Play custom stages with expansion stage pack

[yordic]

Hello, I played custom stages switching the default stages like 75m, skyworld... to peach castle 64, metal mario cave... but if I try to play with the expansion custom stages, like STGCUSTOM01.pac and put te custom_finaldestination.rel as st_custom01.rel file and play, the game stop when I selected at menu, but I can press HOME button and go at wii main menu.
I use to play the brawl minus mod, and put the "Phantom Wing's Stage Expansion Code 2.0" and "Eternal Yoshi's Maxed Out CSS".
Someone can help me?? What's wrong? thanks.
