For the Brawl- stage in the Brawl pack, I'm going to include New Pork City. For the Brawl- version of the pack, I'm putting Frozen Pokemon Stadium 2 in its place (there'll already be two Yoshi's Islands, the original Melee one and the Brawl- version of it.)
By the way, the Brawl- pack won't have the 3 stages from fangames - I wanted room for the original Green Greens and Yoshi's Island as well as their Brawl- equivalents. I also put P:M Norfair in the Brawl- pack to fill that last slot, since Brawl-'s "Norfair" is actually Lavaville.
Hopefully the Brawl and Brawl- packs will be finished in the next couple of days! I'm going to use Alm5252's Mushroom Kingdom Melee in both.
EDIT: I made changes to the ISO Builder that make it work with my pack, but are generic enough to work with other things too. I posted them at GBATemp in
this post.I'm really sorry to say this but it still isn't working for me. Using Project M with all your custom stages and the character selection screen doesn't show all characters, nor can you see all of the stages from the stage selection screen.
