I have a s3-pmario.gcm and need to burn it to dvd and play it, I don't even know where to start. Please don't tell me to google it as I found this site after spending hours on google...
Last system I used with backups was Dream Cast and you just threw in a boot CD, and when it was done loading, you threw in your backed up copy and p00f. By the looks of it you can't do it with Game Cube. So my options are: Get a modem Mod the Game Cube Get a memory card ?
Go with a mod chip. Its much faster and much cheaper. I would go with the xeno gc if you want to keep costs down. I ordered mine from foundmy.com
