I think I've exhausted Google search. I took a Super Mario 2, replaced the Roms with I think Loopie Mario 2 hack. Tested in the emulator it worked. I copied and filled the ROMS, they verified okay. I have placed in my NES and welcomed with a giant red screen.

I have one other game, Duck Hunt and Mario 1. It works fine.

Thanks, best regards

Which emulators have you tested in?

Solid color screens tend to be due to bad pin connections. Saying this from experience with my NES and corroded pins. Make sure the board and solder connections are good, continuity tests if you can.

Edit: reading further, it may also be the lockout chip, especially since using a modified ROM.

Lockout chip only deals with the blinky thing, where it resets every second, not with any failing code.
