Friday, March 31. 2006PSPXTI: A TI-92 Calculator emulator v1.0.5 (bug fix)![]() ![]() Hi All, 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 all presents in the original source code of Xtiger. Those bugs are fixed now. This version works with 2.xFW. and 1.5FW. pspxti-v1.0.5.zip It's distributed under GNU licence and sources are included. Enjoy, Zx. Trackbacks

i have display problems, using a 1.5 psp, and the rom included in the zip, and i tried others rom files, but the same, the display of te calculator show without problemas, but cannot see the "buttons" just a black image....
Ah... I messed it up. Where do I get the .rom file? because, I wanted to update the ticalc, but then when I updated it, nothing worked in the calculator except only the analog stick. Then I tried to reinstall it and it doesnt work anymore. I'm using 2.6FW. The only thing i have in my pspxti directory is:
eboot aqua classic ti92.rom and I got the ti92.rom from the link you gave us on the first version on yoru page... What it does now is I go to the Eloader, select PSPXTI, and it goes to a black screen and goes back to the eLoader. I hope you can help. I don't understand, it should work properly on 2.6. Remove the directory and put all files from fw2.0 directory to your memory stick. in directory PSP/GAME/PSPXTI
The rom i use is the same version as this one : http://icln.sfcc.edu/mugs/Atec%20Workshops/Math%20Resources/TICalc/ROMs/Ti92+.rom If the screen is black, it means that the emulator was not able to load xti-aqua.bmp or xti-classic.bmp image. Zx. why is it when i do sqrt(55) it give me an answer of sqrt(55)? Instead of 7.41xxxxxxx. ? Also, when I do a simple sqrt(9) it gives me 3. lol.. I'm scared to use this calc now.
If you want a numerical value (approx) you have to use the diamond key and then ENTER.
This calculator is very complex to use, and you have to read the manual to be able to use it. A link to a PDF version of the TI-92+ manual is given on this blog. And about the bug, all software have bugs, i've fixed 12 errors on the instruction set of the 68k processor, and i think there is no left in this part of the emulator. is this calc. reliable to use? i mean to use it for real...
thx for the app, one of the most useful ive seen :b hi,
i am trying to install ti92+ to my psp. i am using 2.6v. i copied the files to my memory stick including .rom file. but in my psp when i go to games and open pspxti it gives me a error saying "this game cannot be started. the data is corrupted" plz help sorry i didn't know u have to use eloader to run this program. but i still have problem running this program. when i run pspxti from eloader i get a black screen and then the psp get turned off. please help. thank u
This is an amazing program,(actually i think its the most useful program to develop in the homebrew scene) however most college students use the ti-89 titanium, is is possible for you to write an emulator for this calculator as well?
