I've also checked one I had in the backlog: cd2708. To freshen your memory: it was the arduous-to-transcribe Speak & Math decap from Siliconpr0n.

One error: offset $3A8, change $A0 to $AF.
Also, from reading the disasm, I conclude there's one under the smudge too: offset $108, change $14 to $15.

It looks like it works in MESS now. I'll update the driver in a bit. Did you have more decaps planned for TI Speak stuff?
