I've got a pal WORMS cart here, matched the pcb against an american game pcb and the pinout / form factor of the pcb is the same cross region, however there's a different lock out chip. I'm taking a shot in the dark that the GG has a lockout made for your PAL snes and will cover up the fact you're using NTSC games and allow for the difference in cartridge shape as it sticks up out of the system removing the size / shape factor from the equation. I could be completely wrong but I've heard of people getting around the physical lock out this way in the past.
