Super Mario RPG unknown cart mod

I got this mario RPG cart recently... It doesn't work, but does anyone know what this mod is supposed to do ?? The chip is upside down so I can't see what it says.

 

It seems to be some sort of CIC Hack attempt.

 

agreed. the rom wasnt touched.

 

Very interesting, first time I have seen something like this.

 

Looks to me like it's trying to overcharge and therefore disable the cic inside the SNES in order to circumvent the region lock.
It takes VCC from pin 58, charges the two huge caps with it and feeds it through the little IC and then applies it to pin 56 which is the cic clock.

Just remove it.

 

Yeah besides that if you want Mario RPG in PAL you just need to lift a pin of the SA1 Chip if i remember right.

 

All you need to do is either lift pin 127 and connect it to 5v VCC or you can cut the trace going to pin 127 and connect a wire to VCC.
