I have two copies of PAL Kirby's Fun Pak (Super Star in US) for the SNES and they both seem to suffer from odd graphical glitches. Small distorted lines appear whenever Kirby attacks or enemies appear at the bottom of the screen. I've cleaned both games as well as my SNES (which has been modded with a 50/60Hz switch and no region lock) but the problem remains. Is this a common problem with Kirby's Fun Pak or have I just unfortunately got two faulty copies?
Thanks.
EDIT: Some pictures. It's kind of hard to show but basically the little lines by the fish. They constantly flicker about. This happens every time an enemy is in that part of the screen.
