DSx86 v0.05 Alpha is released. 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.

DSx86 v0.05 Alpha Changelog:
- CGA mode now supports both DIRECT and BLITTED screen update modes.Direct mode is faster, but not all opcodes are supported, so if you get unsupported opcode problems when using DIRECT mode, switch to for example 30FPS mode and the game should run.
- EGA mode improved, now runs Commander Keen 4. Still a lot of EGA features remain unsupported, so this still needs quite a bit of work.
