Steal, GP Rain, and Steal GP as Spells?

In the Fanatic Tower, command $02 (Magic) is replaced by nothing ($FF). Coomand $1D is replaced by $02. Here is the code. It is based on command ID, regardless of what the commands do:

Code:

C2/5382: AD BB 3E     LDA $3EBB     (Fanatics' Tower?  must verify this.)
C2/5385: 4A           LSR
C2/5386: 90 12        BCC $539A     (branch if not in the tower)
C2/5388: B5 FC        LDA $FC,X     (get menu slot again)
C2/538A: C9 02        CMP #$02
C2/538C: F0 08        BEQ $5396     (branch if Magic command, emptying slot.)
C2/538E: C9 1D        CMP #$1D      (MagiTek?  actually, this is former Fight or Gau+Rage.)
C2/5390: D0 06        BNE $5398     (branch if not)
C2/5392: A9 02        LDA #$02      
C2/5394: 80 02        BRA $5398     (save Magic as command)
C2/5396: A9 FF        LDA #$FF      (empty command)
C2/5398: 95 FC        STA $FC,X     (update menu slot)
C2/539A: CA           DEX
C2/539B: 10 BD        BPL $535A     (loop for all 4 slots)

Steal GP is only the Steal command branch (C2/3A09) when a monster is using Steal. It cannot work the opposite way unless you code a new command or code yourself GP stealing when a character steal.
