Hi All,
The same problem as above for me. I am using Retropie V3.0 Beta 4 with a 32 GB micro sd. Did a binary update and script update. Same errors as DragonJarvis. Mame Emulators work fine. Also Ports work fine. All other emulators do not work. Roms are in the list but when I select one it brings me back to the list. Also rom names appear to be grayed, not in boldface like they previously were. Any help on this would be massively appreciated. Thanks in advance.
