Hacking How to load your 3d covers to work on the matrix theme and all the 3d

[5MLZ97]

Hi I'm a noob on doing these but I manage to put in my homebrew channel and my usb loader 1.5. So my question is how do I use 3d covers on the matrix theme and all the 3d theme? The problem I'm having is saying invalid .png after I push download all missing covers. The code that gives me is something like GEF3_wide.png but all the ones I see are the ones with 6 digits like AE3W86. Help please. And last I want to give props to everybody who came up with these idea. Keep up the good work.
