From a hardware standpoint, it is entirely possible to dump the ROM from the original cart, rip the code from the Teensy, and make repros. I know this because one person (Matt Payne?) Made a Nomad-friendly controller dongle himself.

Sorry, what I said was in reference to the eBay GenMDM's. I strongly suspect they are clones.

Hmmm very interesting. I again want to ask DSC to chime in with his side of the story.

Well, the reason I say this is the controller port has its own unique non-littlescale PSB with MIDI port installed... Would love to know where it came from considering littlescale never made such a thing (I believe)...

He did post instructions on how to hack in a midi port, and the second revision was going to include one (I think).

In other news. Who is mmmprpl on ebay? is this you DSC? and could this be kindly explained to how you/they have such a large supply of them?
It's looking an awful lot like what wayfar(sykdeity) is doing.
I don't want to jump to any conclusions but kind of scary.
Not to continue with a banned subject but Littlescales' design and source is part of his Thesis project and published at https://digital.library.adelaide.edu.au … 2440/70888
So perhaps someone has cloned it based on the published data?

Someone pointed me to this recently and seemed the best way to pass it along, I wouldn't suggest that anyone infringe on copyrights but how people use the information in their own home is not for me to decide...

Hmmm, another unit sold on ebay and as I expected another listing was immediately reinstated to take it's place.
I guess I'll just leave the following as my evidence for accusing DSC to be mmmprpl. I mean I'm aware he's the guy behind ninstrument.com, so burning some simple eproms and making a simple pcb for the midi port and teensy is well within his capabilities.
GenMDM threads linking to the mmmprpl ebay member:

Isn't GENMDM just MIDI -> commands via some serial protocol over a joystick port -> Register writes -> Sound output?
The source for SMSM is pretty bare bones, I'd imagine GENMDM is the same way.

Yes as I understand it. The Teensey does all the work. The Sega ROM just loads registers.
EDIT: after a basic read thru of the source code, the main loop of the GenMDM run on the 68000. There is a 'Z80 driver' loaded into the Z80 ram but the 68000 seems to do all the writes to the YM and PSG.

yea, Supply and Demand. Its like the cartage collector market, some of the prices paid for a rare title are obscene, to me. But the value of anything is what someone will pay for it.
