Recovering an online savegame from a partners save

[6667a052d301bVegoraptor]

Hello there,
as some of you might know, I am a bad person making another Let's Play of System Shock 2, as if there werent enough, I know.
However, I got hit by a rootkit a couple of days ago and had to format my drive, losing all my saves. My partner was so kind to back me up his ones, but we both have no idea how to correctly tinker with the data, as we both spawn at the same position in different "realities", not able to see or interact with eachother, alongside with personal bags at my old position.

My question is, would there be any way to replace his coordinates (Snowfire247) with mine (Vegoraptor) and if so, might anyone be so kind to help me out?

Thanks in advance.

EDIT: Why is this in Engineering, I posted it to the helpdesk...

I know that Nameless Voice told me he had tried that. Long time ago. I don't remember there being any special precautions to make copies of characters work. Paging NV to this thread. Maybe he can tell.

Somewhat solved, got the zombe level selector to work.

Don't go to lower levels, their mission subjects will be unsolved.
