Speaking of GB/GBC/GBA, I finished a project today:
So these are custom cassette cases I made using art found online and in many cases, made myself with a template (you will be surprised to learn, I'm sure, that no one on the internet has made a GBA Tony Hawk's Downhill Jam cassette lmao). Inside are my cartridges in these little folded up cardstock things that keep them from flapping around in there, getting damaged (I also cut out the spindle holder things in the case itself). The cassette holder is a $50 thing I found on Amazon, that my wife helped me stain (because while I can do many things, anything I can do is not actually useful - her talents are actually useful lol). Didn't stain the inside bits because it's kind of a pain and we didn't feel like it. This is mounted to the wall, so it simultaneously freed up shelf space, while also making it easier to take a game down, without having to gingerly Jenga the game I want out of the stack.
It was a huge pain though, as you can imagine. Even after creating/sourcing the art, they then had to be printed, cut out, folded, and put into each cassette case, with the cardboard insert cut out, folded, and fit in there as best as possible. I had to make three templates for this insert, too - one for GB/GBC, and two for GBA - one for regular games, and one that holds two cartridges for those later Mega Man Battle Network games (which I plan on getting all of, so I'll probably redo MMBN3 to have both Blue and White on it. Also the game inbetween 4 and 5 is a fan translation cartridge of the otherwise Japan-only MMBN 4.5).
Shoutout to
Your Cool Uncle Marisa for the idea and the templates. A good chunk of the art I sourced from
The Cover Project.
