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 (2019-May-19):
I've barely had any time to send out orders. Because it's pretty time consuming to mod each donor case for fitment I am moving to injection molding <pic>
New orders are on hold so I can catch up on existing ones (there are a lot!)

Again, I apologize again for the delay as well as the site flakiness. My host migrated to a new platform and I lost much of the emails on the old support account. When I get a few spare hours scraped together I will move everything onto Dreamhost.
As I ship older orders I will email to confirm your shipping address is still current.

If you have questions on your order, can't wait for a refund or need to change the shipping address, I've set up a temporary address -
Thanks for all your support and I will get all these orders sorted soon as possible. - Marshall
