RE: 65C02 timing

Actually, you should be able to drop a 65802 right into a 6502 game and it
should work fine. Both the 802 and the 816 start up in 6502 mode. You have
to set a flag to get it into 16 bit mode (done by setting the carry and
using an instruction that transfers the carry bit into the mode bit).

I've thought about using the 65802, but I cant find a source for them.

"Kinda like Al's 65816 idea..."

having programmed both, I certainly prefer the 816. The 802's
were pin compatible with the 65c02's, but it sort of sounds
like they're out of production.

some patching would probably be required to get existing games
to run due to instruction differences, though.
