TI99Sim is a very good emulator of Texas Instruments
TI99 home computer running on Windows and Unix.
The emulator faithfully imitates the TI99/4 model
PSPTI99 is a port on PSP of the version 0.1.0 of TI99Sim.
What's new then in this version ?
- Speed improvements
- Add vsync and autofire options
- Add several new hotkeys :
. settings such as fps, render mode, auto fire speed
can now be directly modified inside the emulator
(no need to enter in the settings menu)
. quick save / quick load current state
(no need to enter in the main menu)
- Default Hotkeys can now be set in the keyboard mapping menu
(useful to add hotkeys on existing/previous keyboard files)
- Bug fix in the low battery watchdog
How to use it ? Everything is in the README.txt file.
If you want to convert games etc ... have a look to Ti99/sim web site
for more informations (http://www.mrousseau.org/programs/ti99sim/).

thanks for this emulator! here is 1 question
all the games I have are the file extension .TICart , will this emulator eventually support this extension?
thanks in advance!
Take the rom pack above , or you need to convert them using tools part of the original Ti99Sim emulator (have a look on the author web site)
Is there a plan to convert this nice emulator also to Nintendo DS?
NDS is far a way slower than a PSP or a GP2X, so i guess i have to rewrite it all to make it works under DS at a descent speed ...
I do not plan to do it in a near future,
Thanks so much for releasing these older system emulators for the PSP. I grew up in the 80's and I remember all these systems (Atari 7800, TI, etc.) Do you also remember how much they were to buy back in the day? Growing up I thought when I'm an adult I'll have a room with every system in there. With the PSP I have them all in a small, portable device.
Even in the late 80's/early 90's I bought a TI-99/4A and a lot of the cartridges at local thrift stores. Nice to have, but it takes up a lot of desktop space.
So great to be able to put them all on one device and carry them around with me.
Hi Zx......Is there any way to use a disk file on this emu? I would LOVE to play Tunnels of Doom on my PSP! Tanx
Thanks for this port!
Nothing important, just a little remark: I played Popeye from the romset linked above. It is playable with the analog stick, but I'd rather use the digital pad. Unfortunately, it seems that I can't move diagonally when using the digital pad. Diagonals are essential to playing Popeye, however. If you consider releasing another update, perhaps you can have a look at that issue. But, as I said, nothing important. Thank you!
