VDP Commands

[artrag]

This rom on WEBMSX shows black one line out of 16 while the screen is scrolling at max speed (1 pixel per frame)

https://webmsx.org/?ROM=https://github.com/Maneldemo/Uridium-2-for-msx/raw/refs/heads/master/shooter_scr8_asm/urd_scr8.rom

But the same rom on real HW and on openmsx works perfectly

The problem could be related to timings of the vdp commands
