[Sega Mega Drive] Graphics issue with certain Public Domain ROMs

[freq-mod]

Describe the issue
Out of this repository (https://www.planetemu.net/roms/sega-mega-drive-public-domain?page=0), there are a few ROMs that fail on emulators. On ares, prime example is Flavio's Raster Effects Test (PD). On real hardware, this ROM displays an image of a Native American man, hitting Start button cycles between different raster effects applied on the image. On ares, a gray screen with black lines are displayed instead.
