SNES cartridges can go bad over time due to factors such as oxidation and corrosion of metal connectors, battery failure, PCB damage, and decay of EPROM and flash memory. These issues can lead to glitches, freezing, data loss, or the inability to load games. In this article, we explore the various ways in which SNES cartridges deteriorate and provide insights on how to preserve their functionality for long-term enjoyment.
Oxidation and Corrosion

One common issue affecting SNES cartridges is oxidation and corrosion. The metal connectors present on the bottom of the cartridge can oxidize when exposed to moisture or humidity. This oxidation creates a layer of corrosion that hinders proper electrical contact with the console. Corrosion can lead to poor or intermittent connections, resulting in glitches, freezes, or the inability to load games.
Battery Failure
Certain SNES cartridges, particularly those that include save functions, rely on a built-in battery to retain saved game data. Over time, these batteries can deteriorate and eventually fail, causing the loss of saved progress or the inability to save new data. Battery failure can also lead to other issues, such as difficulty booting the game or instability during gameplay.
PCB (Printed Circuit Board) Damage
The printed circuit board within SNES cartridges can be susceptible to damage over time. Excessive heat, moisture, physical stress, or improper handling can cause the PCB to develop cracks, damaged traces, or faulty solder joints. These issues can disrupt the flow of data between the cartridge and the console, resulting in game instability or complete failure to load.
EPROM and Flash Memory Decay
EPROM (Erasable Programmable Read-Only Memory) and flash memory chips used in SNES cartridges have a limited lifespan. Over time, these memory chips can decay, leading to data corruption or loss. This deterioration can manifest as graphical glitches, audio issues, or even the inability to boot the game entirely.
How to Preserve SNES Cartridges
While SNES cartridges can deteriorate over time, proper care and preventive measures can help prolong their lifespan and maintain their functionality:
- Storage: Store SNES cartridges in a cool, dry place away from direct sunlight and excessive humidity. Using protective cases or storage solutions specifically designed for retro game cartridges can help prevent damage.
- Cleaning: Periodically clean the metal connectors on the bottom of the cartridge using isopropyl alcohol and a soft cloth or cotton swab. This helps remove oxidation and ensures proper electrical contact.
- Battery Replacement: For cartridges with built-in batteries, consider replacing them before they fail. This can help preserve saved game data and prevent potential issues caused by battery decay.
- Gentle Handling: Handle SNES cartridges with care, avoiding excessive force or bending. Proper insertion and removal from the console can help prevent damage to the PCB and connectors.
Conclusion
SNES cartridges are prone to deterioration over time, primarily due to factors such as oxidation and corrosion, battery failure, PCB damage, and memory decay. Understanding these issues and implementing preventive measures can help preserve the functionality of these beloved cartridges. With proper care, collectors and gamers can continue to enjoy the nostalgic experiences provided by the SNES for years to come.
