Yeeeaaaah, about that... I'm gonna have to do that in order for the circuit to fit!

Ugh, I can't agree with this enough. I keep hoping to see someone magically find a way to mod the battery pack of a CGB into something that works with a lithium ion rechargeable battery (one out of the DS for example). Unfortunately, it seems like that's never going to happen (or just simply not possible), so a lot of us are stuck with rechargeable AA's like Treble said.

Ok, seems like I have to extend the screen wire thingy. I'll probably have to buy another gameboy color just for the screen wire thing. Or do you think there's an easier way?

"Game Boy: 15 hours, 30 minutes*
Game Boy Advance: 29 hours, 32 minutes
Game Boy Color: 35 hours, 45 minutes

All this made sense and matched our findings compared to last time except the untimely demise of the original Game Boy. For some reason, it only lasted around half the time it did on the first test.

I didn’t think all that much about it until I started editing and uploading the video. As viewers quickly saw, at the moment when the Game Boy’s battery runs out you see one of my children appear and then disappear, nudging the table. One viewer even created an animated GIF with the hard evidence."

I found this yesterday.

Lithium 4 lyfe.

This is a pretty ambitious but unnecessary build imo.

so much, but I like having 3 sets of rechargables and 1 backup set of regulars for my DMG's. rotating energy isn't much of a hassle and the life is decent so that rotations aren't like every day. Maybe once a week.

Ho. ly. Shit.

I never expected CGB battery to be so good

heres another reason:

In 1990 I though they looked worse than slide rules and pocket protectors, how times change...

Your project needs a LED or turbo button mod, seriously.

It looks cooler, that's the advantage. Plus extra space for mods. But wiring together the GBC and DMG controls could be hard, so I don't know anymore. Would be cool though

I was just about to come in saying if he managed this he'd have all the space in the world

I don't want to rain on anyone's parade here, but I see virtually no advantage to doing this outside of the shock value of a color screen in a DMG case.

Furthermore, most of the components in the CGB are surface mount, meaning it would be a pain in the ass to put as many through-hole wire extensions for board-mount components as you would need to do.

I guess my main point is that you will essentially be performing a downgrade on this game boy for a novelty. Unless you're using the extra space you'd get in the DMG case from doing this to add some seriously out there new circuits, like an internal arduinoboy, an analogue filter, a summing circuit like the PISSBox, et cetera, this seems like an essentially destructive mod where you create a "worst of both worlds" game boy.

Okay. Yeah!

Something like that. Yes.
You basically need to move EVERY component that needs plugging in or switching in some way.
