I don't have a huge collection of CPS2 carts but I have enough where they are all stuffed inside a couple of bins sitting out in my arcade room. While they are sort of organized, I want to be able to access them with ease and I wasn't sure the best cost effective way to do this. That's when I found the "CPS2 Kitbox Label Guide" by dubdubdub.
Basically, you make custom labels for each board, print them out, then slap then on a Uline box, finally, cut down your foam and glue it down inside of the box. What you end up with is a nice, clean, organized box that can sit on a shelf for easy access.
The easy part was to make all of my labels, then place them all on a sheet and have them printed out 6 at a time. Here's the template I made if you want to print up 6 at a time. After having them printed out at FedEx Office, I used their paper trimmer and cut out each label, because I'm cheap and I didn't want them to over charge me to cut these out.
I made up my labels then ordered my boxes and foam. Sadly, the price of the 1" foam increased $5 to $19.99 per yard and is a pain in the ass to cut with a razor blade. Next batch of foam, I will actually follow dubdubdub's suggestion of using a sharp bread knife. So for now, I only have two boxes 100% completed with 13 more to go. So every payday, I'll probably just pick up two order of foam and slowly knock these out 4 at a time every par period.
All in all, I do like having my CPS2 carts easily accessible and they do look nice on a shelf. I'll have to adjust the foam for my Hyper Street Fighter because it is a little wider and shorter than the standard B cart but all in all, I'm happy. Once I'm done with this project, I'll probably do something similar with my bare arcade PCB. If you have any suggestions, comment on this post. It would be appreciated.
