Describe the issue

There is an odd behavior concerning Tokyo Road Race and HDTV modes in OPL's GSM If not using "Emulate flipping field", then you will only get a black screen after the video mode selection screen (between PAL and NTSC), but you can still hear the game run just fine, if you do use Emulate Flipping Field mode, 2D textures start getting overly jumpy, which isn't an unknown issue but it seems to affect this game a lot more than any other (3D rendering seems to fair better but the 2D textures are really jumpy), but once entering gameplay, if you use the interior or bumper views, the rear view mirror has an odd "fading" effect, which resets itself every couple of seconds.
