PSPXTI: A TI-92 Calculator emulator v1.0.5

Always looking for a legitimate reason to whip your PSP out during class?  Well, the author of the TI-92 Calculator port (ZX-81) has just released an update.  So as most professors / teachers state that we need to get out and purchase a graphic calculator for trig or algebra, feel free to use your PSP instead. Here’s what ZX-81 had to say:


I’ve just released the version 1.0.5 of the PSP TI-92 calculator.

Computation errors have been found in previous versions of the emulator, and for example ln(x) function gave false results for x < 1.0.

After a long period of bug tracking, errors have been found in 12 instructions of the 68000 processor emulator.
Those bugs were present in the original source code of Xtiger and they are all fixed now.

This version works with 2.xFW. and 1.5FW.

It’s distributed under GNU licence and sources are included.
