This format is used by ROM hacks, and is supported by at least Snes9x and bsnes. It's indicated by having a copy of the header at 0x400000 with a LoRom map mode. The removed check for map mode 0x22 triggered in S-DD1 games, but their memory layout is very different from ExLoRom. Their mapping is handled by `MapBsxMemoryPack` instead of the regular `RegisterHandlers` code anyway, so the setting of that flag had no effect other than what's reported in the log window, but it was removed to prevent future confusion.

(This is a slightly improved version of the patch I mentioned a while back on the snesdev discord.)
