Last Updated2015/06/16

Portable homebrew-emulator for Pokémon-Mini on the NDS.


  • Windows (Development, Native and SDL), Linux (Development and SDL), Nintendo DS, PlayStation Portable and Dreamcast.
  • Debugger that allow to diagnose hardware internals or modify them (Development package only).
  • Development tools for programming your own homebrew to the Pokémon-Mini.
  • Sync Cycles option which allow improving performance at cost of accuracy.
  • Unofficial colors support and enhancements.


To include real BIOS, place bios.min on the emulator's directory. When no bios.min is present, emulator will use Pokémon-Mini FreeBIOS.
