That's looks great, I'm doing the same sort of project but mines a server not a retropie system. Mine been half done for like 2 years now lol. Im also using a banana pi, due to its sata onboard connections. Im also tempted to connect up the fans lol.
I got a couple of questions.

Does the power button still work on the Xbox? I've been trying to use the original board.

What did you use to do the front usb? 2 female usb cables?

I did not bother with the front power button, I just glued the button so it will not move and push on my LED behind it, Plus I have the power button on my 5v input on the back.

The front USB ports I ended up using a USB hub which was lucky enough to fit, But realistically just short USB extension cables will do the job like i used with the memory card port USB.

Something like this would be ideal:

Thanks alot they look like they would do the job, I think I'm going to finally finish my one off lol. Hoping to use the power button tho. I've learnt alot from doing my GBZ.

It should be fairly easy to mount a small switch behind the button on the metal casing, but getting the LED to shine through might be hard as well.

Just finished the audio, works well

My 3 port USB hub is unfortunately USB3.0, the size is perfect but it requires additional 5v feed, but the big thing is the Pin's are small to solder onto so it add's some complexity.

Extra buttons are done:

I had to trim down the GB Cart reader, almost back to the pins for clearance:

Hi, your GB0 looks great already!

Quick question, I saw in another topic that you are using the XIANJIE 3.5" screen. Is this one working ok? No extra mods needed to get it to work?

I've emailed the seller for some info, hope to hear from them soon.

I'll be following your build!

Thanks, Max

Hey Maxxerd,

The screen is working off 5v, I had to solder the single wire as per below, My solder job isn't my best work but its working:
I did make a bad decision of fitting the screen before drilling my extra buttons and the drill grabbed the ribbon and damaged the back lit. Just waiting on another one to be delivered.

See the 2 wire trace ribbon on the left, that is what I damaged, without it the screen has no back lit. Unfortunately I couldn't repair it. New screen should be here in the next few days.

The screen seems very good quality, there is no contrast or settings to change on it but I am happy with the price and quality so far.
