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.

5/5

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.

If you are looking to purchase a GB flash cart, most of the clone carts should work except for a couple of multi-cart ones. We make our own GB flash carts too, check out our shopWhile clone carts are supported, we can’t guarantee that clone carts will work, some may have slight differences in their assembly.

Carts that don’t work are any chips labelled with “6600” or “4050”

Please note: If your game saves to an EEPROM or Flash 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.
