Hey! Out of curiosity (and OCD): can I remove "Mothballed" IOSes (as marked in WiiBrew here)? I'm running latest FW 4.0, with BootMii as boot2 and with NAND backup made (safety net). I don't know if deleting them with ATD would or wouldn't free any memory blocks, but if the Wii still works 100% after deleting them all, I'd still like to do it. Anyway... let me know what you think. Thanks!
