We all know that PSP users who haven't upgraded their firmware beyond 1.50 are able to run third party hobby applications as opposed to just commercial ones. This community has ported a large number of emulators to the PSP able to run almost every console game ever released. Apparently, someone also
ported the Basilisk-II 68k emulator which allows users to run a full copy of Mac OS 8.1 on it. Video
here (since that video was made a new version of the port allows for a much faster runtime).
