[quake2] Savagame

[Brendan Burns]

A platform neutral saved game format would be cool...  As tei points 
out, it needs to serialize *everything* in the game state.  Id is 
already doing this, but they're doing it via memory dump rather than 
true serialization.  Not hard to change, but a fair amount of work.  
Again, I'm not going to do this in the near future, but I'd be happy to 
help guide someone through the process...
