thought I’d share his device, he is out of stock but has made 5 of them. I was able to test one myself but it didn’t work with Waterworld, Jack Bros, insecticide or Hyper Fighting.
I don’t know if other home brews will have same issues.
Should message and follow him though, I don’t think he is a member but let him know we are interested in making more
You’ll need to update the Retrode firmware to the latest version to read some games. Hyper Fighting and Red Alarm are two well known problem carts. I think the latest firmware is 0.26b or something. It’s been awhile since I dragged my Retrode out, so I may be wrong there.
