Years ago I purchased a black PAL Gamecube, modded with a qoob Pro. It also game with a few burned games, which I tried booting back then and it worked flawlessly. Today I hooked the console up again to play some Gauntlet. By instinct I burned the image on a CD and tried booting it, which didnt work (qoob told me he can't read the disc). Out of curiosity I tried booting up one of the old games that game with the console and the same thing happened. I did noticed though, that the guy I bought the console from didn't burn the image on a cd, but rather burnt the cd as a "data dvd" with the image file (iso) on it. Here's where it gets weird. I fiddled around with the old game and the qoob bios, and at some point, by pressing "B", through the main menu an option popped up that let me allow to browse the contents of the DVD. The image file of the game showed up (ikura), I was able to select it, boot it, and the game started. After that I reburned Gauntlet the same way (data disc, imagefile on dvd as just a file) and tried to replicate the whole browsing the DVD contents thing, but couldn't. Even using the old game I couldn't reproduce it. The option just wouldn't show up anymore at all. tl;dr: using qoob pro 1.3c, I was able to browse the contents of a DVD with an imagefile on it (iso), select the image and boot the game that way. Was not able to reproduce the same thing with different game (but same burning method) or same game. I have no idea what is happening here, and real sources for information about the qoob are rather rare. Hope anyone here can help!
