Does someone know, how to get pixel sharp image in this game?
Because everything is blurred and hard to look at.

The other game fron Piko Interactive, Street Racer doesn't have this problem, I mean the SNES version. It is sharp and crisp.

I included two screenshots, so one can compare.

And I also have sound/music problems, like delay, no sound effects etc.
What should I do?

The sound in Street Racer (SNES) works OK.
