Looks like I need to get some DVD-9 discs, SSBB-PAL, and a way to dump my Mario Kart. I'll let you know how it goes.
I don't know if anything was installed before. I got it in the state it was in and haven't been able to get it to boot until now.
Get smash stack to load, do my softmod guide. If the system menu still does not load, which it probably will not, burn Nintendo Backup(250).zip and load it via neogamma from the HBC. Load the HBC via priiloader. Don't skip the nand backup in chapter 1, and if your lucky you'll be able to install boot2 bootmii. Load the N backup disc and do the delete all function.
If that does not help, probably need to build a new nand.bin with the nand.bin builder by giantpune.
