Continuing adventures of Cyberbox misbehaves with overlays and ATTRIB changes

[NebularNerd]

Describe the bug

The game Continuing adventures of Cyberbox from #3090 likes to play about with attribs during loading (why, who knows?) and will fail if you have it running inside a .zip or read-only folder with an overlay. From #3535 it was discovered it had this weird behaviour (look about two or three posts up to get the start of the conversation for this game), at first it looked like a bug in PHYFS so we left it at that. I've just tried to use it through a read-only folder and overlay and it produces the same results with the file errors.

This looks like however this game tries to handle the ATTRIBS it's doing it in a weird way and breaking something.

Steps to reproduce the behaviour

• Download cyberboxdlx.tar.gz from Display glitches in game "Continuing adventures of Cyberbox" #3090 and run from a folder.
• Pack to .zip or .7z, mount using mount c cyber.zip and mount c overlaydir -t overlay then try running again. You should see error as above.

Expected behavior

When using an overlay with a zip or read-only folder the expected behavior is that doing ATTRIB +h file.txt for example will create a new copy of the file in the overlay with the H (Hidden) attribute set. This game tries to adjust the ATTRIB's but fails due to some non standard method that prevents an overlay copy being generated.
