Set the config switches like this:
Next plug the GB Memory cartridge into the GB/GBA slot of the cartridge reader. Now you need to read the original content from the GB Memory cart to the sd card, both the flash that contains the menu and the mapping file. You'll find the Nintendo Power GB Memory menu under the Game Boy submenu.
You can use the GB Memory Binary Maker or the Game Boy Nintendo Power ROM Builder to combine multiple roms and the menu you dumped earlier into a bin and map file that can be flashed back to the GM Memory cart.
To reflash the GB Memory cart you need to first erase the flash, then blank check it to be sure it really was erased and then write the rom to the flash. You also need to write the new mapping file.
This file contains Unicode characters that might be confused with other characters. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.
