In case you don't visit the XBOX (original xbox, not X360) news sites, I'd like to announce
the release of my Capcom System 3 (CPS3) emulator for XBOX.
It's a port of CPS3 Emulator to XBOX with a nice fullscreen GUI that is able to run
most of the CPS3 games at full framerate.
The XBOX system CPU is just barely enough to run the CPS3 emulation, so some
optimizations have been included, and the shadow emulation is not accurate, because
the correct emulation doesn't work at full speed in the XBOX CPU.
Also in order to make the games fit in the small XBOX RAM (64MB) , the emu makes use of
virtual memory, using a swap file in the hard disk, so it can show some hiccups when a lot
of data has to be moved from hard disk to memory (stage changes, flashing images,...)
Since the emulator is built with the XDK, I can't provide a direct link for it, but you can find
it at the usual XBOX Binaries sites.
