Thanks for the replies everyone.
Randoms happen a lot when your CSS value in your CSS code does not match a FighterConfig file's number in your BrawEX folder
Also when 29 is not the last integers in order in your CSScode
Here's the last line in my CSS code: 0A23193F 29000000
I don't think I did it wrong but if I did please tell me.
It also happens when the bx_fighter.rel file isn't loaded for some reason.
I put it in private/wii/app/RSBE/pf/Module
Did you make sure to use the files from BrawlEx v1.1.2.0 and not BrawlEx v1.1.2.1? That was my problem at first. Try this: download BrawlEx v1.1.2.1 and copy the bx_fighter.rel file from the core files folder and put it in your module folder on your sd card under pf/module
I used the core files from BrawlEx v1.1.2.0. And now I tried BrawlEx v1.1.2.1, and it didn't solve my problem :/.
