Me and a friend recently spent loads of time getting basilisk II to work properly on the PSP and we have. We have put together a freeware tool we found on the internet for editing DSK files, Also we have made a DSK file with a game of checkers on it and a game of chess also a JPEG viewer .... We have installed the mac os7 on a Virtual DSK Image ... Also included is a copy of mac.rom ... It is surprisingly Quick. Some window moving things cause it to hang such as scrolling the horizontal scrollbar. Shutdown causes it to hang so just use Home button to quit.
