Replace the MiscData[30] in the char_bust_tex_lz77 in your sc_selcharacter.pac with the included MiscData[30]. Make sure you use BrawlBox v0.71.

In MiscData[90] in your sc_selcharacter.pac, import the included InfStc.3XX.png files under the CI4 format (or use the CMPR format if you want to save some file size).

In your STGRESULT.pac, go to MiscData[120] and do the same thing you did for MiscData[90] in your sc_selcharacter.pac.

In MiscData[40] of your sc_selmap.pac do the same thing you did for MiscData[90] in your sc_selcharacter.pac.

The MenSelchrFaceB.0XX.png files are for manual insertion if you happen to come across issues with the provided files.
