XZ81 is an emulator of the Sinclair ZX81 computer running on Unix systems.
It has been written by Russell Marks in 1995.
See http://rus.members.beeb.net/ for further informations.
I've sucessfully modified, and port the source code of the version 2.1 of xz81
and it's now working fine on PSP !
How to use it ? Everything is in the README.txt file.
Sources are included, and this package is under the GNU public licence,
read COPYING.txt file for more information about it.
Special thanks to all PSPSDK developpers.
