| Ok, so here's an idea i've come up with.
After an extensive tidy up through the various cupboards in my room, I found a few consoles that I never actually use any more, and havent for the past 5 or so years, including a SNES, my first N64, a gameboy, a gameboy pocket and a GBA. Now, im kinda interested in starting working with electronics a bit more than I usually do, and I got an idea. Would it be feasibly possible for me to take out the innards from a game boy, and wire it in a way that the SNES's controller inputs are linked to the game boy controls, and the sound/video is linked through composite (the snes's video output) to a tv, or such? Basically, what I would like to achieve is a SNES, but a SNES that is essentially a game boy. Kinda like a super game boy, and yes I have one of those. But if this is possible for me to do, I would like to do it just for the experience it would give me. So...is this an impossible idea? Or is it possible for me to do? And has anyone got any useful links/sites that I could make use of? |

| it isn't impossible but you have a large task ahead of you...
you have two main tasks--translate an SNES controller signals into GB control signals and translate the GB video output to TV instead of LCD. Fortunately, for you all the other hardware remains intact. Probably you should start out finding what signals the SNES controller sends out and what signals the GB want from it's controller. Then, build a circuit that will do the translation. After that, you will want to find a way to get the SNES controller to sync with the gameboy--something I'm not sure how to do... It should be something similar for the GB output to TV... |

Originally posted by neotransotaku Yeah thats what I'm thinking of doing. But, I just cannot find any schematics or diagrams about the game boy's display connections, and how it relates to/how it can be linked through a composite signal. And the about the syncing, I never really thought about that before 
EDIT - ok, I've found a schematic of the LCD display at http://home.hiwaay.net/~jfrohwei/gameboy/gameboy2.gif And also found this bit of info here: 'Is it possible to somehow hook up a GameBoy to a TV? It is possible and has been done. Many people have seen these as the demo machines that are often found where GameBoys are sold. These are no longer made but they were know as Demo Boy II's. The main problem is that the horizontal sync in the GameBoy is ~9.2KHz where TVs require ~15.7KHz. This lower frequency sync can possibly overheat & burnout components of a standard TV. So there is no simple circuit for connecting a GameBoy to a TV.' Does anyone know how it would be possible to overcome this problem?

| You'd need a very specialized circuit. I think the SGB's workaround was that border it added. The GB's screen is smaller resolution-wise, hence the lower frequency.
Adapting the controller is probably possible but I wonder if it might be easier to just rip the logic bits right out and run wires from each button to the traces on the GB's mainboard where its buttons connect. 
Really I'd suggest you learn either Z80 or 65816 ASM and turn them into GB/SNES development systems, wired up to your computer such that you can have them download and execute code. |

Didn't really estimate how much work this idea would result in, but I will carry on, determined, at least until I end up with a working console or a collection of useless circuitry. |

| Take a look at the hackaday.com site. The guys on there seem to know how to do thar sort of stuff. One guy made a portable N64 which isn't bad. | |||

| FUCK YES!
http://www.konlabs.com/articles_data/gba_console/index.htm Just what I need. Looks like theres no problem connecting a GBA up to a tv/controller input. |
