Today Evilo has announced Wonder-Station, a wonderswan color emulator for the ps2. The emulator has only been in development for a very short period of time and has reach amazing level of compatability. There is also full cdrom, mc and hdd(experimental) support in this version so no n00bs can cry about hdd support. If all goes well there will be only one updated version when the source is released( so it can compile correctly with the latest ps2sdk).
