I've compiled a very early version of a wonderswan emulator for dingux. It's based on Oswan port.
It has these known bugs:

• It doesn't have a rom selector, you must launch a rom with a script like: ./emulator rom-name.
• It doesn't have sound. This port is based on Seal library and I'm changing it to SDL_mixer.
• The game is not shown propperly on the screen, it just show one part of the game.
• No zip support for the moment.

Inside the zip file there is the dSwan executable, a homebrew game for the WS and an script to launch the emulator called dSwan.sh. You have to launch this sh. Press select button to exit.
