This version of the classic Breakout game has the rare distinction of being programmed entirely in GPL, an intermediary language somewhere between Basic and assembly language unique to the TI 99/4A computer. Download Texas Instruments TI 99 4A Cartridges ROMs and Games for PC,iOS or Android Phone. For those interested in game programming on the TI in any language or skill level, or if you are just curious, the AtariAge TI 99/4A programming forum is the place to be and where most new games are being generated. Check it out!

This page is a slight dedication to the TI-99/4A Home Computer, my first computer. (The Tandy 1000 SX was my second computer.)

(Our) TI-99/4A History:

The Texas Instruments 'TI-99/4A Home Computer' was my first computer (and Jason's first computer, too).

It was on this computer that I learned how to program, optimize code, and how computer graphics worked. I designed and programmed lots of incomplete games on it as a child. I still remember when I figured out GCHAR meant 'get character', which meant I could read the screen, which meant I could (all-of-a-sudden) make game characters interact with objects and levels on the screen. At the time, it was a big deal. It was an unbelievable discovery. I think I was in grade 3 at the time, trying to learn TI-BASIC from a reference manual. Non-programmers may not understand, but the ability to make your game characters interact with your environment was an awesome concept to implement when you first realize how it is done. I fully completed my first game when I was in grade 4, called, 'Treasure Hunt'. It was a simple maze game. Some of the code still exists somewhere on a cassette tape.

Treasure Hunt, my first complete video game ever, on the TI-99/4A.
(I am not sure what 'Threaded Blanket' is.)

TI-99/4A Games:

A few of my favorite Cartridge games on the TI-99/4A were Parsec (especially with the speech synthesizer), TI Invaders, Munchman (not Munch-Man), and Car Wars. Here's a few we have articles on:

TI-99/4A Emulators:

Classic99 (previously known as Ami99) is the TI-99/4A emulator of choice. It includes system ROMs and cartridges under license from Texas Instruments. This is a big deal. Normally, emulators are only that, emulators, without cartridge/games ROMs and also without the system ROMs (the preset memory that comes inside the system itself.) Classic99 solves all of this. Just download it, and run it. Also, it is open source and 100% free. Simply amazing work.

Fan Mail

I love sharing the fan mail I receive. (I always ask before posting, so have no fear of contacting us, too!)

Hi Matthew & Jason,
I just wanted to say I enjoyed your facts about TI99A computer, this was also my first computer.
I worked at Texas Instruments in UK at the time & we were able to buy warranty returns and discounted products from the Staff Shop, so lucky me. I had Parsec, Alpiner, Hunt the Wumpus, Invaders, Munch Man, Tombstone city cartridges and learned TI Basic. I wrote a 3 wheel one armed bandit type game & spent hours with that 64KB ram.
Thanks for the Memories

Another one from Stan, links (other than his YouTube footage) added by us. I believe Stan to be the youngest TI-99/4A fan I have met so far:

Hello Matthew,
I came across your PARSEC page a few weeks ago after downloading the Classic99 emulator. Since then I've not been able to stop playing!
Thank you for the hint to hold both fire keys down, I wasn't able to ever get past level 3 in all my years of playing (our original TI99 system died when I was 12; I'm 38 now); but after discovering that little glitch, I was able to effectively beat the game!
After that I tried my hand at Car Wars. Had never gotten past level 4 in that game but now I have beaten it too. Here's a link to the youtube video of level 6 repeating:

Keep up the good work!!
