I thought that only applied for the hidden-attribute, but copy&delete-protect-attribute does work on most if not all OSDSYS-Versions?! I thought before, that this isn't even defined by the file-attribute, but via a 'flag' inside icon.sys or similar. There are Save-Games which can not be copied - for sure - via the OSDSYS... I guess they still can be deleted. It doesn't only apply to multi-installs... Every kind of installation could be 'child-proof' (atleast when deleting saves via the OSDSYS) with this... and who would like to copy FMCB to another MC just to experience a BSOD on the other MC, just because it hasn't been installed?! Alright, so another more complete method would be preferable...?!
