I guess it depends on whether the game cartridges only use it for storing savegames, or as actual additional RAM.

- rbanffy 2y agoYes. It'd be a problem for running code directly from it - it'd be better to cache it to DRAM so that all reads would come from DRAM and only writes would make it to FE-RAM. IIRC, it was a common trick with 286 and 386 PCs, because BIOS ROMs were 8-bit wide and shadowing the BIOS in RAM made it much faster.
