will the am29f032b-90sc work for a snes reproduction. Currently i use
AMD AM29F032B-75EC and it works fine. But i might be able to get the other one cheaper.

Any advice?

any speed of the 29F032 will be fine. the lower the number, the faster it is. The SNES cannot access it as fast as the limit of either one, so anything lower than say, 150 would work under all circumstances.

Thank you!
