Zx81 has updated his PSPXTI to version 1.0.4. PSPXTI is a PSP port of XTiger emulator of TI-92 calculator, which originally runs under X windows in UNIX. This emulator works on 2.50 with the eLoader, and should be working fine under v1.50 PSP too. Here is the message from the author on this version:

Hi All,

I've just released the version 1.0.4 of the PSP TI-92 calculator.

We can now toggle between classical skin and aqua skin inside the emulator! Some minor bugs have been fixed in the keyboard handler, and it should be more stable now. This version works with 2.xFW. and 1.5FW.
