I'd love to get this open sourced and actually work on it myself, but i doubt it will happen. The author said he was only doing that last patch.
Also about the iso, you don't have to have exact matches, the one i had didn't match exactly, however it worked no problems. I have a real copy and a iso copy from demonoid.com that both work. Yes, I'm dumb I buy games lol.
Did you follow the directions word for word, also WIIscrubber did it for me so i know that's not the issue. It's either you messed up what it told you to do, or your iso needs to be cleaned or redownloaded. There's another program called trucha something, that works when wiiscrubber doesnt. research alternative iso editors for WII.
