Oh Ok I understand now!! Awesome. I was looked at the IM 2 program and to my
amazement I understood what was going on. If the I register was $FA it will
jump to $FA00 plus the number it got from the bus, up to 256. Then it takes
a 16-bit address from this 16-bit address table and jumps there, which in
that program is $F8F8

Asm is really quite simple... Damn I'm good ;)
