Ah, I forgot to mention that in the readme.
First of all, the names of the file :
White Link CSP
- PAL : RSBP01_888999f8_9.png
- NTSC : RSBE01_888999f8_9.png

And in the first post, I will add a little tutorial on replacing textures by new ones. That should help you for future replacements.

EDIT : Done.

Thank you!

Hello, I made a HD Fierce Deity Link CSS for a texture I downloaded, and I have no idea what to name it. It would go over white Link, and I would appreciate it if you could give me the string of letters that would be for white Link.
