Can't get FP code 3.5.1 to work (SOLVED)

[N64killer]

Note that i am using a sdhc card. Okay so i have these 2 codes on my .gct
File patch code and sdhc extension. Gecko is reading my codes but not my mods so i asking what else do i need/what is the file structure for fpc to read mods?

for example: (D:)/private/wii/app/RSBE/pf/fighter/(character name)/Fit(character name)00.pac

Did you try Riivolution? It has less chance of random errors, and boots up faster, as well as faster and easier file placement; not to mention that it can be used for more than just Brawl.
If you have a Riivolution .gct and are trying to just plain use Gecko, you'll have to rename it; but I would recommend the alternative.

What region is your disc?

I should of mention that I wanted to use brawlex in the first post cause my sd card is already set up for using riivolution and I have read it doesn't work for brawlex because of the .xml file not reading certain files.
Hopefully that clears up my intentions

For BrawlEx and Riivolution, you need to use the Brawl Minus .xml, and also File Patch Code 3.5.1b, not 3.5.1. Remember that BrawlEx is only compatible with NTSC-U versions of the game.
