Could you tell us what you did or send us your STGRESULT.pac? :3
I saw in Ridley's cosmetic config that his ID for portraits and icons is 41 in decimal, so in the results pac it should go InfStock.411-418 right? I tried adding those into MiscData120 and all of his icons were still the same Toon Link icon in the results screen.

The ID for victory music is in SlotConfig, and I was pretty confident that SlotConfig3F and 40 belonged to Mewtwo and Roy... so I tried editing those and literally nothing changed in game.

Here is the link. However, you may need to edit Mario's stock icons to what were originally since I changed his costumes.

You add the stock images in MiscData120 named InfStc.411, InfStc.412...etc. Then go to MiscData110/AnmTexPat/InfStockface_TopN_0/stock_lambert87/Texture0. In there you have to make a new entry and name them Inf.Stc.411, InfStc. 412..etc just like the stock images. and make sure the frame index matches the number and underneath that the texture and palette should say Inf.Stc.411...Inf.Stc.412 etc

Hope this helps and I'm not sure if 3F and 40 are the slots for Mewtwo and Roy. It may be one of the other ones.

I also edited Ridley on the character select menu so that the announcer doesn't say anything and he roars like Bowser instead of saying "The fight is on" like Pit on the Wii remote. Do you want that as well?

I'll keep working on it. Did you find the solution to the result screen?

For Ridley's stock icons? Yeah I fixed that. If you're talking about the victory music of Roy and Mewtwo I have no clue what's going on there.

Thank you for the help. Now there's just the problem with Mewtwo and Roy's victory music

Hey been following this for awhile and finally got this. Nice work I've been waiting to use this for awhile. I notice a problem with Roy and Mewtwo. They have the wrong victory music. They are switched around. Can someone help me fix this? Also, Ridley doesn't have his stock icons in the results screen but I know how to fix that so no problem. Just the victory music for Mewtwo and Roy I need help with and if someone knows how to change Ridley's victory theme to match Metroid characters that would be helpful as well.
