* '''Snes9X:''' Under "File/Load Multi Cart...", choose the base game for "Slot A" and the expansion pack for "Slot B", and then the BS-X BIOS file. The combined game variant should open. Most Memory Pack games should work this way but some are unavailableunemulated for various reasons - it's one of the last overlooked areas in SNES emulation after all.* '''bsnes-sx2:''' Under "File/Load Slotted BS-X Cartridge". However, due to how the emulator doesn't have a "Show files from all extensions" option, and an oversight during development, the expansion pack file can't be selected. Due to this, current versions can't go in-game.
