Return to Question

This week I am repairing an old Game Gear, suffering from bad video memory. The original IC is a HM65256BLFP-10T: an asynchronous Pseudo-Static 8-bit 32k-word RAM with an access time of 100ns.

I would like to replace it with a similar memory, but I do not understand some of the terminology regarding this type of ICs. Does it matter if my new RAM is rated as a CMOS Static RAM? Can I replace a PseudoSRAM with an SRAM?. Is there any risk (damaging other components or modifying the game experience in any way) on choosing a memory with more capacity or less access time?

I have been reading he datasheets of some ICs. Would either Hitachi HM62256BLFP or Sony CXK58257AM do the job?
