ok =) kevtris will help me out with the tntell pinout when I get stuck, there's no need for a detailed description for it then. Most of it is already documented here: http://www.burnkit2600.com/touch-and-tell/

Touch & Tell is added to MAME, it doesn't work like it's supposed to and Vocaid doesn't work at all. For now I assume the patent code has typos/bugs or is incompatible. The code in the T&T TMS1100 labelled CD8012 is completely different from the patent code. I'll double-check the bits some more then upload the dump.

Thanks! I'll doublecheck and add it.
Looks like the die was affected by king Midas's touch (but not tell) - badum tssh :|

 I cleaned the die in hot nitric acid a couple of times but the giant glob didn't come off. When I whinked the chip, enough came off to see the ROM array, but I guess it had protected the passivation layer enough so the metal didn't get dissolved. I'll whink it again when I'm doing other chips and make sure those bits are correct.

Confirmed, and one more fix, so:
raw file, offset $08, change $2E to $6E
and offset $698, change $22 to $23.
I don't think I saw any ambigious bits in the midas section.
Oh: I nearly forgot, are you interested in the Nintendo ROB? It has an old Sharp MCU that needs decapping. The toy is super expensive on ebay, so our best bet is someone willing to donate the pcb.

Got it, thanks. Yeah, if it's similar to the SM51x, and I can figure out how to dump all the pages of those, we could dump it electronically. Otherwise, if we can get a dead PCB, I can decap the chip. This one seems reasonably priced: http://www.ebay.com/itm/NINTENDO-DE...MES-AND-MOST-WRAPPINGS-AX9-/371262843039

Externally, it's the same pinout as the NES lockout chips, no testpin unfortunately.

tntell is emulated and playable =) That also includes the UK and French versions, Vocaid, and 6 external modules. http://www.datamath.org/ has scans of the overlays, though with a visible watermark.
