In Space Quest 1 VGA (not EGA) can you end the game with the cartridge?
This ending plays out as mine did, see 1:34:
"Now, if you'd only been smart enough to bring along the data cartridge containing the construction specifications, we'd be able (to) build a new Star Generator, thereby saving Xenon from the horrors of a rapidly cooling planet. Oh, well. You are just a janitor."
