Pi Zero W GBA [WIP]

[Alex4U]

I don't know whether or not to connect the display to the HDMI

You could solder on the lcd pins and try somehow to make a hdmi entry. There must be another way, but I really don't know. I did this one time with a Virtual Boy, but sometimes it worked. (Not HDMI, RCA)

That is not necessary anymore. The screen I've got will be connected via the GPIO pins.

I'm really curious how does look it .w.

:/ Please read all my posts so far. I don't like to repeat things this soon. Thanks.

Oh I'm sorry I didn't read correctly ;u;

I have the expertise to save my $$$ that's why I don't want to take the easy way. Plus I plan on fabricating my own custom PCBs anyways.

I made a mistake earlier about the batteries, I said "5A" as in Amp when that should have been 5000 mAh, which is completely different. The more mAh the better, I just don't want to push 5A through a Pi Zero W because it'll kill it instantly. And according to a chart I saw on Pi Zero power consumption, 1A should be enough, 1.5A would probably be ideal.

the pi's are notorious for having an undervoltage problem. make sure to snag a 5.1v supply from adafruit.

That's taken care of already.

The MicroSD card just arrived.

Battery just arrived.

Screen arrived today. All that's left is the PowerBoost 1000 and Pi Zero W.

I've removed the connection pins on the screen because they took up to much space. I'm wondering if I would actually need this mini SD card slot... More than likely it's for debugging or flashing firmware.

Got my Pi Zero W and the PowerBoost 1000. Time to build it!

I'm having problems connecting the correct pins from the screen to my Pi, details are here https://retropie.org.uk/forum/topic/12705/pi-zero-w-gba-build/18.

 

[TechieAndroid]

Nevermind I figured it out.

 

[TechieAndroid]

And... it's not working.

Okay so I've got and setup the new screen but I don't like it at all. I don't know if this can be tweaked (probably, I just haven't tried yet) but the screen's dpi is messed up (everything it too small, which is probably just a wrongly set resolution from before when I had a tv connected), and the other major problem is it stutters so bad I can't play any game on it (it stutters, drops frames and tears).
