Thats why they are all listed as custom. I really don't like the different developer logos and little changes each developer made to the spine (ie: different color red stripes, white or silver "genesis" spine text, vastly different sizes for the developer logos and random little text added to the side. I put Sega on the spine of all of them because the game is made for Sega's system. The only reason i have the red stripe on the bottom front is because the artwork did not fit without something to make the canvas area smaller vertically. I meant to put a Capcom logo on the back of the SF2'SCE cover but i forgot.
So in short i wasn't trying to stay true to retail, i just wanted everything to look consistent lined up next to each other. For the future i can put the respective developer logo on the front and back but i'm going to keep the Sega logo on the spine.
