DS2x86 by Patrick Aalto 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. DS2x86 is a port of DSx86 port using the SuperCard DSTwo’s MIPS processor, therefor it will just run with such a card.

Release notes:

This is mainly just a quick fix version, to fix some issues in the 0.20 version with a few more FPU opcodes implemented. The new FPU opcodes are fsincos, fptan, fprem, fyl2x, f2xm1 and fscale. The first three I have not tested properly yet, so those might have some bugs. The last three I have tested so they at least should work properly.

At least two new games seem to be runnable (or at least startable) in this version, Abuse and Comanche. Abuse needed just a few more FPU opcodes implemented to start running. Comanche however had some more problems.
