[Thunderbirds (JP) - DMG] fails to start, white screen

[ITotalJustice]

@Calindro explained the cause of this issue.

basically, stat interrupts share a single line. Meaning that if both mode 0 and 2 interrupts are enabled (allowed to fire when entering mode), and we are in mode 0 so the stat line is high, going into mode 2 will then keep that line high, meaning another stat interrupt will not fire.

I currently just fire interrupts on mode switch 😄

I'll fix this (hopefully) later today
