Quarter of a million wishlists show I am not alone in wanting to restore my old game cartridges

There is something weirdly powerful about the idea of taking an old, battered video game cartridge and making it look loved again. I actually do this for real with carts and cassettes I pick up for my stupidly large retro collection. If you have never tried to restore a game box with a Sharpie, well, you haven’t lived.

Parasol Corp is clearly hoping plenty of people feel the same way as me, as Cozy Game Restoration now has a release date and will launch on Steam on September 24, 2026.

The Australia-based developer revealed the date during Frosty Games Fest, alongside a new release date trailer showing off the game’s gently nostalgic restoration loop. Better still, the first public demo is now live, and will also be part of the June Steam Next Fest, giving players a proper hands-on look ahead of launch.

Cozy Game Restoration has already passed 225,000 wishlists on Steam, which is a massive number for a quiet little game about cleaning plastic rectangles. Then again, it is also not hard to see the appeal. This is the kind of premise that gets into your brain immediately if you have ever owned a drawer full of old carts, battered cases, sticky labels, or mystery games from second-hand shops.

The setup is simple. Players receive mystery parcels containing forgotten retro game cartridges, then set about restoring them. That means peeling away tape, removing stickers, cleaning dust and grime, clearing ink and adhesive residue, and generally turning something that looks ready for the bin back into a collectable worth putting on a shelf.

There are no timers and no fail states. Cozy Game Restoration is very much aiming at the satisfying, tactile end of the sim market, where the reward is not a high score but the quiet little brain tickle of making something messy look nice again. It sits somewhere between restoration video, cozy collection game, and retro gaming nostalgia trap, and I mean that in the nicest possible way.

‘Cos you’re filthy

The cartridges themselves are procedurally dirtied, so each one should arrive with different conditions, imperfections, and visual problems. Some might have cracked shells, others might have clean labels, scuffed plastic, pen marks, discoloration, or stubborn residue that needs a bit more attention. The idea is that every restoration feels slightly different rather than simply repeating the same wipe-and-polish routine.

Across the full game, players will be working to complete a collection of 108 distinct titles inspired by games from the 1980s to the early 2000s. There will also be rare regional variants, unique artwork, different shell types, collection-based quests, and decorations and cosmetics for the player’s collection room.

Parasol Corp is also using Cozy Game Restoration to nod toward the wider indie scene, with collectible cartridges inspired by real games from Australia, New Zealand, and beyond. Deep Field Games has already given permission for Abiotic Factor to appear as a collectible cartridge, with more collaborations to be announced closer to release.

“Cozy Game Restoration is a love letter to the games that were with us growing up and the moments we experienced around them with friends and family,” said Parasol Corp founder Adam Stormhardt. “It’s wonderful to know so many people resonate with restoring and collecting battered old retro games, and I’m excited to finally be able to point to a date on the calendar when it’ll be ready. Being able to feature games from fellow Australian and New Zealand developers as collectible cartridges makes the project even more special.”

Cozy Game Restoration launches on Steam on September 24, 2026. The demo is available now and will be featured during Steam Next Fest, which runs from June 15-22.
