It's not during the Level Select Screen, but the entire Project M that doesn't boot. When I enter the stage builder nothing happens, as if I hadn't inserted the SD card.
I used the .bat files that came with the download to move the P:M files, so I suposse that shouldn't be an issue
I'm having this exact same problem. I followed the steps exactly and I when I load brawl and go to the stage builder, nothing happens. Project M doesn't even open up.
Additional question, am I able to use to stages that require two different .rel files at the same time? Like if I have a STGFINAL_A that needs a PS2 rel and STGFINAL_B that needs a mushroom kingdom rel, how would that work?
EDIT: I managed to correct the problem. For the default project m 3.5 download, the private/wii/app/rsbe folder DOESN'T contain a pf/module folder. Put since I wanted to use custom stages, I have created one. So when i the pm to private.bat, it created and new folder line for private/wii/app/rsbe/st. By moving the st and pf folders manually to correct place, I fixed the issue.
HOWEVER, I now have an issue with game freezing upon selecting a stage lol. This seemed odd because all the other freeze issues I've read in this thread happens during a match, but mine freezes as soon as I select a stage. So will work on that later.
Second Edit: I discovered that this is related to my earlier question. It froze because I tried regular green hill zone with a palutena rel. Is there a work around for this or will I just have to be limited to stages having the same rel?
