I had to redo my arcade because my last pc went out on me. I know I have the bios setup correctly with the right md5sum off the reicast core info site. I was using Dreamcast reicast just fine on my last pc build with a few games not loading with redream. Now when I go to launch reicast it immediately just flashes a black screen then goes back to the Retroarch menu. When I choose redream it says it cannot load the core. I don’t know if something went wrong with this installation but I did have to copy over the auto config .txt files for all the controllers from my brothers pc that has retroarch working fine. So I tried to do a redownload and update without any game booting still. Any suggestions? Thanks!
edit, it should be noted everything else works fine with this fresh build including using psx and having this bios files loaded just fine.
