Summary 07271: genesis and clones: Missing borders
Description The sometimes-colored borders output by real hardware are missing.

Real hardware captures, for reference:
NTSC

PAL
Steps To Reproduce Sonic 2 shows a blue border right at the title screen, so loading it may be the fastest way to check it out.
Additional Information Attached are a picture of a Sonic 2 bootleg similar to `sonic2bl` showing the borders around the screen on a CRT arcade monitor, and a comparison of MAME's output and BlastEm's, with the visible borders changing colors mid-screen.

These can also be seen in other related hardware such as the SEGA Radica systems:
