Is it normal ?? (on Gradius II gofer and Parodius)

[carlosemandrade]

Hello all.

I bought and tested yesterday two konami games : Gradius II gofer and Parodius, both runs fine but i noticed a little strange thing that occurs on both games

- Gradius II only on opening sequence (1985 ... -> 1986 ...)
- Parodius> End of stage 1 (only stage 1 to 2. 2 to 3 all ok)

In both cases, a small amount of "garbage" or random colored pixels appears on top of screen for a small period of time, like this:
           .             .     .            .     .    ..
      .        ..    .          .            .        .      ...




Other games i have (Twinbee, Naious and Castlevania) are all ok too.
