GB player for NES? Is it possible?

[toredauei]

Does anyone know if it would be possible to make a GB player (think supergameboy but for the NES) I dont see why it wouldnt be possible. The original gameboy is an 8-bit system anyway is it not? I would love to have the ability to play my OG gameboy games on a full screen in the original shades of green with no borders etc.

what do you guys think?

Technically I am fairly sure it is impossible:
NES Processor - 1.66mhz (overclockable to 2mhz)
Gameboy Processor - 4.19mhz

what if someone were able to fit the guts of a gameboy into an NES cartiridge and have the NES somehow read the signal?

That is a question I cannot answer.

what would have been the point? that thing would cost more than a gameboy to make.

EDIT

oh you are talking about making something like that today. yeah I guess the nes pad would be great for gameboy games. I think it's easier to make a gameboy that connects to your tv, and to an nes controller, than what you are proposing

Nah, I'm pretty sure it would be possible. You would just have to have the entire Gameboy hardware contained in your "Super Gameboy" cart. You would then need an extra video processing and a buffer in the cart to bitmap the screen in a format the NES's PPU can read easily. Every screen could then (I think) be drawn without using the sprite handling on the NES.

I'm not sure the NES color palate has four different shades of green, though. That might be a problem.

Also, you would probably lose a sound channel.

You would probably still have to have borders around the screen, too. You could do something in hardware on the cart to upsample the screen by a factor of about 1.5, but it would look like total crap.

Would all of that fit into an NES cart? You could save space by using a gameboy pocket. Does the NES color palate have four shades of any color? The loss of a sound channel isnt that big of a problem as you could just incorporate an external audio jack if it was really important to you.

http://en.wikipedia.org/wiki/Super_Game ... successors

The Super Game Boy was the successor to Intelligent Systems' Wide Boy 2 (which connected to the Famicom or NES). One difference between the Wide Boy and the Super Game Boy is that the former did not use any part of the Famicom/NES other than the video memory. Even the controller (a single Famicom controller) was hardwired directly into the Wide Boy. The Wide Boy would continue running even if the reset button was held down on the Famicom/NES. The Game Boy had twice as many tiles as could fit in the Famicom/NES's video memory, so the Wide Boy had to refresh the Famicom/NES's video memory halfway down the screen.

I remember reading about one of these adapter in an NES cart style things for the NES, but from what I can remember like all things rare and NES it costs more that a nice used car.
