[MD] Striker: flickering lines on the field #626

As it turned out, sound is not the only problem in this game.

There is flickering lines on the field. Look at the left side, where one shade of green changes into another.

Have you tested on Genesis Plus GX? Looking at the code it mentions Striker as one of the games where CRAM can change on hblank

No, I haven't tested it. A good finding.
