Just got around to trying this app out and it's great and really easy to use. Had to find 2 dll's for it (libeay32.dll mentioned in this post & MSVCR71.dll) but adding the keys was no problem using your other app key grabber.
All I wanted to do was hack a One Piece 1 save file, so made a save and wrote down some values, played it a little and changed they values. I compared both save and searched for the strings and found everytihng easily so was able to modify health, SP, items, characters and lots more. Copying the save back to the wii worked no problem but, when launching the game it complains of the data being corrupt.
When you extract one piece you get the banner, and a folder called "share" inside this folder is 4 .bin files. user00.bin, user01.bin, user02.bin & system.bin. Changing anything in them results in corrupt, so is there any other apps out that can help with my problem ? I'm thinking that the system.bin verifies the content of the user0#.bins, but don't know where to start tbh (what is calculated and stored where).
I'm sure there will be answers floating about somewhere.
Reading the topic some people mentioned emu>vc & vc>emu ...... that would be cool if someone gets it all figured out too.
Great stuff WiiCrazy
