N64 Cartridge Repair & Battery Replacement Service (USA)

N64 Cartridge Repair & Battery Replacement Service (USA)

Got an N64 game that needs some love? We've got you covered.

This service is for USA-based customers only. Simply add it to your cart and place your order — do not ship your cartridge until you receive our confirmation email with mailing address and packaging instructions.

How it works:

1. Place your order and wait for our confirmation email with shipping instructions.
2. Send your cartridge to us. Please ensure it is securely packaged.
3. We'll perform a full diagnostic and contact you with a repair quote before any work begins. Some minor repairs, including battery swaps, may be covered under the initial diagnostic at no additional charge.
4. Once approved, we'll complete the repair and invoice you for return shipping before sending it back.

Why won't my N64 game save?

While most N64 cartridges use flash memory for saves, some earlier titles do rely on a small internal battery. If your game is losing saves or won't save at all, a battery swap may be the fix. We'll identify the cause during diagnostics and let you know before any work begins.

Shipping

Shipping to us and return shipping are the responsibility of the customer. Return shipping will be calculated based on your location and invoiced separately prior to your cartridge being returned. Please refer to our shipping policy for full details.
