DSx86 is a PC emulator for Nintendo DS. It’s purpose is to allow you to run old DOS games on your Nintendo DS game console.

Currently DSx86 emulates the following:

* 80186 processor (which is actually a 80286 processor without the protected mode stuff)
* MCGA graphics adapter (a stripped-down VGA with a maximum resolution of 320×200)
* SoundBlaster (including AdLib-compatible FM sounds) sound card
* 83-key US keyboard
