Hi, After playing Mario & Sonic on the winter olympics for a while from CFG loader, I went to the system menu from the game. Instead of acctually showing the menu it said the "system files are corrupt" I have bootmii v2 and no Nand backup... I can still enter the HBC. I'm on 4.1 E I installed a fresh System menu but it did'nt help. I installed an unstubbed ios 60 but it did'nt help. Any ideas?
