Note from nocash docs about Vertical Interlace: ''"'''Interlace must be enabled to see all lines in 480-lines mode''' (interlace is causing ugly flickering, so a non-interlaced low resolution image is typically having better quality than a high resolution interlaced image, a pretty bad example are the intro screens shown by the BIOS).''"<br>

This suggest that games which eventually need 0x31, 0x02 will be ones that send GP1 commands with active bit 2(Vertical Resolution 1=480) and 5(Vertical Interlace) at the same time. Otherwise image will be cropped, or badly interlaced. FF8 use this on "Published by..." screen, you can notice weird interlacing when subtitles fade-in without command.
