Home Page Forums MAME MAME Coleco Total Control 4

Hello, just wanted to say that I have a coleco total control 4 with all the game overlays. I plan on taking it apart and scanning the artwork, and will see about adding it to mess. I'll post more updates soon! I've also updated the page on the wiki to say that I have the system.

Interesting, but how will you add it to MESS? Did you dump any internal ROMs? What CPU does it use?

It uses a TMS 1400, I'll have to find out how to dump it, and if its already supported by MESS. I've only found tms5501, 9901, 9902, and 3556.

There are only two other ICs on the board ones an sn75492n (LED display driver), the other is under the LED display and is also probably a driver.

If I can't figure it out i'll send the system to someone who can. But it looks simple enough where it would be fun for me to get it added to mess myself, with maybe a little help.

According to this page, the TMS1400 is a microcontroller in the same family as the TMS1000 (used in the Speak & Spell) and the TMS1100 (used in the Microvision). Dumping these is not trivial, but Lord Nightmare was working on it last I heard. Judge was also working on a CPU core. If these work out, expanding to the TMS1400 might not be too difficult, depending on how different they are.

I wasn't familiar with the Total Control 4, but found its Handheld Museum page. It has cartridges, but they actually just physically control a switch on the system circuit board. So all that would need to be dumped is the TMS1400.

Personally, I would love to see dedicated handhelds like this emulated. There are lots of them out there, and they've pretty much been ignored so far.
