ok, on a somewhat related topic, for the sake of not creating a whole new one, i decided to bump this.....
i have 4 custom stages from project M, fountain of dreams, yoshi's island, sse jungle and the ssb64 caverns.... they replace yoshi's island melee, distant planet and mushroomy kingdom, respectively.
i open my common5.pac, and navigate to sc_selmap_en/MiscData80/Textures so i can change the thumbnails and previews for the stages on the stage select screen. simple image replacement, i've done it for the character select screen plenty. so i replace the 4 stages with the new thumbnails and such... but the game freezes as soon as i get to the stage select screen. i don't get why it's freezing, it works fine when i use it for project M. just freezes for regular brawl. is it more than a simple image swap?
