commit: 5ae3cb8

As the main character moves around, he leaves ghosts behind. This can be seen in scene 1, where the character on the ground should not be visible. The one climbing up the stairs is the right one.

Maybe the sprite table is not emptied correctly?

Should it be emptied even if the sprite pre processor is not used?

On real hardware the parsed sprite table is emptied, it depends on how you have implemented the parsed sprite table scanning.

Currently, it is only cleared when the pre-processor is used. I see that we need to clear it each time then.
