I made it; it's CGC-sized. Should be a pretty simple edit in your preferred image editing program, if you want to attempt it. The various free art programs promoted here in the forums should all work just fine; I use Gimp.
The front, back and spine are all wider than a UGC. For the front, I think you can just crop it to the correct pixel size (trimming off some of the right side) to match the front of a UGC. You shouldn't lose any crucial detail.
For the back, you might need to crop the right side of that instead of the left side to avoid clipping any text off the left side (or just resize the whole back as required).
The spine is an easy edit: crop out the game logo and copy/paste it onto another UGC's spine (with Nintendo publisher logo, of course) to ensure it's the right size.
Glad you liked my work enough to use. I hope your UGC cover prints out great.
