No worries, I’ll just move it to the proper section.
If I’m understanding right, you’re trying to use both patches, and the first one succeeds but not the other? They’re both based on the original, unedited North American p4 iso, so it wouldn’t recognize it after being modded the first time. To apply the second one you’ll probably have to use the mod compendium and use your once-patched iso as the input

Im trying my persona4_new_bgm.iso to install undub mod with mod compendium and running iso mod in pcsx2, then stuck after boot

Console said illegal format not afs

Oh yeah I should’ve mentioned, but when did you download the compendium? A day or two ago we updated it to fix a problem with the executable not always being patched at the end, hopefully redownloading it will help: https://shrinefox.com/?tool=modcompendium
