How are you powering the LCD? The LCD requires a separate voltage of -18v. So if you don't go through the regulator, you have no voltage to drive it.

EDIT: Never mind, I just realized what you meant. You are going through the regulated power. But the input voltage of a GBC is 3v, where as I'm assuming you're talking about a DMG which has a 6v input voltage.

They're DC so we're all good there.

I think most guitar pedals are DC, but make sure you don't mix up AC and DC adapters. Things can go very wrong.

I realized after leaving the comment yikes. I'll post results later once I get it all together. Thanks guys.

Again, that's not going to work.

That actually sounds a lot easier. there's an outlet store by me that still sells those things new so i'll stop by today. Thanks!

No, don't do that.

You could get one of those 12v to 3v car adapters for the gameboy color and mod it. Wouldn't even require opening the gameboy.

Its only meant to have 2 or 3 volts going to it.

So I could just wire +5v directly to the positive battery terminal?

A 7805 won't power a gameboy alone. You could just do this externally and use the stock regulator.

I'm not using batteries at all actually. Just trying to power the game boy with a 12v adaptor. I just have nooo idea where the 5v starts on the board.

Re: Does any one know where the 5v in on a GBC is?

2016-12-12T18:32:00Z

it wouldnt make sense that the starting point would be by the batteries. it would need to be after a capacitor.

Re: Does any one know where the 5v in on a GBC is?

2016-12-12T18:13:28Z

The point where it starts is actually what i'm trying to find yikes

the 12v adapter should be ok with that regulator.
have a look at this.

A worker at a video game shop told me you need to have a rechargable battery pack in order for the gbc ac adapter to work, but he did not say if the ac adapter would power it while you play it. I am actually thinking what you are trying to do will not be possible without you figuring out where the +5v starts. I dont think just any +5v point will work because dc does not work that way. so dont just google it. people frontlighting gbcs wont be using the point you need. Im afraid i have too many mods in my gbc to open it up and look around. I cant be much more help than that. probably mostly bs anyways.
