Notes
1Warning: Don't get anything that gives you life.
2Note: The `Ice Beam' will look unusual, but works normally. You do not start with any Energy Tanks or Missiles. A password will save the items, but not the invincibility.
3After you die, press A direction and you come back to life with no energy.
4Samus may de-atomize when hit
5Note: Most codes ending in TIK will cause changes in horizontal movement.
6Samus doesn't though, but appears next time the screen scrolls.
7Note: Ice Beam will look unusual, but works normally. You do not start with any Energy Tanks or Missiles. A password will save the items, but not the invincibility.
8After you die, press a direction and you come back to life with no energy.
9It takes you to the same place.
10That is, the power-up that changes you into a ball is "stuck to the wall".
11Only works when you Don't have high jump boots.

NOTE: Credit goes to Parasyte for his excellent 6502 asm tutorial which helped me make these jump codes.
12Only works when you Don't have high jump boots.
13Only works when you Do have high jump boots.
