I'm starting to get a bit of a Naomi arcade collection going now but was stumped as to how to store the actual cartridges. So today I decided to make my own cases which are actually pretty solid.
The main case is a standard B5 size file holder approximately 4.5cm deep. The covers are bubble jet printed although a home ink jet printer will do just as good a job. I've also laminated the art work for reasons you'll find out soon.
First you need to layer a double layer of bubble wrap on the bottom of the case using good quality double sided tape.
Next you need to do the top of the case. I decided it would be better to place the cover art inside the case. This way it saves it from any damage. Place double sided tape around the edge of your cover art. This is why I laminated them. If you make a mistake you can just remove the tape and start again. Also laminating the image will preserve the ink quality from fading. After placing the tape around the image, fit it in to the top of the B5 case.
Now you need to protect the top of the case, so again lay a double layer of bubble wrap over the cover you just fitted using spray glue or double sided tape.
Now your cartridge will sit snug as a bug. Free from knocks, slips and what have you. The cartridges are also locked in to place by the bubble wrap so they won't side about in the case.
OK, now we need a spine. Again this will be fitted to the inside of the case. But because the case splits when opening you only need to attach the spine to the lower part of the case with double sided tape as shown by the red marks on the photo below.
And here we have the finished product.
