Using the GBxCart

The GBxCart is a wonderful device that makes flashing and dumping Game Boy games very easy and streamlined, especially when paired with the FlashGBX software by Lesserkuma. Check out all the information at the GBxCart website.

These instructions were written with the FlashGBX v4.3 software, with GBxCart v1.4 firmware. Honestly, these steps are mostly self-explanatory. But I'll go through them anyway.

Step 1: Connect to the GBxCart, and plug in your cart

You should click "connect" at the bottom right corner to connect to your GBxCart. Then, select Game Boy mode and click "Refresh" to read your cartridge. If it's a brand new cartridge, you will see something like this:

Step 2: Write your game

Click "Write ROM" and the GBxCart will detect what kind of cartridge you're using. With my MBC5 Type A with SRAM cartridges, I get this screen:

Now, select your ROM file and let the GBxCart program it. When you're done, your game should show up in the Game Boy Cartridge Information panel on the left.

Step 3: Write your save file

If you have save data you wish to write to the cartridge, select "Write Save Data" and "Restore Save Data." Then navigate to the save data file, and select it to load it onto the cartridge.

Step 4: Write the next game (if using a multicart)

If you are using one of my multicarts, then swap games by either pressing the button on the cartridge, or pressing "Refresh" if your game changes with resetting the console. Then repeat steps 2 and 3 as needed to fill up the other game slots.
