Woaw it's been long since the last time I posted. YouTube purged all of the videos at some point…not that it matters anymore now that my old tutorial won't work on Dolphin 5.0. Head over to my main post for the new method.
There's also two tools I recommend for the sake of load times caused by custom textures:
oxipng v1.0.4 and
JPEG & PNG Stripper
Both of these tools help optimize PNG textures by shrinking their file byte size without any quality loss.
Drag ‘n’ drop all
custom textures onto the
oxipng.exe, then drag ‘n’ drop them on the
Stripper.exe for even smaller file size.
Old mods are now updated in my previous posts!
