Instructions
Download a Game Boy ROM conversion program from one of the links provided below. Install the program, and make a note of where the program file (identified by an .exe extension) is saved.
Connect your Flash Advance Linker or similar device to your computer. These devices most often simply plug directly into a USB port.
Insert the Game Boy cartridge you want to convert into the Linker.
Start the conversion software. Select "Convert" from the File menu (this will be available in all three pieces of software listed below), and choose a location to save the ROM file.
Click OK, and wait for the program to finish. Once it is done, the ROM will be saved with a ".gba" file extension. You now can play this file on an emulator on your PC or simply keep it for backup.
