Okay, I know there are similar thread to this, but this is kind of a weird situation. So right now I'm using BrawlBox and Dolphin for SSBB (I'm learning how to hack the bones on the vertices themselves), and replacing certain files, since figuring out exactly how certain bones are actually affected in-game is a very tedious process. What makes the whole process even more tedious is the fact that every time I want to to see the results, I need to take the file I altered, put it in the RSBE01 folder that was extracted from the ISO, then recompile the folder into an ISO image; for that, I use a program called WiiBaFu since QTWitGUI/Wit give me a hard time. Now, the number of files I replace each time is negligible (maybe four of five files) that are in constant need of testing each time I alter them, and having to recompile the ISO image is very, very tedious as I pointed out earlier. What I want to know is, are there programs that I can that allow me to replace files in the ISO image on-the-fly, without having to make a new ISO image? To sum up: - I use both Dolphin and BrawlBox to alter the FitMotionPac, etc files - The files I change are in constant need of adjusting (especially when I try to figure out X, Y and Z axis) - I need to find a way to replace files on-the-fly in the ISO without having to recompile when I only change a few files and not all of them Is this remotely possible to do? I know that Brawl related hacking would belong on the Brawl Vault/Kitty Corp forums, but since my request is about the ISO itself and how to replace the files in the RSBE01 folders, I'm asking the question here at GBATemp. Any suggestions on how to get this done?
