there are psx emulators for the xbox, never tested them..
sometimes the emulators do not work on the xbox also..
like daphne, i was wondering why this emulator was giving errors on dxbx.
and what is the case ??? the real xbox was giving the same errors when running daphne emulator.
So multi emulator no... but there are realy alot of emulators availible for xbox, so if the xbox emulator dxbx or cxbx is good working you can run emulators in your emulator
The most powerfull thing to know.. if emulators are working good in the emulator... so running for example working psx emulator in dxbx or cxbx.. and that is working correct and at a good speed.. then you know your routines have a good performance.
