I uploaded the TMNT ROM dump transcribed from the die shot. As expected, the one typed in from the patent had a bunch of errors, but comparing the two, I'm confident of the file. The only differences between the dumped file and the patent file are the 64th byte of each page. I guess they didn't license TI's method of detecting all 1s and forcing 0s to get all 64 counts.

I also posted the melody ROM. It's the same except that the patent ends with 5 $FFs, but the die has $00s.


I don't have a Contra to decap, but the printout in the patent is pretty sharp. I'll double-check what I typed in previously.
