Well, what I want to do is add some cheatcodes to my games on my external HDD. Specifically, We Love Katamari, PAL version. I have Swap Magic 3.8 CODER, I have an Action Replay MAX, I have a Gameshark, and I have a code breaker. I can use any of those to do it. I tried using CODER to set the cheats, and then boot Swap Magic 3.6, so I could load the SMBOOT1.elf(usbadv.). It didn't work and went to a black screen. I'm assuming this might have something to do with the mastercode, because the disc isn't really Katamari. Its swap magic. So I guess what I'm asking is...Does Swap Magic have a mastercode, and how could I use this to get my cheats to work with the games on my External Hard Drive.
