I am working on a friend's Punchout. Does anyone know which eproms on the video board are the player sprites.

The player shifts to the left and changes color. These issues disappears when the game warms up.

The problem has been isolated to the video board. It is not the color proms nor the eproms they have been checked on a working punchout.

Freeze spray doesn't seem to affect it.

So if anyone know which eproms on the video board contain the player sprites. I would appreciate the heads up.
