So I bought an NTSC NES motherboard so I could play games in 60hz and full screen, like you do. However after hooking it up I learnt the TV in my game room apparently supports 60hz but NOT actual NTSC colour, so I get a stable full-screen image but just in black and white. I didn't know this until now because my NTSC consoles happened to be hooked up via RGB and the 60hz consoles that are composite/RF are obviously just PAL60.
I've found these on ebay:
but I'm worried about how well an £18 adapter from Hong Kong can do this kind of conversion.
Has anybody overcome a similar problem before? Ideally I'd like the end result to still be full screen and it still being 60hz is a must.
