How it works
Test your ROM
The tester reads your ROM's header, tells you if it fits our cart, and lets you play it as the cart would. Your file never leaves your device.
Order your carts
Upload the ROM that passed, add your label and choose how many. Opening soon.
We flash and ship
We check every game before we charge you, then flash, label and play each cart before it ships.
What you'll be able to order
Carts with your game
A new MBC5 cartridge with your ROM flashed on and played through before it ships.
Your label
Send your label art and see it on a cartridge before you order.
Small runs
One cart for your shelf, or a batch for testers, jam entries or backers.
Shell, box and manual
Pick a shell color, and add a box and printed manual if you want the full set.

Questions
- Which games can go on a cart?
- Original games you made or have the rights to, built with GB Studio, GBDK, RGBDS or anything else. No commercial games, backups, ROM hacks or fan games.
- My ROM isn't MBC5. Can it still work?
- Often. Games with no mapper run as they are, and MBC1 and MBC3 games usually need a test or a quick rebuild. The tester tells you which.
- When can I order?
- Soon. Leave your email and we'll write once when ordering opens.
- When am I charged?
- Only after we've checked your game. If it can't go on our cart, the hold on your card is released and you pay nothing.
