From The Black

crystals  are 4 byte.

Dunno whether it's by design or fluke but whenever I try to scan for a variable (I haven't even changed it yet) the game automatically hangs on pause screen

I'll just leave this here:

[kind of] invincible (2 values)
11 08 00 00 29 d0 66 9f 06 24 00 af
11 08 00 00 29 d0 66 9f 06 24 7f ae

(this is based on the shield timer, instead of checking for a value [of the shield timer] greater than zero to return from the collision functions unharmed, now it checks for a value smaller than a large number, it may be possible to get damaged if you collect too many shields)
