Custom Game Cases for your Super Nintendo Cartridges!

If you’re like me, you’ve got a stack of loose Super Nintendo cartridges lying around - awesome on their own, but they tend to look messy, collect dust, and don’t always stack neatly with other systems. That’s where universal game casescome in, and they’ve made a massive difference in how my SNES games are stored, displayed, and preserved.
What Are Universal Game Cases?
These are empty plastic cases designed to house retro game cartridges - SNES, Genesis/Mega Drive, etc. - and protect them. The version I use is the “Universal Case” from Amazon Australia (for the Genesis / Mega-Drive / Nintendo / etc.) which is the same idea: clear (or translucent) plastic with a sleeve around the outside so you can slip in cover artwork. They make the whole collection look uniform, clean, and more like a display than just a box of cartridges.
Why I Love Them
Protection: Dust, dirt, moisture, exposure are big enemies of old plastic and the metal contacts of cartridges. Putting them in cases makes a difference.
Organization & Shelf Appeal: Uniform cases mean no weird-shaped cardboard boxes, no leaning cartridges. Everything lines up like a neat row of books or DVDs.
Custom Artwork: The sleeve means I can slap in a nice front cover so you know at a glance what game it is, even from the spine. Makes the shelf feel more like a curated collection.
Cost vs Benefit: Even though they cost something, the value per game stored ends up being low, especially once you do a bunch.
How I Get the Artwork — Cheap & Simple
This is where the fun DIY part comes in. I don’t buy the artwork pre-printed. Here’s my method:
Find high-quality scans: I use TheCoverProject.net. It’s a community site with scans for a huge number of retro games. You can usually find front covers, back covers, spine images etc.
Supplement with Google if needed: Sometimes the exact version I have isn’t in TheCoverProject, so I’ll do a Google image search for “SNES game name cover art scan” or similar, maybe filtering for larger sizes.
Arrange and edit: Sometimes I resize or tweak the image so it fits nicely in the case sleeve. I make sure the proportions match the sleeve dimensions so things don’t look stretched.
Print: I print my covers at home (or sometimes a local print shop) on nicer paper if I can. Usually regular print-paper is ok, but a slightly heavier paper works better so it holds up.
Trim & Insert: Cut to size, insert into the plastic sleeve of the case. The sleeve keeps it flat and protected.
DO NOT SELL THESE CASES WITH ARTWORK!
Because I do all this myself, the artwork costs maybe 50 cents per game (if you already have ink/paper). Roughly $10 Aud for the case. For that small extra effort, the upgrade in look, protection, nostalgia — it’s totally worth it.
Some Things to Watch Out For / Tips
Measure the sleeve radius or size first, so your artwork doesn’t leave margins that obscure the image or look sloppy.
Use a paper type that doesn’t warp much with humidity. If your area is humid (like parts of Australia can get), avoid super thin paper or get a heavier weight.
Keep ink from smudging — let prints dry, maybe even use a light spray fixative.
Be careful with the plastic sleeves — sharp tools when trimming, gentle handling so you don’t scratch the plastic.
Over time, UV light can fade colors; consider keeping the shelf out of direct sunlight.
Final Thoughts
These universal cases are a small investment for a big impact. They let me keep the history visible — the art, the plastic, the vibe — while keeping everything neat, protected, and display-worthy. Plus, there’s something satisfying about building out a shelf of uniform cases all with matching assests under clear plastic.
