ZoomBlox is a game for the Texas Instruments Ti99/4A home computer, placed 2nd at Evoke 2025 interactive competition!

Your objective is to clear as many blocks as possible before the screen moves down and crushes you. Several game modes are available for a different challenge every time!

The game image can be played on an emulator (like the online Js99er or Classic99 for Windows), or on real hardware through a cartridge emulator like FinalGrom and a 32K RAM expansion. You will soon be able to also purchase a physical copy in cartridge format along with the 32K RAM expansion!

You can download the full game here. You can also check out a video of the gameplay here.

What started as a proof of concept for a development toolchain on the Ti99/4A eventually became a full and enhanced port of my Atari 2600 game Space Treat.

The game has been released at the Evoke 2022 demoparty to warm reception and a mention in the "best newcomers" category.

The ROM file can be played on an emulator (like the online Js99er or Classic99 for Windows), or on real hardware through a cartridge emulator like FinalGrom and a 32K RAM expansion. You will soon be able to also purchase a physical copy in cartridge format along with the 32K RAM expansion!

Thanks so much to Mat64 for the amazing work on the aural department!

VGM2XB can convert VGM songs/modules to a friendly and very compact Ti99 Basic and Extended Basic (XB) format.

The VGM format is a very popular and widely adopted song/module standard across many platforms of 8-bit computers and consoles.

It can be generated using tools like, but not limited to, "Mod2PSG2": https://www.smspower.org/Music/Mod2PSG2
