Desperation Attacks

So one aspect of Final Fantasy VI that is just about tossed aside is their Desperation Attack system. It's essentially the basis for the Limit Breaks seen in newer games, where a character at low HP has a chance to perform a powerful attack as a last resort, i.e. when they're at their Limit. But the problem with it in VI is that the chance of it coming is so low, it's generally just another form of a critical attack seen very rarely. So I was wondering, would there be any way to change the odds/chance of performing a Desperation Attack so that they happen more frequently? My hack is centered on a heavy storyline with great emphasis on each hero's character, and as such, having each character have their own Limit Break and having it actually happen often enough would add somewhat of a more unique feel to each character.

Take a look in the C2 bank document on assassin's site, and search for 'desperation attacks'.
Here's a small part of it that you would want to change with a hex editor.

Code:

C2/15EE: D0 20        BNE $1610   (1 in 16 chance for DA)
C2/15F0: B9 18 30     LDA $3018,Y
C2/15F3: 0C 2F 3F     TSB $3F2F
C2/15F6: D0 18        BNE $1610   (No DA if this character already used it this combat)
C2/15F8: B9 D8 3E     LDA $3ED8,Y (Which character it is)

I created a simple patch a while back that allows the DA to happen anytime regardless of health, but that's it. It's in the patches section. To allow the DA to happen more frequently, the above code needs to be changed just a bit.

So I was wondering, would there be any way to change the odds/chance of performing a Desperation Attack so that they happen more frequently?

Original code:

Code:

C2/15E9: 20 5A 4B     JSR $4B5A   (Random number 0 to 255)
C2/15EC: 29 0F        AND #$0F    (0 to 15)
C2/15EE: D0 20        BNE $1610   (1 in 16 chance for DA)

Beside Gi Nattak solution, for simply increasing the odds, you could do a AND #$1F instead of the AND #$0F that is there . This would double your chances (12.5% instead of 6.25%).
