The error comes from src/devices/machine/generalplus/gpl16250soc_video.cpp line 1152.

The variable m_yirqpos = 0, so it passes -19 to time_until_pos, causing the assert.

The authors will need to address this due to my unfamiliarity with how this is supposed to work.

Be careful while testing, a 10-second run causes a 1GB error.log
