Gameboy Pi (Rethought the concept)

If you want buttons look here.

the ones i got are the OMTEN D3, they are rubber topped and the height is pretty much the same as the rubber domes on the stock GBA. This will allow you to make your own PCB or substitute, and still get the retro feel of a standard GBA

Thanks man I've already got my tactile switches :)

To anyone interested Kitsch Bent do some pretty awesome little button PCB boards that I'm gonna be using they're really good! and so small so pretty good for smaller projects.

They are perfect!

SO IT BEGINS!

@monstermadeofman good luck! I might be able to make some headway on mine soon!

Amazing concept OuO I can't wait to see how you do! Best of Luck!

My only recommendation is to avoid using pi 3 if possible. Seeing how you want to emulate 16 bit and lower, the pi zero is definitely the way to go. It's cheaper, smaller, easier to power... it's more convenient in every aspect. I say this because I ran into a huge problem with my handheld using pi 3, because it has complicating power demands that the popular powerboost from adafruit cannot handle. And I'm not even able to play anything the zero couldn't handle, because it would require overclocking it the thing.

Other than that, I don't see any difficulties in your project. The PiGrll seems like a solid starting point. I used those buttons on mine and they are awesome!

Everything looks promising! Good luck with everything.

I did put up the sop dude that I'm using a Pi Zero. Wouldn't even manage to get a Pi3 into a GBA case, no where near it with battery, and other boards that I require. Christ I'd need to convert an old GBA carry hard case to do that. (I've seen something similar done with a Gamecube hand held).

I've already used a Pi3 for console build. And I found it pretty decent for N64 emulation, admittiedly I'm only playing mario 64 and DK 64 but they are all I pretty much want.

I was aware that the Pi3 would struggle with the battery demands, found that out by looking into the Pi GRRL from Adafruit as they specify that you can not do it with a Pi3.

The main things I've bin running into uncharted waters is trying to keep the exterior case pretty much original, you know cosmetically the same. But looking at some DMG Gameboy Zero builds has given me some ideas.

I've gone through 2 different screens at this point. but I've finally settled on one that fits the casing and size constraints with the driver board.

I've got some nice little electrostatic button pads coming that will work with the original GBA buttons. and I'll be using some little momentary switches hidden on the back for the X and Y.

I mean all in all this is quite a big project, I'm really coming to grips with the hardware side of things thanks to a combination of other peoples projects on here, the Sudo Mod forum and people that are kind enough to put walk throughs on Youtube of their DMG build.

How's your build going? I just bought a broken Gameboy Advance from eBay for $12 shipped that I'm going to be taking apart to see if/how things might fit.

@obsidianspider

Ended up dropping it for a bit if I'm honest. I found someone online who is making a custom PCB for a Pi Zero in a GBA. But they aren't on sale yet.

obsidianspider

@monstermadeofman Which one is that? The only one I've seen for sale is the Game PIe Advance, and that's $80 plus shipping.

@obsidianspider

Relevant to your interests I believe sir

Stumbled across this and thought of yourself

@monstermadeofman Already bookmarked! I want to add X and Y buttons to it, but first my GBA needs to show up from Hawaii. I'm not averse to the custom PCB idea, but I really don't want to spend $80. What "other" custom PCB have you seen floating around? The only other one that I've come across is this one that I came across while browsing Reddit but I don't have any info on the maker.
