Not sure where to place this question, but since we're on the subject of texture hacking, I think this may be appropriate. If the creator sees this, I need to ask, did you use a different FitPeach file than the one provided by Brawl+? That might be the reason we have issues with lock-up when trying to select your model (I'd love to see it in action).
Try asking the creator first. If not him/her go to the help thread. This isn't a help thread.
I'm using the FitPeach that's available at the NTSC-U download linked to in the BrawlVault resources.
And aside from that, both Verans are made with the same FitPeach as well, and there have been no problems with those.
I have noticed while making my hacks that occasionally they'll freeze the CSS, but I always just go back to my computer and re-save them in BrawlBox, then delete the old files from my SD card and copy the re-saved ones in.
