Just so we can get an idea of how much better it is. :D
Here, I did a quick one with Donkey Kong Country running on it: https://youtu.be/INGlAf0Ny2w

It is much better than the AV, especially in when the picture is NOT moving. In my first build I'm using one of those 3,5" AV screens, and I like the quality ingame, it's a bit more than okayish :)

One more advantage you gonna enjoy with this screen: It is 5v ready out of the box!

Definitely better! Will you be taking the touch screen off?

So how are you getting sound? Does the pcb have audio out?

Don't contact me about obtaining my board files (as you will not get them). If my Boards or PCB Kits are sold out, they will be restocked as soon as I can get them and there is demand for them. You can join the mailing list on my Website to be notified when they are available.

I still don't like the alignment, it's not centered.
Wonder by how much we can adjust that, not talking about the pixel mapping but the black border to the side...

On a sidenote we get to use all of these now; http://www.cnx-software.com/tag/olinuxino/
Some images can be found here; http://www.retrorangepi.org
Opens up the possibility of nice n64 + psi games on our "zeros" =)

I was thinking I might just flip mine and edit the config.txt to rotate the screen.

Flipping might do us no good, it's 1 side (that would go to your left or right).

However we can shave of a few mm of the backboard and compensate a bit.
Like for my case I'm working on now it pretty much already fits if not directly... now we know you can remove the backboard that allows for some flexibility. Don't know how it works out till I get mine in. Already got a mail my payment had arrived but now it's Chinese new year and that means a week of waiting before it actually gets send out.

The screen PCB comes with a 3,5cm phonejack... I just desoldered it already since I gonna go for wires instead of using a plug...

Here some more pictures after I have shorten the PCBs (screen + pi) and some tries to fit everything in:

If I go for the 180º HDMI plug, I will have to remove a lot from the inner of backside of the case, the room between the PCBs can be used for a little cooler/fan... Problem will be than, that cambles shutdown PCB won't fit anymore...

At aliexpress you gonna find a lot of angled HDMI connectors, probably it is possible to come up with a better positioning by using a combination of these, see https://de.aliexpress.com/item/20CM-FPC ... 52231.html

Some more pictures of trying to make the pi fit with the screen into the case, it's just a quick an dirty proof of concept:

With this positioning I need to come up with a new solution to keep the case closed with screws... The usual positioning of the L/R tactile switches is also lost... With a pi0 it would be much easier :)

How much modding do you think it would take to fit this screen in with a pi zero and an adapter like this http://www.ebay.com/itm/381827326709

and a cable like this:
