==== GA: Moustache testbench ====
A homemade Testbench done firstly for helping Sorgelig to calibrate it's port of FPGAmstrad into MiSTer. But as Sorgelig core does run finer than mine (Pinball Dreams did pass !WAIT_n:slow, CRTC 1, Brand name: Amstrad), I do then take back the good behavior using this testbench, resulting r005.8.16.1
It's a stress testbench around VSYNC/HSYNC/interrupt.
