Missing black row on the game "Pinball Tycoon (Europe)"

[wwark]

Hi,

You will find the screenshot of mgba:

From a NDS

The missing black line is between the text zone (red dots and yellow dots) and the table of pinball.

The game switches from video mode 0 to 4 when the red dots begin.

Thanks,

The internal BG2/3 X/Y registers should only be incremented if the PPU is not in Mode 0 and the corresponding BG is enabled.

Because BG enable is latched with a delay of a few scanlines, the internal affine registers only start being incremented with the same delay, even when Mode 4 and BG2 are enabled at the same time.

Thanks for doing the legwork here @fleroviux
