Problems with my game

[STGraves]

Hello, I have 3 questions, first is there a possible way to change the color of the ball to make it outstand form the playfield?, second I have a problem with the playfield the game runs normally and plays the same but the top and bottom row from the playfield flickers, and changes size and color, how can I solve it?, and third how can i adjust the size of a sprite because the sprite of the second character appears partially, is missing some parts.

Thanks

I think the ball has to be the same color as the playfield. The reason your sprite is partial is because the maximum width a sprite can be is 8 pixels. You can use NUSIZ to stretch the pixels, but even still it would still have to be less than 9 pixels wide.
