Ah, Grasshopper, but do you *need* dual ported RAM? Perhaps you should redesign to avoid it. (Latches and buffers and hi-Z, oh my!) Of course, real hackers program the 2600 using the hack-n-burn method. :) It only took me a few hours of work to convert that old 8080 assembler I wrote in PL/I back in my college days to a 6502 assembler written in Turbo Pascal, and now all is nirvana. Sort of. I'm still eagerly awaiting the Starpath documentation, though. Hmm, that sounds like an ObHack... better cross-post this.
