I dont know what to do with this .rel file

[mattxXx]

The programs I've been using are Dolphin and WII Scrubber. For some characters its easy, I just replace the files I see in WII Scrubber with the corresponding custom files which usually consist of 3 or 4 .pac and .pcs files. However, the character I want has a few .pac and .pcs files, but it also has a .rel file. I don't know what to do with this .rel file since there isn't a matching file the shows up in WII Scrubber. The character is used on olimar and just replacing the .pac and .pcs files without using the .rel file results in dolphin crashing after olimar and a stage is chosen. Any help is greatly appreciated.

replace ft_olimar.rel in the module folder.
