What was the status of the Coleco Frogger game? I can't remember if you were able to figure out dumping it or not...
I finally dug up a Gakken Frogger, and it's the same Konami chip, but with a different die code: M58846-700P (You mentioned 'P's once before, is that possibly a protected chip, or just a coincidence on this one?) The VFD is a CP5084 GLR, and is slightly different than Coleco's, but mostly in the art style of the sprites.
Found a Rockwell B9001-13 in Mattel's Horoscope Computer. Where any of the earlier Mattel LED games (like Battlestar Galactica) dumpable, or was decapping used for that?
Yes I dumped it. The VFD artwork and the dump should be sitting in a /coleco frogger/ dir in the usual place. Hmm just checked. the ROM dump is not in there. wonder how it got left out.
I just uploaded the ROM dump and the disassembly of it. Interestingly they are using 3 instructions that are not documented. I know what two of them are- they appear to be a left and right rotate. I documented them in the disasm.
I know they are rotates because the code "makes perfect sense" for them to be that- I reversed the VFD scanning/display and button reading part.
Yes I can dump those; in this case the P does not mean protected as far as I know. the 701 I dumped was a P version too.
As for the rockwell chip I have no clue. if it's an MM7x it's probably dumpable; this would be tellable via the pinout. An NEC 550, let's see... Yeah looks like it's possibly dumpable; there is a test pin on it. This seems to be the same/similar to the 557 I have here I was going to try to dump.
