Just make the iso with DiscEx as usual, then edit the files with any Hex editor. At the very top of the file you'll see the game ID along with the title "Sample Game Name" which you can just overwrite with the ID and title of your choice. WiiTDB's ids for them are GGPE01 for GP and GGPE02 for GP 2, I believe those are also the ids that the leaked releases used judging by the info there. Either way it works great for separating them in GX and making them compatible with Wiinertags.How to do so?
Thanks for the help man and I can use any hex editor or do you recommend one?
