CSS hacks freeze whenever I go to the stage selection screen

[TempesT]

I've been trying to get CSS mods to work for quite some time now. I have read ASF1nk's guide and made sure that I have all the necessary codes applied, and I have correctly placed the common5.pac files in the proper areas of the SD card. I have tried several CSS mods that enable the useage of Zero Suit and the PT Pokemon as their own characters and with all these CSS's, I keep having the same problem of the game freezing once I go to the stage selection screen.

For some context, I am running brawl minus, with several custom CSPs, Brstms, and character and stage textures,  and .rel files. If anyone has any idea what's going on, any help would be appreciated.  

[Edit] Upon further inspection, I've learned that the game will freeze as long as I have the codes on. I took the CSS of and loaded the game with the same codes (including the ones recommended by ASF1nk) and the game froze anyway. I guess that means that there is definitely somethign wrong with the codes.
