I play Project M via usb loader (I keep two versions - one is plain Brawl which loads project m changes from SD card for easy testing, the other has the project m changes in the iso) and I've been having trouble getting some Kid Goku skins work on Lucas. I've tried three and they all crash on both of my testing versions when the stage loads.

Skins:
'The official Kid Goku'
'Goku official (face fix)'
'Kid Goku (Dragon Ball)'

The weird thing is I swear the first one used to work. I just hadn't used it in ages and recently when I tried it appears to no longer work.

The first two skins are modifications of the same one, the third is a completely different goku skin and none of them work. I've tried other Lucas skins ('The Weird Masked Guy') on other slots and the same slot and they work fine. All three Goku skins come with just a .pcs, I've tried with and without a generated .pac and no difference. Still hangs after I select a stage.

Not sure what to do, nor how to diagnose a crash that is just freezing after I select a stage. I've opened the skins in Brawlbox and nothing seems amiss.

[SOLVED]
Adjusted compression of .pac to none, .pcs to ExtendedL7ZZ, re-encoded all textures from 512x512 to 256x256.
