I've had the MegaSD for some time and all has been good. I picked it up again yesterday and found that Sega CDs won't load. They revert back to the CD console once selected. I've tried moving one into the root directory with the same result. All my settings in the MegaSD are correct, the BIOS is working fine and my MegaSG settings are good too. I tested on my Nomad to be sure it was the MegaSD with the issue and got the same result.
If anyone has suggestions, I'd really appreciate it. Todd - I'm not sure how to log a formal issue, but let me know if I'm not missing something and still have the issue after any troubleshooting.
