Support information

I'm a huge N64 enthusiast, and this is a side project I've done out of my love for the platform. Because of real life I probably can't answer emails immediately but I try to check up every 2-3 days.
Please email only the below address for correspondence about 64drive.

About outstanding orders (2021):
Orders are still turned off due to the backlog. I have plastics starting production now (yes, finally). Apologies for the many people who have had orders delayed for a very long time. I am shipping orders as I can for now, once plastics are done orders will be quickly caught up. - Marshall
