Load the first file after Jumpman* by typing
LOAD"FILE*",8,1 (substitute the actual name for FILE)
and pressing return (after you have Ccs64 running, and 
the proper disk selected!). For unlimited lives, then
type: Poke54296,15:Poke24015,173:sys36864 (all on one line)
and press return. The game will run & you'll have 
unlimited lives!
