It starts off with 6502 code and has lots of graphics.
I wrote the data in little-endian format. I'll have to locate the code I used to dump the Vtech laptop ROM, but I'm guessing I wrote that as big-endian. Oops, got confused with the vsmile stuff I dumped for Klaus. I didn't dump the vtech laptop ROM.
interesting, so this one IS still 6502, but EU3A12 does not appear to be.
my latest pull request on github adds the laptop as non-working anyway, if somebody wants to poke around trying to find out what the CPU is derived from there, it might be something obvious I missed.
