I thought that only applied for the hidden-attribute, but copy&delete-protect-attribute does work on most if not all OSDSYS-Versions?!Although it exists, it's not supported by the default browser.
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...The only people who really need to use the multi-install, are those who must save every KB of space on a memory card and somehow have PS2s from multiple regions. So unless you have such a use-case, try to use a normal, single-region installation.
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...?!It is a feature of FMCB, since v1.90. It just doesn't cover everything as completely as we thought.
