EDIT: I've just tried with my originals games, and they are also not working... I'm post here because I'm tired of trying and frustrated with my Wii. I really need help this time. First, my Wii wasnt reading two games: Resident Evil DC and Marines Something. But all the other games were working fine, including recenet ones like No More Heroes 2, Sky Crawlers, Ju-On: The Grudge, etc. But the console just couldn't recognize the discs of RE and Marines. My Wii was on 3.2U. Ok. So, in order to run those 2 games, I installed IOS 222, 223, 249, and after IOS56, IOS61, IOS57, etc. Tried some loaders like Neogamma, etc. Also tried serveral DVD-R brands, but no success. Then I decided to install the 4.2U firmware using v4.2 Safe Firmware Updater - http://gbatemp.net/index.php?showtopic=184057 -. It worked and I got 4.2U. But I couldn't run backups anymore ("cannot recognize disc" error). But, according to that topic, I should use DOP-IOS to trucha patch my IOS7O to get my backups working. Then I downloaded the DOP-IOS. Accidentaly I truched the IOS36 (I don't know it it has some kind of influence), and after I did the IOS70. Now the HomeBrew Channel is upside down and my Wii still cannot read backups. My question is: what can I do in this situation? I have BootMii with a backup from my 3.2U system, so I think that I can go back, right? (yeah, that's another question) But I would like to keep the 4.2U firmware and get everything working again. Thanks in advance.
