There's two saved game files both with 254 lives. One is part way through
level 5, the other is at the begining of level 6.
Just rename the "file." with your own pilot name & the ".sg(*)" with the 
save-game slot(#) of the slot where you want the save placed.
Remember, The Save-game slots are numbered .sg0 - .sg* . Just make sure you 
pick a slot that is not allready being used. Then dump the file into your 
Games\descent2 directory (of course!), Then go have a BLAST!
254 lives should be enough to keep you in the action for a while!!!
