Describe what's going wrong

Right now D1MODE_V_COUNTER is set to be 720 (0x2D0), however certain titles checks it while trying to playback videos, which causes them to stuck in infinite loop.

After spending a bit of time it seems like value must be changed with frequency at least 120 times higher than actual vsync (probably 720 to match amount of lines being draw) thread, however I haven't checked exact frequencies yet.

After some time with it I expect to be updated every 1/(display_refresh*horizontal_lines)

Screenshots just for future:
