MiSTer FPGA Forum

I've been able to use the previous Genesis/MD core without issue the past couple of years with roms stored on a USD hard drive. Then I see there's a "new" core. For some reason I can't get to my root and point to the USB hard drive where my games are though the MiSTer UI. I've never had an issue with any other core doing this process. Whenever I keep pressing on the dots to back up one level in the directory tree I don't ever get to the root tree if that makes sense.

it's looking in the MegaDrive folder for games.

You can either move/copy your files to the MD folder or create a symbolic link in the MD folder
