With MESS being MAME's sister, does it get the same attention with hard-to-dump or hard-to-get ROMs like MAME? Take for instance the Microvision ( http://en.wikipedia.org/wiki/Microvision ), 2KB ROMs are located inside a TMS1100 MCU.

Certainly if someone could round up the carts we could see what could be done with them.

The CPUs are also on the cartridges, afaik these things are pretty hard to dump...

Most likely. Games are up for grabs though, if you happen to be a US citizen with an eBay account.

The hardest dumps to find will be from the Taiwanese Super A'can, it looks like a pirate snes clone but is infact completely original and very obscure.



Screenshots and cart photos

I'm a console collector from the UK and these things are rarer than hens teeth, although I would like to see the Apple's failed console effort emulated before this, its a shame the Pippin is 500 a pop, heh.

On a side note, I have a spare PsOne (SCPH-102) that i am willing to give somebody for dumping. I read how the other PsOne was dumped and it requires a memory card reader which i dont have. You can keep it once its dumped too but it has no cables.

(sorry for hijacking your thread)

I can't imagine a late 70s MCU can put up much of a fight against Guru's array of programmer/readers, but stranger things have happened :-)

Re: the Pippen, that'd be fun to have emulated, but isn't it pretty much just a first-generation PowerMac with a custom BIOS? I'd like to see more Macs going in MESS in general, mind you, but it seems like trying to specifically emulate it before we get to the PowerMacs it's based on would be silly.

gamate dumps are also not that easy to find.

Hmm, I always thought the Gamate was just a standard lcd block game, I never knew it had removable cards.



Those cards look an awful lot like the SMS cards, I only have 1 (there are only 6 different games on these cards) and im not sure if they are dumped.

I've got a complete collection of Microvision games--definitely an historically interesting system. From what I've read the MCU has a test mode that could be used to read out the ROM contents, but it's likely someone would have to build an adapter and figure out what commands to send.

I just mailed a big box of games and systems to Guru a couple of weeks ago, but once those are taken care of I'll have to ask about the Microvision. Of course if anyone else is interested, let me know.

I've heard mixed things on the dumpability of TMS1100, some sources say it does have a test mode that allows it to be dumped, some say it doesn't. If it does, it's not a documented feature.

Supposidly the earlier cartidges used an Intel 8021 which is a variation of the 8048. Since the 8048 it dumpable, it's possible that the 8021 is also.
