Zx-81 has ported over BeebEM an emulator of the BCC microcomputer series to the PSP. BeebEm is a famous emulator of the BCC Micro computer series running on both Windows and Unix.
Originally developed for UNIX systems in 1994 by David Alan Gilbert, it was then ported to windows by Richard Gellman and Mike Wyatt in 1997. At the start of October 2005, David Eggleston started porting the current Windows version of BeebEm (version 2.3) to FreeBSD. I've sucessfully modified, and port the source code of the 0.0.4 version from Dave Eggleston using PSP SDK environment. It's now working fine on PSP!
It has been developed on linux for Firmware 2.5 using the GTA Loader (0.97), but it should work properly on other Firmware. I've integrated a 1.5 FW binary version (KXPloit). It's a first beta release and work still remain... Sources are included, and this package is under "Beebem" licence, read copying.txt file for more information about it.
