Pony Fantasy VI Remake

This is the part of damage modification that's affected by Morph, and though I haven't checked HatZen's documentation, this is definitely what his patch changes.

This is what it should look like if you want vanilla Morph damage modification (halve magical damage only), which you do if I understand correctly. If you DON'T want Morph to affect damage taken at all, change the BEQ to a BRA (that's "80" instead of "F0" at C2/0D1C. If you want it to affect physical damage too, replace the "80 0B" at C2/0D15 with "EA EA" (NOP x2).

Code:

C2/0D15: 80 0B        BRA $0D22      (Skip morph if physical attack)
C2/0D17: B9 F9 3E     LDA $3EF9,Y
C2/0D1A: 89 08        BIT #$08
C2/0D1C: F0 04        BEQ $0D22      (Branch if target not morphed)
C2/0D1E: 46 F1        LSR $F1
C2/0D20: 66 F0        ROR $F0        (Cut damage in half)
