Liability Notice:

This is an add-on device not originally designed for your vintage video game system.  As such, it is always possible, however unlikely, that some harm might come to your vintage gaming system by using this device.  Given the nature of failing capacitors and aging electronics, I cannot predict all behavior and results.  Every board is thoroughly tested prior to shipment and all boards include fuse protection.  However, please use this product at your own risk.

While everything for sale on this page is thoroughly tested under many conditions, due to the homebrew nature of the boards here for sale and the vintage equipment they are designed to work with, I cannot be held responsible for any damage done to your consoles or belongings.  Many vintage game systems suffer from leaking capacitors and other ailments due to age that are outside of my control.  Install all products at your own risk.
