I woke up this morning thinking about those cheats
Tried to remember what I did. I believe this is what I did:
C/program files/lucas arts/indiana jones and the emperors tomb/game data/default.cfg
Open "default.cfg" with notepad and add the line "cheat:1" just below "nocontrol:1". It should look like this (be sure to backup your file first "just in case"):
I don't remember where I found the cheats; just did a search on Alta Vista.com. Indy will not take any damage but if he falls from too great a distance, he will die. You need to quit and restart if that happens because he will just lie there forever, haha.
