is there a direct way to detect VBLANK period on TMS VDP via hw?
i mean: it's possible to create a hw that allow via a in a,(someaddr) to get a byte that means: 'vblank' or 'not vblank' time?
i see only one solution: catching the int out from vdp then starting a countdown for vblk time to know if it's vblk or not.
Anyone could find a better solution?
thx
