Whenever I try to make one, everything is fine. But when I test them in game, they freeze my Wii DX.
And I follow every single step to avoid freezing, but it always freezes.
I am a Riivolution user and I use NTSC-U.

I want CSSs and CSPs of:
Shadow over Donkey Kong.
Master Chief over Snake.
Arbiter over Ganondorf.
Mephiles over Jiggs.
Silver over Diddy.
T-Rex over Yoshi.
Tabuu over Dedede.
Roy over Mr G&W.

I always try to do them, but when I test them on my Wii, it always freezes no matter what I do. I tried using codes, but I always have that problem.

I have a serious problem when going to the CSS.
My CSS has still no changes and I'm not using any CSS code.
But in-game, my CSS shows 2 "new" randoms. Whenever I select one, the game freezes.
I need help to fix this. I hate how my game freezes at the CSS even before I can select my character.
I am a Riivolution user.
I need help, please someone reply.
