Thanks for all your replies.
To be all clear, I know the general rules of WiiHacks. Second of all, I was talking about my backups. I am completely against piracy myself. I have all the games that I used to play on USBLoader in my possession, including Black Ops.
@Shift_Lock: Yes, I saw the part in guide. Thanks for the tip. I asked about the black ops thing because I read a rumour about that patch screwing up modchips.
My plan was to rent one of the games, since I don't have one of them, and copy it to keep it some longer, since the only store I know that isn't too far away, only rents Wii-games for 48 hours. Since I am pretty careful about my actions, I don't want to put too much pressure on it. When I would be done, I would not need the disc anymore. The fact that I am not really interested in one of the games, makes throwing it away easier.
Technically, yes, it is piracy. But I really don't know any other solution than buying a game that I would only use to get my Homebrew back. And at least I am not some person with 120 downloaded games on his hard disk.
I understand your discussion though, and all I can say is to keep up the good work. At least keep WiiHacks clean of piracy, nobody can stop the people that use the extremely helpful guides for that purpose.
