12/15/23 - It has come to our attention that this specific batch of carts are currently not compatible with GB Operator. Epilogue is working on a solution to make this compatible. Updates to come soon.

This Game Boy Flash Cartridge has 512KB of memory and was designed by Ferrante Crafts. Flash your own game to it and play right away!


  • Supports ROMs of up to 512KB using MBC5
  • 512KB of ROM flash memory, no RTC, RAM or battery. This means things like Pokémon or LSDJ will not work.
  • Can be used for games created with GB Studio, as long as they are at most 512KB and do not need saving.
  • Works on every game boy system which can play original game boy games (Original, Pocket, Color, Advance and Advance SP, etc.)
  • You can flash and reflash as often as you want. Currently only supports GBxCart RW. GB Operator may be compatible soon.
  • Settings for GBxCart RW when using FlashGBX would be: Ferrante Crafts cart 512KB
  • Comes pre-flashed with a game boy test rom, to make sure all cartridges are working.


  • 1x 512KB Flash Cartridge


  • Coming Soon

I love this flash cart.

I use this to test my homebrew games I make in GB Studio, and they're flawless, and fit nice and firm into the Gameboy. Got it on sale, and we'll worth it!

Does not work with GB Operator

The GB Operator recognizes the cartridge as 32 KB instead of 512 KB and is not able to be written to.


oh of the best cartridge reader os far. sure I can't save Pokemon games but add some custom software. works like a charm. recommend

gameboy color
Never worked correctly.

Cart crashes soon after powering up. failed after three flash attempts. Now un-responsive. Would not recomend.

Thanks for your review. There are several reasons this could be happening and we would be happy to troubleshoot with you. Please reach out to so we may do so.
