Retro-game preservation is an important aspect, especially if you have rarities. Here are a few tips that can help you keep your games in good condition: Store games in protective cases or cases. This will help protect cartridges and discs from dust, scratches, and damage. Avoid extreme temperatures and humidity. The ideal place to store retro games is in a dry and cool place where they are not exposed to direct sunlight. Clean game cartridges and discs before use. Use a soft, dry cloth or special cleaning products to remove dust or dirt that may damage the game media or cause reading problems. Be careful when inserting or removing games from the game systems. Avoid sudden movements or improper positioning to avoid damaging the contacts or the game case. I learned about this from this Retro Game Store.
