Good to see progress is happening on this pack! I've been struggling with adding a clone to it, but I assumed it might be something that would be fixed in the next release. Unfortunately this has not been the case, and I'm still having trouble. It must be something I'm doing wrong, but I've been following a ton of Brawlex tutorials. Is there some special method we need to use to add clones that isn't part of regular Brawlex? Has anybody using this pack actually added anyone extra beyond Pichu, Young Link, and the others already included?
My process has mostly been: set up new clone spot (#44) using Sammi Husky's clone tool, then I copy the fighter's module into the module folder, give it the correct id (44) in section 8 and change its module ID to something unusued (the last build I used 148, but this one I used 149). Then I add 44 right before random in the cssroster.dat and create a fighter folder using all stock files from the Brawl ISO, naming the folder and all files within it after what I've edited the fighterconfig file to be named. I think that covers just about everything. I've not tried editing any cosmetics yet, just trying to get a new clone to work. Lately I've been getting a freeze after selecting it on the CSS, whereas before I was getting it on the character's failed entrance animation.
Again, sorry if this is more of a general Brawlex question, but I just noticed the clone's IDs in the clone tool don't really match up with the numbers on their Brawlex config files, so I assumed it was something specific to this pack. Also just interested in case others who've tried it have been able to make it work, so I can narrow the problem down to something I'm doing.
I added Lucina without issue on 0.5. The PSA you're using might just be incompatible with Project M.
