Wow no room in the rom? No speech, no multiball, what takes up all the space? Sound data?

Ah, yes I can see a lot of code being used for lamps. There’s a lot going on with light shows and such.

Is there room to add one more lamp in the matrix? I always wanted to mod mine with star post lights on each side of the K target so they can blink for extra ball like the lane guides.

I always thought PIGS should have a two byte relative branch instead of needing to use a three byte jump just to skip over a couple of instructions or repeat a loop. That would be a great macro to add.

You are correct the K lamp flashes when lit for extra ball.
