I am, by coincidence, running Recalbox on the Raspberry Pi 4. It works like a charm. Trying to tweak N64 games a bit, I came back here and was surprised to see, that the Pi4 is not officially supported...
It seems that even though it is not supported, it does work. I have not encountered any issues so far.
I will provide some photos later this day.
The weird problem came from not enough current. I switched the power source and then everything went fine. Though the Pizero is highly not recommended for any Recalbox project. The menu is very, sluggish if the output is an average Hdmi monitor with 720p. The pizero should only be used for handheld tft displays with lower resolutions. Then it works fine. I think I will do a Gameboy Hack, if I find one. Or maybe use an old nes controller.
Hi there, I am doing a new thread, because the issue doesn´t seem to have appeared yet. This is my setup:
I have downloaded Recalbox 4.0 stable, then I powered up my PiZero. At the boot screen it freezes. If I plug in a keyboard however, it starts normally. Bluetooth and WLAN are working, but if I use the webinterface to copy roms, it is verry slugish and in 9 from 10 tries, the rom upload aborts.
Restarting the Recalbox ends in freezing againl, unless I plug in a keyboard... .
I have tried to use an unpowered USB Hub, as well as none at all. Without the keyboard it is not working... .
@Seramis D**ned, I am stupid... I downloaded the beta instead of the stable Github Version. Guess this must be it.
@Seramis Ok this is weird. Recalbox only starts when a keyboard is enabled, even though I have a Bluetooth Controller working that fits perfectly for controlling the overlay. No Keyboard, no Recalbox on Pizero. Any ideas?
@Seramis Solved it myself. The issue was soley usb port related. The Pizero doesn not seem to like two devices capable of giving power output. I have used a china hub without energy and it works well. Curious thing though.
Ok then, my Pizero has arrived and Kano works like a charm. I have just tested my recalbox build but the software doesn´t start. It hangs on the boot screen forever. So I started fresh and got myself the image from Github, erased my sd card with the formater and placed everything inside. However the Pizero still hangs at the bootscreen.
If I put the very same imgae in my pi3 it works. What´s wrong?
Ok here is another thing I need a display capable of displaying 1024768 or higher. It should be cheap. Unfortunately there are only 1024600 devices out there. Touch would be nice but is not Obligatory.
@Substring I did. I thought about such a thing. Then it is ok I guess.
Hi there, yeah, I am considereing different budget projects and I think I have a strategy to trick the parents into buying all salami tactic style. But it is well worth the experience and the money.
I consider them buying either a PiZero or a RPi3, and I will explain them the basics (as well as the differences between the two) beforehand. Then I will make sure, that we are going to build a system on the basis of kano. We are going to add everything that we see fit or appropiate. So the system gets larger and larger but only with meaningfull parts.
We may add a screen, if desired or a small audio output system. The parents will receive the costs beforehand but they can decide what their children need and what they already have at home. If someone doesn´t want to by a screen for 30-40 €, the child may also attach the rpi to one of our screens at school. There is an adapter issue there, but we can also ssh into it, so no problem there.
Some may want to build a spycam or sensors or an internet radio. The Recalbox is my giveaway at the end of the year. We will also talk about copyright there, so that they know what to expect and what not.
At topic there:
I bought a five inch screen with touch, and I know that it doesn´t work with recalbox, but I am using raspbian too and I thought it would be nice to have as an addition. I have managed to alter the config.txt via putty and I also changed the recalbox.conf via the web interface. However I do have an issue with N64 games, wich is only minor, but there. I have also read a thread for that specific display which can be found here in the forum, but the Thread Starter doesn´t seem to use n64, so the issue is not explained there. I think it has to do with the native solution though. So here is my display:
http://www.waveshare.com/wiki/5inch_HDMI_LCD
By the way it is ok. You can´t do anything wront here. The nativ resolution is said to be:
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
This is the tutorial I followed:
https://github.com/recalbox/recalbox-os/wiki/TFT5-Screen-HDMI-(EN)
Works like a charm, except for N64 games.
I wrote this in the recalbox.conf:
n64.core=gliden64
n64.emulator=mupen64plus
n64.ratio=16/9
n64.smooth=1
#n64.videomode=DMT 4 HDMI
n64.videomode=default
This results in the following: N64 games start in 4:3 but there is an edge right of the display where it isn´t used. It just stays blank. Altering the conf results in N64 games not starting at all or the screen turning white. I tried different DMT Modes except, resulting in either crashing or having weird formats where some parts are missing.
Is this due to the native resolution of n64 games and is there a solution to this? It is not a big issue though I could live trough this.
Works perfectly with all emulators except n64. Keeps crashing.
I wrote this in the Recalbox.conf
n64.videomode=default
@Substring No specific needs. We don´t need large resolutions. But on screen text shall be readable, HDMI plug and play (to make it easier), if it has touch function ok, but this is not mandatory because we will only need it as a screen. I intend to make them do their own boxes. A DIY PC for the young ones and a retro gaming console for the older ones.
LOL... I had to look up OP, now I know 
Today school freaked out about my project class. Parents have called my school to tell them that their kids are interested in stuff, they never would have thought they are capable of. Now I was handed a class 5, 7 in addition to my 10 starting in February - so in about two weaks from now. There is no concept but we are allowed to do soldering and much more. I was encouraged to help them realize their own project, no matter what that may be (some girls are doing a smartphone case with a pizero and lights). This came out of nowhere because normally video gaming is considered a bad thing. Thank you very much for the vectrex project, this will become in handy for the older pupils.
I think it would be nice to built some cool retro gaming consoles with serious games for the little ones. Their own ones. This is going to be fun.
Oh I need something:
A really cheap hdmi monitor for the pi, large enough that you could to some programming, I am thinking about KANO here. But not too large. It should be powered in the same manner as the rpi via mini-usb. Any recommendations? Cheap it must, Yoda would say.
https://kano.me/store/eu/products/kano-complete
What about this here?

I see that I need the GPIOs here to get the touch function right? The other model, which costs 3 € has the option that you will have the touch function via usb. Are there any disadvantages? I would rather go for the GPIO version... .
This is already a part of the box, but a nice addition for others reading this! Thanks.
I have just realized that I have an Adafruit Touchdisplay lying around, doing nothing at all (I have used it for a raspberry pi Camera, to play around a bit.)
It´s this one : https://www.adafruit.com/product/1601
I am wondering if it is possible to built a gameboy with this? However I also want the gameboy to be connectable to a tv and then get the normal hdmi output. The kernel adafruit provides runs on an own raspbian image, so I have to find out how to implement this in recalbox. The condition should be: If no hdmi is plugged in, the rpi should send the image to the tft, If the hdmi is plugged in, the output should go to the tv. (In theory this has also to be possible with the rpi 3, so you would have a powerfull mario kart n64 inside your pocket.
This is only about the programming, if that is the right word, not about fixing it inside an old gameboy, which will follow if this is a success.
I have searched the forums as well as the internet, but it seems that all tutorials are all about just having the tft enabled, which will disalbe the hdmi output. I have the nintendo switch in my mind. How awesome it would be, to have a retro-gaming consolde in your own which you can also share with others? Any hints to how to´s are really appreciated. I am a linux beginner and this is best desribed with cooking: I can cook with recipes and I am really good at it, but I am nowhere near inventing my own recipes. I got a grip for it though, I know the basics.
I ordered at PiHut and got myself the mega kit with everything one needs. Unfortunately my class ends a bit sooner as planned but I am going to get a new class. So for the current we are just building a retro gaming station as easy as possible because we only have 6 lessons a 45 minutes left and I see that gpio tricks aren´t a good idea without the theoretical knowledge about them.
But: I would like to do a more ambitioned project with the next course. I am wildly fascinated about the gpio pins myself, I can solder but electritians would wildly go mad about my work, because it´s not too beautifull. Consider me a beginner with electronics (I can build a pc, I know very much about Software, but electricity is something I tried to avoid so far.)
One here had the idea to use old controllers and wire them to the gpios of the pi. I think this is exactly what we should be doing instead of buying cheap china ware (nothing against those, but I feel this is all about trying to do as much on your own as you possibly could).
The thing is: I don´t want to solder at school. The group is pretty large and I don´t feel comfortable with that. Is it possible to use a breadboard instead and what do I need to buy for that? Again, this needs to be as cheap as possible!
I have made a list but I am not too sure about this. We are going to use the RPI3 and the PiZero, depending on the portemonaie of the pupils:
This is the T-Cobbler Plus (Does it work with both the RPI and the Zero? The pins look the same to me.
https://www.amazon.de/Sintron-T-Cobbler-Extension-Rainbow-Raspberry/dp/B00NWA2AS0/ref=sr_1_1?ie=UTF8&qid=1484646900&sr=8-1&keywords=gpio+to+breadboard
And then a breadboard or rather a complete set like this here:
https://www.amazon.de/Sintron-T-Cobbler-Extension-Breadboard-Raspberry/dp/B00WSXXLZS/ref=sr_1_5?ie=UTF8&qid=1484648086&sr=8-5&keywords=gpio+to+breadboard
I am not a pro with this and I am going to test this at home way before going into classrooms with this. In my eyes this could serve as testing out the gpio setup, before doing soldering right? I imagine them doing this at class, so I can see if their setup works and then I will solder their setup at home.
@voljega Sorry I'm a non native speaker, I chose the wrong word. You are right. The thing is that we program robots on screen and they never see it happen. They are also incredibly afraid of dismantling hardware.
They aren't allowed to break things no more..., something incredibly wrong here in Germany. One has to see how things work in breaking them apart, this has to happen as a child. This isn't about money, there are things for children which are meant to be broken, but parents tell them to be overly cautious with everything. This drives me nuts. :-).
Anyhow we got things going and I am surprised how well everyone at school liked the idea. If this goes well I will publish the concept for free.
Getting the pizero is still a thing, people are afraid of ordering elsewhere than Amazon.... Maybe I have to buy for the whole class.
I have to say that I still can't believe their reaction that they actually admire old games being 15 years old and growing up with CoD. Some girls like to do a smartphone casing with LED lights, we will fetch an Arduiono for this. But many go for the pi version, I will have a look at kano first, see if they aren't to old for this.
Hm OK:
The pi zero can be bought at pihut. What essentials should be bought to have this as easy as possible?
Which adapters shall I also oder? Is this a thing?
https://thepihut.com/collections/raspberry-pi/products/raspberry-pi-zero?variant=14062715972
The goal is just to help them create something valuable to their own with as less help as possible and without the fear of breaking something costly. Furthermore the pi is so flexible that they can move to other projects on there own. Computer Science is so boring here in Germany. You never get to see your results, it all happens on the screen. I want to do a bit of programming first, work with raspbian, get it going via the terminal. The gaming console would happen at the end of the year, as a gift so to say.
Where do you by the zero? It is neither for sale at amazon, nor at reichelt. Ebay wants 20 €, I think this is not as it is intended.
