You will need :
- A valid NTSC Melee iso file (make a backup just in case)
- A program called "DAT Texture Wizard" (download here : https://www.mediafire.com/file/ctm6scauxncb1wb/DAT_Texture_Wizard_-_v6.0_%28x64%29.zip/file)

1. Open DAT Texture Wizard --> Open Disc -> Select your Melee Iso
2. Go to Pl__.dat (Double-click) --> Select *Character* --> 
Right click on *PlFcRe.dat* --> Select "Import" -->
Choose the file PlFcRe (Akuma) : *Name of file*

The rest is optional : 
3. Get out of Pl__.dat --> Double Click on MnSlChr.USD (NOT .dat) -->
Right click on *MnSlChr.usd_0x270E40_9.png* --> Select "Import Texture(s)* -->
Replace with the file in the zip with the same name
4. Get out of MnSlChr.USD --> Double-click on IfAll.usd (NOT .dat) -->
Right click on *IfAll.usd_0xC72C0_8.png* --> Select "Import Texture(s)* -->
Replace with the file in the zip with the same name
5. Ctrl-S to save. It will create an ISO backup, 
as this uses a special model so that the back of Falco's jacket is asymmetrical 
(go here for the original creator that made this possible : https://ssbmtextures.com/characters/asymmetric-jacket-model/)
6. Open Dolphin and start the game!
