TODO:
-- add LCD (188:88, 88:88, and 7*7 DMD bottom-left)
+- emulate LCD at lower level, probably an MCU with embedded LCDC
+- add LCD 7*7 DMD, it's in m_lcd_data[0x30 to 0x3b] but scrambled
- corona: different addressmap, 64 leds
-- add endgame rom (softwarelist?)
+- tking different internal artwork
+- interrupt 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)
+- does nvram.u7 work? it's cleared during boot, but not used after
- clean up driver
-- does nvram.u7 work?
