Includes support for vectorized interrupts, non maskable interrupt and CRTC cursor signal support.

[[MAME]] emulates the 2xYMZs and the CTC lets you set YMZs clock, NMIs and Cursor Interrupts. In this moment only lacks of the support of daisy chain setup to acknowledge IRQs for using the normal timer/counter interrupts.
