I forgot to tell you to delete the garou files from the sd card bup folder. The full steps are:
Delete all files starting with 'garou' feom the sd card BUP folder.
Place your sd card back into neosd nut don't plug the mvs board yet.
Set all dips in the mvs to on.
Turn it on, when work ram test shows, turn it off.
Restore your dips settings.
When trying with arcade mode on, also ensure the sd card is not inserted in neosd.
