/* /*
Wild One and Golden Poker need to check the value in the CURSOR register of the crtc prior to starting but
CURSOR appears to be unconnected on the Mark IV schematic so its unclear how this update is implimented.
I suspect it to be connected to the CPU IRQ and the value in crtc: 0xf read every VBLANK until it reaches 0xff
Wild One below. Golden Poker has the same routine.
'maincpu' (9137):M6845 reg 0x0f = 0x00
907D BITA $1800 ; crtc reg 0xf
9080 BNE $907D ; branches 907d if value is not zero.
9082 BITA $1800
9085 BEQ $9082 ; branches to 9082 until value is 0xff
9087 LDA #$40
Using mc6845_update and cursor update callback causes the "Invalid MC6845 screen parameters - display disabled"
so a work around is required.
