I'm aware that our covers are for UGCs and therefore will NOT fit in these cases, however, given their more ready availability for many folks, I'm sure that you could just do a bit of resizing and stretching without too much noticeable distortion of the image, hmm?
I'm wondering if someone could get the measurements for the Sega cases and perhaps create a tutorial on how to best adjust a UGC cover to fit a Sega box, for those who would want it. Doesn't seem too difficult.
