ok, for those that surf similar sites to m this won't be news but...
'Richard Bannister has released Oswan, the very first Wonderswan emulator for the Macintosh. Oswan is Richard's first emulator to only run on OS X (10.1). It only took a day to port and whilst there is no sound compatibility is high.'
this is straight from mac emu.
i don't know why a wonderswan emulator is so interesting to me, perhaps 'cause you can't even buy an imported one in an australian shop.
anyway for those interested!
