@ -11,13 +11,12 @@ TODO:
- dkong3 dma (Z80 dma)
- implement 74LS259 (8bit addressable latches),
74LS175 (QUAD D FlipFlop), 74LS373 (Octal transparent latch)
- for documentation: hook up speech interface still present on radarscp (TRS02)
and early dkong (TKG02/TKG03) pcbs.
Minor priority since no records known where this has been used.
Done:
- when i am retired: implement 8257 DMA controller
- drakton - add dkongjr conversion
- for documentation: hook up speech interface still present on radarscp (TRS02)
and early dkong (TKG02/TKG03) pcbs.
- radarscp_grid_color_w() is wrong, it probably isn't supposed to change
the grid color. There are reports of the grid being constantly blue in
the real game, the flyer confirms this.
