and GameShark cheat functionality.
– Cross-platform support: Runs on Windows, Linux, Mac OS X, Raspberry Pi, iOS, and as a libretro core (RetroArch).
