2When you activate the jetpack you "teleport" high up and then fall way down. Lovely.
3Mwahaha, whenever you activate the jetpack you immediately die! Probably has something to do with clipping problems.
4When you activate the jetpack you go all the way down.
5When you activate the jetpack you go all the way up.
6When you jump, you jump to the highest point you can go, then you slowly fall back to earth. I have yet to test it with an activator, though.
7If you rapidly press C-Up and C-Down, you will instantly surface if you are underwater, or instantly jump up to the celing if you're out of the water.
8For ? is 0=off, 1=on. With this you can(works for everyone) walk through walls.
9With this you can have 0 computers or more than 4. Over 4 and you might end up being telefragged from so many computers coming in after death. You can sometimes end up force spawning in areas where you're not supposed to spawn in

11Most enemies do not move or shoot, but some do. This code freezes most sprites too (explosions, fire, etc.). Also, it only works in Singleplayer mode.
12This code works on all difficulties, but doesn't work on the clone battlelords.Another thing I learned is that each alien on a level has its own health address. Also found out how much damage certain guns do, for example the pistol does random damage from 4-10, explosive shotgun shells do 75 points, etc. But back to the Battlelord code cause I think it is interesting.

The first line of code in the memory editor starts at 09 then works its way down to 00 this represents how many times B.L. must have his life points worn down, think of it as his "remaining lives". I found this out cause when I used the second code line in the gs with 0000 I still had to shoot B.L. 10 times to kill him. The second line of code is how many hit points it takes to make him lose a digit from the first line. I believe he starts at 200. So I am pretty sure B.L. has 2,000 hitpoints. Heres where I was puzzled though and that is at the third line. I am not really sure what it does but I do know that if you enter the other two at 0000 and leave out the third code it still takes a whole crapload of hits to kill B.L.This number starts at 255 and goes down with each successive hit on B.L.,however it too cycles, restarting at 255(at least I assume it does, because it went from 255 to 6 to 14, and that was from me checking every couple of shots) I beleive this set of digits is also connected to B.L.'s hit points, but how I do not know. All I know is if the last four digits of the codes are reduced to Zero he dies in 1 hit. I am also not sure how i was able to make the first 2 codes work in the ten hits kills part without the third line entered. I will continue to test the code and try to learn more. I am also going to look for Overlords and Zeros health addresses. This could open up a new challenge; make Zero with infinite health and see how long you can last against him starting with the pistol and working your way through all of the weapons.
13Increases the speed of gameplay and is useful during multiplay on levels that suffer from slow down.
1463-Jet black. (but can be seen in normal colors by nv goggles)
10-shadowy and occassionally flickers. (like when duke is standing under a flickery light.)
20-pitch black flickery
03-default color
15(messing with these codes can be quite funny, as you can have
fat or skinny dukes.)

Size modifier digits
the first digit is for the top code and the second is for the bottom.

09/0C-tiny duke, just like if you were shrunk and can't use weapons.

17/10-Mini-Me, waist height duke, still can't use weapons.

2F/36-Hulk Duke, this guy is at least 7-8 feet tall ,
and normal dukes only come up to his chest.
he can use weapons. when he dies, his corpse floats above the ground.

2A/24-Dukes default size

the shrinker doesn't seem to work on size modded dukes.
size mods for player 2 work in multi and normal game modes.
