Well, yes you can disable autosaving.

In Pak0.pk3 under the folder 'Global' there
is an 'Autosave.scr' file that you can edit.

I just rem'd out all the lines between 'set'
and 'end' and it seems to work. I didn't
delete them in case I want it back.

I use a program called 'PakScape'. I found
it on a Quake 3 website. (do a search)

I do not suggest modifying the original pk3
files. Make a new one with the Mod.
