===Effect of the side effect-fixing code===
When using the Mail Writer, the assembly from this code is directly written and executed as follows:
<pre>
21 7A D6 ld hl, $D67A ; Address where the original pokégear flags have been displaced to
2A ldi a, (hl)
23 inc hl
F6 84 or $84 ; Ensures that minimal pokégears are restored if $D67A is empty
22 ldi (hl), a
AF xor a ; a = $00
21 E1 D5 ld wNumKeyItems ; Current amount of key items in key item pocket
47 ld b, a ; b = $00
4E ld c, (hl) ; Set c to amount of key items
09 add hl, bc
23 inc hl
36 FF ld (hl), $FF ; Restore cancel button to key item pocket
2E FC ld l, $FC ; hl targets wNumBalls
