I'm having a bit of trouble with one of my games. You know how some old games have the flicker effect? Well, I was playing King of Dragons yesterday, and as I started out, there was quite a bit of flickering with my character and the enemies on the screen. I'm kind of used to this, so it didn't bother me too much. However, it did become an issue when, at certain points on the screen, my character and the enemies would completely disappear. If I kept moving, I'd eventually get to a point on the screen that would make them reappear, but it was very annoying. This became a horrible problem when I came to the boss fight at the end of the first stage and both my character and the boss were invisible. I took the cart out, cleaned it with alcohol and Q-tips, and tried it again. My cleaning apparently did nothing because the same amount of flickering was present, including the invisibility with the boss at the end of the first level.
I had been playing as the same character (the warrior), so I tried playing as another character (the archer). Fortunately, I was able to see and beat the boss at the end of the first level, even though there was still a lot of flicker happening throughout the whole level. BUT....unfortunately, I got to the sixth or seventh level's boss as the archer and the same problem happened again. My archer and the boss became invisible, rendering the game unplayable.
I don't know if this explanation makes any sense, but if it does, can someone tell me what the problem is? Is it a problem with my cart, or is it my SNES that's the problem, or could the problem be caused by the plasma HDTV I'm playing it on?
