I have such flash cart. it have onboard TWO ROMs, marked as: ST 88844S M27256FI (i.e. - total 512kb??) On this cart now is flashed CDX (from Eidolon's Site). Is it possible to replace those two roms with anything bigger then 512kb (i.e. to flash at least Knuckes Chaotix 32x - 3mb or Star Wars Arcade 32x ~2,5mb (20Mbit))?? Thanks!
