This is unrelated to what RetroBit is doing; but a cool option too for people looking for a component cable solution. I'm not up-to-speed on the technical pieces, but component sounds like a good idea if your TV doesn't allow for VGA.
Component cables offer better separation and a better signal-to-noise ratio compared to traditional composite video cables.
That said, component cables are an analog solution that cannot change the resolution of a digital image. Some Dreamcast games can output at 480p (same resolution as Wii), but other Dreamcast games only output 240p/480i (similar resolution to PS1). Not all modern televisions can support all resolutions. If your TV set cannot support a 240p or 480i resolution, no component cable can change that. Double check which resolutions your digital TV set can support.
On the other hand, a VGA cable is also an analog solution which cannot change the resolution of a digital image. So we would still run into the same problem either way. The real problem here is that we are using the TV to upscale an image that it was never designed to display. This causes dreaded input lag.
What we need is to find a way to output a digital video signal from the Dreamcast. That way we can send 1080p directly to the screen, and the TV set doesn't need to waste precious milliseconds up scaling our arcade games.
Such a device isn't impossible to build; it just takes a lot of r&d. Maybe some fpga can use the dreamcast expansion bus? I would need to look up more info to see how that port works. A more viable immediate solution would be to output your video from a Dreamcast emulator. Then crank up those resolutions high as you like.
