Description

This hack remove the last elemental weakness set by the debilitator on a monster before setting the current elemental weakness picked in the debilitator special effect code, meaning a monster can only have one current elemental weakness set by the debilitator.

To achive this, the RAM hack use 6 bytes of free RAM to store the last elemental weakness set by the debilitator; $3E2D, $3E2F, $3E31, $3E33, $3E35 and $3E37, also known as $3E25,Y (or $3E25,X) in the code for a character/monster. The "no RAM" hack use more ROM space and reload the elemental weaknesses from the monster data before applying the new weakness set by the debilitator.

The bank $C2 RAM hack use 23 bytes of free space at $C26469 and the EX hack use the same amount at $EEAF01. The "no RAM" hack use 59 bytes of free space at the same offsets. Those free space offsets can be changed in a ASM file by changing the offset of the "seek" macro call. All hacks insert a JSL or JSR in the debilitator special effect code at $C23AA8.

To assemble the hack use bass v14 by typing a command such as "bass -o rom.smc debilitator_C2.asm".
