Just a quick question for all those who deal in making reproduction carts. What is the fastest eprom chip that the snes can handle? The 200 ns chips are impossible to find and 120s and 150s are getting increasingly more rare. Are the 100 ns chips ok to use? What about the ones in the 80-90 ns range? I can't seem to find any definitive information on what constitutes "too fast" as far as the chip speed is concerned...
