Software Development


  • devkitARM - C/C++ cross-compiler toolchain, which includes libgba, libtonc, maxmod, and various tools and example projects.
  • gba-toolchain - GNU Arm Embedded Toolchain based alternative to devkitARM.
  • gvasm - Stand-alone assembler and disassembler (WIP) designed specifically for GBA homebrew


  • rust-console - GBA programming in Rust, plus tutorial.
  • natu - GBA programming in Nim (provides wrapper around libtonc, maxmod and more).
  • gba-modern - Write GBA games using modern C++.
  • ZigGBA - WIP SDK for creating GBA games using Zig (Inspired by Tonc).
  • Butano - Modern C++ high level engine for the GBA.
  • BPCore Engine - Create GBA applications with the Lua programming language


  • agbabi - Drop-in application binary interface library (context switching, division, irq, memcpy, sine).
  • gba-plusplus - Modern C++ alternative to libgba and libtonc.
  • HeartLib - Comprehensive C library inspired by the classic HAMLib.
  • libseven - Lightweight, from-scratch replacement for libgba.
  • GBAdv - High level utilities on top of libgba.
  • Maxmod - Music and sound library (supports .mod, .xm, .s3m, .it)

  • Pimpmobile - Music library (supports .mod, .xm)
  • posprintf - An
    routine written in Thumb assembler.
  • GBFS - Practical filesystem


  • mGBA - Actively developed GBA emulator. Runs on a bunch of platforms. Text debugger through GDB stub.
  • No$gba - Venerable GBA emulator. Windows only, but runs well under Wine. Not very actively maintained but still gets updates now and then. Sports graphical debugger.
  • NanoBoyAdvance - GBA emulator with high accuracy, especially in timing and CPU emulation. Currently lacking a GUI or debugger.
  • MiSTer FPGA implementation - Needs MiSTer setup to run.
