Meteors game now available as ROM

Tue Aug 7, 2018 12:33 PM

Hi all!

My Meteors game published by Intellivision Revolution sold out very fast in physical format, and even though Rev intends to manufacture more copies (send him PM if you want to reserve some) now I've made available the game in ROM format from my digital store. :)

Cannonball game ported

Sun Jul 8, 2018 6:46 PM


Yesterday I saw the Retrobattlestations challenge to show your machine running a BASIC program provided by @fozztexx.

The TI-99/4A wasn't in the ports, so I had to port it from PET BASIC, had a difficult time because BX% and BX were different names of variables and the % ones were integers, also because it was my first time using CALL functions.

But finally today I got the game working.

Hi everyone.


I've been working in this game ;) but not for cartridge form.


I'll reveal the mystery over the next few weeks ;)

Where to get TMS9918 chips?

Mon May 14, 2018 10:08 AM



After some testing I think the TMS9918 chip in my first TI-99/4A is fried.


I would like to replace it, but I see that eBay only has Chinese suppliers for the VDP chip.


Experiences? Someone has eBay vendor suggestions?

Pretty printer for TMS9900 assembler source code

Wed Apr 18, 2018 11:41 AM

Hi everyone.

I've enhanced my pretty6502 formatter to allow for TMS9900 assembler source code plus xas99 directives/syntax.

It works very well with my games Astro Cube and Borzork.

Of course it could need more testing ;)

Enjoy it!
