Resident PSP homebrew coder (and emulator guru) Zx-81 dropped by the QJ.Net Forums earlier to announce the release of PSPXTI: A TI-92 Calculator emulator v1.1.0.

As its name implies, this homebrew application is a PSP port of the Unix-based XTiger emulator (Unix version 0,8), based on Tiger Instrument's TI-92 calculator. The original Xtiger app was written by Jonas Minnberg, but was eventually passed on to Misha Nasledov under a General Public License (GPL). As for the latest changes in version 1.1.0:

* New user interface
* Use Virtual keyboard
* Use SDL library
* Render mode max (fullscreen)
* Add keyboard mapping menu
* New help window
* New background image
* Multiple keyboard mappings feature :
* You can now toggle between 3 different keyboard mapping using
* LTrigger and RTrigger keys
* Delete files option
* Bug fix in the file requester
* Compatible with firmwares 2.x, 1.5, and custom fw 3.X-OE.

Zx-81 further notes that you will need a ROM of TI-92 or TI-92 plus to get this app working. That's the skinny on PSPXTI's details - extra information can be found in the file README, Zx-81's site, and at the app's release thread at the QJ.Net Forums. With that said, enjoy the download!
