anyway of upscaling pc engine on HD tv? i believe the only way is via RGB mod, then via a expensive xrgb upscaler, but this is a pricey way of doing it? any other more reasonable way and cheaper of getting upscaled pce games? would thouse cheaper china made upscaler do the job? or would it end up really looking bad or worse than using orginal composites?

Tap it for rbg then run it through a rbg to component converter box

but there is no upscale, just signal conversion.
