[Coco] Help with Nitros9 on SDC?

[L. Curtis Boyle]

So am I. Especially with plugging it in straight to the cartridge port. Unless something is blown on the cartridge port that it’s not reacting properly. I take it that you have tried redownloading the EOU image, just in case something got corrupted? You can also try going back a version or two and see if that makes a difference; 6.0.0 & up had the auto-detection added. Maybe 5.* is worth a try.
