Any BPS, UPS, IPS or xdelta patch for Emerald, FireRed, LeafGreen, Ruby or Sapphire. It is applied on this device to your own clean base ROM. Nothing is uploaded; the patched game is only checked and played here.

Remember base ROMs on this device

Base ROMs stay on this device. In a room only the host chooses one, and only the patched game is shared.

The scan decides what the patched game supports: a partner on your map, co-op battles and save files. A game the scan does not recognize still plays solo.
