All code that can be run with PI on Japanese

All code that can be run by touching powerups with various PI's on Japanese.
(For what powerups trigger what code, see here: https://dl.dropboxusercontent.com/u/183608682/PI2.xlsx )


C56D:
make mario big

C5F8:
give mario fire

C59E:
make mario invincible

C5A4:
give mario cape

C60A:
give mario 1-up

C57B:
give points, play sound

8D0D:
no significant effect

A50D:
crash the game

A971:
crash the game if sprite touched is not feather
respawn the feather just touched
mess with bounce sprites a little
change the screen exit of screen 1E ($19d6) to zero
mess with extended sprites a little
set sprite #7 to not interact with objects ($15e3)
skip processing any sprites with a lower sprite number this frame

DA6E:
teleport mario to the right

EAFA:
set X speed of sprite in slot 7 to double+1. Note that many sprites reset their speed every frame or ignore this value entirely.
???maybe more effect under some circumstances???

9D85:
crash the game

C615:
crash the game

A9C5:
set eaten sprite to stunned, or dying if killed when jumped on

B422:
no significant effect

B820:
no significant effect

EC24:
no significant effect

8A03:
crash the game

9EB5:
crash the game

F98D:
no significant effect

A014:
no significant effect

B903:
no significant effect

80A9:
crash the game

BC04:
crash the game

D8A9:
no significant effect (very powerful on USA, though)

EA2D:
reset some bits of sprite 3 Y speed
copy touched sprite's Xpos high byte to sprite 3's disable contact timer
copy touched sprite's Ypos high byte to sprite 3's stun timer (must be set to 2 or higher to spawn anything)
attempt to spawn a sprite in slot #6f, with the following effects -
corrupt sprite #1's graphics a bit (set YXPPCCCT to all zeros)
set sprite #3's third tweaker byte to 0 (allow killing with cape/fire)
set sprite #3 to interact with objects if disabled
set sprite #1 to not in water
mess up bounce sprites a bit
set high byte of minor extended sprite #0 to zero
set sprite #3's fourth tweaker byte to 0 (use default interaction, don't give powerup, change into shell when stunned, non-permanent, killable by star)
if sprite 3 is goal tape, make it keep going higher (but don't move the bottom of the tape activation region)
set 160f (misc sprite table for sprite #1) to 01
the game considers the sprite in slot #6f to have its sprite number stored in 10d, therefore -
set sprite #3's second tweaker byte (sprite clipping) to a value in the range 0-F depending on uninitialized ram
set 197e to a value determined by uninitialized ram, which may change whether the 70th (0x46th) sprite in the level can (re)spawn
if touched rather than tongued, set X register (sprite currently being processed) to 08. this allows for some sprites to have their code run multiple or zero times in a single frame, and it also makes some code intended for powerups get run on sprite #8 (typically moving it to the right a bit). ?maybe other stuff possible?

E8A9:
crash the game

95C6:
whichever block was last hit by below by a sprite (or in some cases Mario) ($1868), act like such a block was hit again. confusingly, it will spawn in layer 2, but based on Mario's position in layer 1. (if outside layer 2's valid range, it may actually appear in layer 1 at a far away position. however corrupting non-map16 data does not appear to be possible.)

BD03:
no significant effect

A914:
hurt mario

908D:
no significant effect

C678:
no significant effect

B553:
crash the game

DA0E:
if holding up (and not carrying item or on yoshi) when touching powerup, enable climbing on air and warp mario right by the value in 18B6 (which is typically 20)

A508:
crash the game

C90D:
no significant effect

AE03:
crash the game

A503:
crash the game

9901:
no significant effect

A91D:
no significant effect

C6F4:
crash the game

AD0A:
