Preferably NTSC-U, and with a logo on the spine; white spine if possible, as opposed to the black Dreamcast font.
-Ooga Booga
-Samba De Amigo
I've edited a ton of the covers on here so that the spines match eachother. I did them all using existing covers though, so I'm not certain I should upload them, as it might be sorta plagerizing. I have no idea how to use Photoshop, but I'm really good at editing in Paint, which is what I did with a ton of existing covers, unfortunately the aformentioned don't have covers on here at all, so I'm not able to just do a cut and paste job on those like I did the rest.
If I can help at all, please let me know!
