Hey guys,
My arcade gaming rig is a Supergun connected via RGB to a Sony PVM monitor. I've played both "Shinobi" and "Final Fight" on this setup, and all works well.
I recently got a Data East "Robocop" PCB, and while everything seems to be working well on it, the image is slightly stretched in the vertical axis, making it so that there are rather noticeable black bars on the right and left sides of the screen.
I don't think it's an issue with the monitor (v-hold does not stretch the image), as it plays my other games at the correct aspect ratio. Is there any logic or components on the board that could have an effect like this if it was broken or old?
