There are some ways to do so.. if you want to edit the actual ISO you can use Trucha signer. Notice though, that editing a single file will invalidate the signatures of the ISO and thus you'd need major modifications done to your Wii - downgrading IOS files and whatever - to play the game. A more elegant way would be to use Riivolution, which you can also use with your original disc (and only with it).
Riivolution can forward calls the game is doing to an SD card - so instead of opening the file from the disc, if will be forwarded to the SD card and open a harmless file there. That's a recommended way by me, it saves you from burning a disc or using backup loaders (unless your Wii is hardware modded).
Please note: no support on how to run a backup ISO, if you do not have an original, do not expect to get help here, Riivolution is the recommended way for what you plan to do!
Thank you, I'll give it a try
I'll use the safer Riivolution one, gotta get me an SD card first though, but I was planning on getting 1 anyway.
Trucha Signer and Wii Scrubber are working ISO editing tools.
Btw. what´s the file with the banlist?
I´m also interested in it...
I'm not sure yet, but I found a file called "limit201003.bin"... which looks alot like "limit year 2010 3d month": March 2010 banlist! However, it'll likely take a few days until I can tell you if it's really true, depending on when I have an SD card.
According to what I used to find this file, it's in Disc -> Partition 1 -> Duel -> Engine -> Bin16. Don't know how Riivolution or Trucha Signer explore the disc/SD card, though.
Say, since we're talking about this anyway, could you take a look at Disc -> Partition 1 -> Duel -> Engine -> Deck? It stores all decks, which is more than the amount of recipes I have. Perhaps you can do something with that for a cheat that really unlocks all: I'm still not sure if Skiller just created his cheat with my unlocked deck recipes, or if he really created an "all recipes" cheat (I didn't get a reply). Would be awesome if I could finally see ALL those deckfiles
(I know I can use Riivolution to swap deck files around, but I don't know which are the ones I don't have, of course).
