XTiger is an unix emulator (under X Window) of a TI-92 calculator (Texas instruments).
It was originally written by Jonas Minnberg and was closed source.
Jonas Minnberg has not worked on XTiger for quite a while and he gave Misha Nasledov the code and permission to GPL it.
I've sucessfully modified and port the source code of the 0.8 version using PSPSDK environment.
It's now working fine on PSP !
The package is under GPL Copyright and sources are included.
I've tested it only on PSP with FW 2.5 using Fanjita GTA loader, but it seems to work also on 2.x, and a 1.5 FW version is also include (generated using upspear 0.1).
Many TI92 stuff can be found on the following urls :
