I have a hot tip to easily ahave all roms in one folder while having them alphabetical still with sorting disabled. If you use the windows cmd prompt copy command to copy all the roms, it will copy all the roms in order alphabetically. So if your roms are in c:\roms and your everdrive is e:\roms you would run CMD and type this command
"copy c:\roms\*.* e:\roms\" without the quotes and this will copy them all in alphabetical order and they will show up alphabetically even with rom sorting disabled, allowing all roms to be in one folder and still sorted.
