I used the codes that came with it which were
-Custom CSS (pre-done)
-Custom Random (pre-done)
-Independent Pokemon Engine v2
-Char ID Fix 2.1
-CSS Fix by Phantom Wings
-CSS Fix for ZSS/Shiek
-Regular Zelda Icon
-CSS Fixes for Giga and Company
Although, while the CSS works, and characters like Shiek and ZSS work fine without crashing, if I choose any of the 3 pokemon, the announcer calls out the name then promptly gives me the loud beep afterwards. e.g. Chariza-BEEEP.
EDIT: Thought maybe adding the alloys dont crash code would help. At first, it did! I chose Squirtle and Charizard fine without crashing. Then I chose Ivysau-BEEEP. After a reset I tried again and I was back to square one as it crashed if I chose the others.

EDIT2: Okay maybe it did help. It still crashes upon selection, but instead of it crashing 100% of the time upon selection, it's like a 25%. Sometimes, it'll also be a delayed crash, where it'll actually say the full name, CHARIZARD, then like 1 second later it crashes, instead of interrupting the name like it first did. With this delayed crashing, I also tried quickly choosing Charizard and going to the SSS quickly but it'll crash not too long into the SSS.
