Notes

Poker Ladies bootleg made by Playmark (PM stickers and pcb layout is same as many others Playmark bootlegs)
PCB is jamma standard while the original is mahjong pinout and require matrix inputs.
It has no EEPROM but 2 banks of dipswitch
The bootleg has some gfx glitches (flickering of the text) and the colour of the background is totally black.
Encrypted custom z80 in epoxy block. Clock is 12mhz/2
YM2413 clock is 3.75mhz. The 7.5mhz clock, which is divided by 2 by a 74ls74 before going to the YM2413, is too difficult to follow.
It is derived from the 10mhz pixel clock since shorting it the video goes out of sync and the music change in pitch/speed.
Oki5205 clock is 384khz (resonator)
Vsync is 59.09hz
