Grand Cross Pinball
===================
Made from Raine source

----
Inputs get tested at $4aca2 on
TODO
----
Screen flipping support
Understand role of bit 5 of IN1
Eprom?
BGMs (controlled by OKI MSM6585 sound chip)
MSM6585: is an upgraded MSM5205 voice synth IC.
Improvements:
More precise internal DA converter
Built in low-pass filter
Expanded sampling frequency
Stephh's notes (based on the game M68000 code and some tests) :
- Reset the game while pressing START1 to enter the "test mode"
