I just noticed that all of your covers are TMNT4 LOL!
Why don't you use the SNS and barcodes for each title? Seems odd that you put that data there, but then don't use it for each game. I mean, don't get me wrong, I'm not trying to figure out if it's 73% or 80% recylced material for my N64 covers, but the SNS/barcodes seem like they should be correct since they are present in the template.
Earthbound looks killer by the way.
