5/5

Just received my GBxCart RW v1.3 from AU to UK with no issues.
Really easy to use, simple user friendly interface to back up all your GB/GBA games + saves and RW carts.
Absolutely love it – highly recommended.

Excellent product. This is the cheapest GB/GBC/GBA cartridge reader I could find and it works perfectly for backing up ROMs and save games from cartridges and writing save games to cartridges.

Cheers.

(Check if your cart matches by checking board pictures here)

Carts that don’t work are any chips labelled with “6600” or “40xxx”

Please note: If your game saves to an EEPROM then it won’t work on any of these carts unless you patch it to use SRAM. If the cart you have doesn’t have a spot for a battery, then you will need to patch that game to save back to the flash. Check what save type your game uses here.
