Hey everyone. With the recent releases of Ghostbusters and Indiana Jones only working with rev13a, I considered a "fix". Since rev13a has some of its own problems (like forcing a reboot every time a game is loaded twice), I figured I could do this: load almost every game with cIOS rev10, any problematic games or games that require a microphone can use cIOS rev13a. I can't seem to figure this out though. I am using USBLoader GX and it gives you the option to boot certain games with certain IOSes. I have them all set to 249 (which is cIOS rev10) and the few unworking games I told to use 222. For 222, I tried Hermes' installer but Ghostbusters wouldn't boot. So I then loaded up cIOS rev13a, and when it asks you to use 249, I told it to use 222 instead. I figured this would make cIOS rev13a on 222, cIOS rev10 on 249, and in USBLoader GX, I could tell it to use 249 for everything, and set specific games to use 222. This doesn't work at all and I'm not sure why. Is 222 reserved only for Hermes' or something? Was I an idiot for installing Waninkoko's cIOS to 222? I thought what I was trying to do made sense but it's not working. Thanks to anyone who can help!!
