 - emulate LCD at lower level, probably an MCU with embedded LCDC
-- LCD status bit handling is guessed. stratos expects it to be high after lcd command 0xf,
-  but tking2 won't work if it's done that way, and corona is different too
-- irq timing is derived from the main XTAL, but result should be similar with 5MHz and 5.67MHz,
-  there are a couple of "FREQ. SEL" nodes on the PCB, maybe related (not the ones in input ports).
-  irq source should be from HELIOS pin 2
-- tking(old revisions) and stratos slow responsive buttons, related to irq timing, but if that's changed,
-  the led blinking and in-game clock is too fast
