Does anyone know what the cause of this might be? The characters in the attached photo are scrolling across the screen. The machine powers up, makes the jump sound, and these characters begin scrolling.

Thanks!

I decided to pull this board out and start playing with it again.

One thing I noticed is the windows on all of the ROMs are uncovered; no stickers. All of my other boards have stickers on the ROMs. Don't these need to be covered to be protected from UV light?

Sort of. Covering them will prevent issues but they often go uncovered for years and years and have no problems, even if exposed to light.

Ok. Noted. I have no way of testing my roms, but I suspect I can pull them and have them tested and/or burned again. I've used hobbyroms.com. Any other suggestions on rom burning, in case he's busy or otherwise unable to do it?

Thanks.
