Black red Falco
What you see is what you get
1. Download and unzip the file
2. Open up DTW and open the ISO you want to change (whether it be 20xx or a melee copy)
3. Scroll down to the stage/character list, and then highlight the stage/character you're looking to replace by clicking once on it.
4. Click 'Import' on the right side of the window.
5. Find the file you downloaded in step #1 and open it
6. The file is replaced, now just do Ctrl+S or go to the top left and select 'File>Save (CTRL-S)'
7. Now just load up the game and the texture should show up ヽ ╭ ° ͜ʖ͡°╮ﾉ
