Making a Weapon Deal 2x Damage to a New Monster Type

For the record there was a problem with the heal rod effect being once-per-strike instead of once per target.You need to switch the two entries in the pointer table, so $C23DE5 = 7E3F and $C242F9 = 8C38. In his case, Gi Nattak had room at $C21692 so he changed $C23DE5 to 9216.

Finally hooking up the following code did the job:

Code:

org $C21692
LDA $3C95,Y
BIT #$20
BEQ .branch
INC $BC
INC $BC

RTS
