Instead of fixing what’s broken, I am doing whole install again. I already have roms in USB that is in Ext4 format. I will disable USB rom service and run through smartroad’s method. I will also replace es_systems.cfg with changes such that roms are pointed to USB drive.
I don’t think roms are bad and I have been using the bios that should work (never can verify that) but I have unzipped them while keeping the zips intact in the same folder.
