Thanks for the info. If the fact that something is a VDM is available when the menu is being generated this would be an easy fix. If not probably not worth doing. I don't know if it is available but I will check.

This would require you making a case for this being needed by ArcaOS for something (retro gaming?) and I would then expect lSwitcher to at minimum be an install option for ArcaOS.
