There is no driver for the backlight. Do you get a bright blue screen on power up?

You turned the backlight on, did you ? (The switch turns it on) Did you try powering directly or through the Pi ?

for those wondering, I decided just to order one of the gameboys from 1up just to see. Cost me $469. From oder to delivery was 3 weeks, 2 days. I opted for the murdere'd all black version since I already have my gray one. It looks much different than the original render they showed me. They managed to stuff 12,000 mAh into this thing! Two 4,000 stacked, wired in series in the battery bay (uncut) and another longer, flatter 4,000 mAh in the cartridge slot. They also put a push button test module at the top to show battery percentage. Kinda cool, Charge port at the very top. The screen looks way way better with hdmi than any of the 240p screens I've used. Night and day to be able to read the text.

I give the design a 9.5. Their design is great. No glue, everything is wired and fits and it's nice and clean. As far as build quality, I give it a 6.5. The custom board they used, looks like it was made for a built in atmega 328, and they hacked the edges of the board off with a Dremel or something to fit an Arduino with a newer 32U. then they just tapped into the leads on the board..... It works, but...meh... and whoever built it took external USB for the Arduino, you can see the wires in the picture. I'm assuming the "body" of the unit (screen, pi and proprietary PCB) come assembled, and he didn't care to disassemble it, so he took usb from the outside. Again, it works but...meh. One of the thumb sticks stopped working after two days, when I took it apart an additional wire to a battery lead, and one of the usb wires to the male usb plugged into the Arduino came undone. Took me the better part of a day to trace everything around and figure out how it all worked. The D-pad is programmed as an actual hat switch, which isn't common for a four way I didn't think.

It didn't even dawn on me to take pics of the inside when I had it apart, I suppose I will take it apart again eventually, or if anyone is even interested to see.

Anyway, I loaded Rey's image on it and have been having a blast playing ocarina of time, which runs amazingly well I might add. The trigger buttons feel really nice and comfortable to hit. It does get hot, but in game I haven't noticed any slow down. It does tend to slow down a little in the menu on Rey's image. Played off and on for about a total play time of 3 hours and the back was still blinking 40%, not bad. Now that I have the inside sorted, I may just keep it around for a while. :)

I'm working on a similar project right now. I removed 2 of the 4 USB port of the Pi3 and had to REALLY trim the case down for the pi + HDMI screen to fit (mostly due to the un-compressible HDMI-HDMI adapter). I will use one of the removed usb port to wire a AIO by Helder (I'm waiting for the board to continue the build.

I would be very interested by photos of the inside of 1up's work, especially how the pi3/screen sandwich works.

Hey, I got this 3.5 HDMI screen and I have a trick to share... If you don't define the resolution in the config.txt and power the screen along the rpi zero, the detected resolution is lower 4:3, but if you restart the rpi zero, you will get 1080 and 16:9 ... I'll get some screen shots of the difference between the two( crispier image on 1080).

In short, you need to power up the screen 4 seconds before the rpi zero to get this resolution... ;)

If you want it to run at it's native resolution (Crisp image) add this to your config.txt:

hdmi_cvt=480 320 60
hdmi_group=2
hdmi_mode=87
hdmi_drive=2

I took a video, to show the difference if using the highest resolution, it also fixes geometry issues...

I found this screen on Amazon:

In the reviews a guy made a GBZ with it. I tried to reply to his comments with no avail.

Here's his photo.
