Can the video signal of all Nintendo games be deinverted on the board itself?
I've seen people offering ROMs or something for Donkey Kong boards that you could use to replace the original ROMs and the board would output normal video for use with a normal monitor, rather than inverted video for use with a Nintendo Sanyo or Sharp monitor.
Can this be done for any Nintendo board, specifically Punch-Out and Super Punch-Out? Would it be a matter of changing the code for the color PROMs and burning new ones, or is it more involved than that?
I know that you can use inverter boards with normal monitors, but that is an analog inversion, right? And as such, wouldn't it introduce some loss? I would think it would be better to have the problem corrected in the digital domain in the first place, and skip extra analog processing hardware.
If this can be done, I'm pretty sure that folks like Jrok, Spaeth, or 2600 (and probably others around here) could do it (it isn't something I could do, plus I don't have a burner). I'd be willing to pay if someone could do it. I want to put new monitors in my SPO machine.
