Yeah, I have it. It's a cracked Code-Breaker you can move from a USB Device to the Memory Card, and it'll function as a normal CB. I heard you can't just launch it while it's on the USB device, because it'll freeze, you'll have to copy it to your memory card. Assuming, you have Free MC Boot, or something that launches .elf file.
Or....
I also heard that you could patch the CB iso, burn it, and allow it to run with ESR, or with a purchased game.
Either way, it requires something to launch a elf, or the ability to play burned discs.
