Hacking Kirby Air Ride Dios Mios

[Flurry]

So Kirby Air Ride gives me a black screen when I try to boot it with CFG USB Loader or USB Loader GX.
The Dios Mios screen pops up and does it's thing, but nothing happens after that.
I have DM 2.9 Lite installed. Installed with IOS236
The iso was fixed with DiscEX through DMLizard. Put on SD card in games folder.

Any help? My Kirby Air Ride disc has "Disc cannot be read" now, and it makes me sad :'(
