Last Saturday I got my ordered Raspberry Pi 400 Kit and I tested it today.
The first thing I tried was installing theXemu emulator. 
It runs great and for about 100 EUR for the set (or 70 EUR for the Raspberry Pi 400 only) it's one of the cheapest possibilities to have an MEGA65 ... (okay, it's only the Xemu emulator). 
Ist das eine Linux-Installation oder läuft das über den Browser?
Kenne mich leider mit Linux gar nicht aus 
Gibt es dafür eine einfache Anleitung, wie man das auf dem Pi 400 hinbekommt? Meiner ist zwar noch nicht da, aber ich würde den Xemu dann auch gerne installieren.

Ich kann gerne eine hier eine Anleitung einstellen. Ist es okay, wenn ich sie auf englisch formuliere? Dann haben auch die im Mega65-Forum was davon, die kein Deutsch können.
Jepp, ist völlig O.K. in englisch.
Also für mich ... Wenn Du dann noch die Quellen für die ROMs und sonstige "Supportfiles" mit angibst.
Ich habe mir das Mega65 Teil mal schöngeguckt und so ein lauffähiger Emulator wäre ein weiterer Punkt, die Entscheidung Pro Mega 65 zu rücken.

The cheapest way to run on your already existing computer But OK, seriously, interesting (especially the performance numbers in the window title). Some years ago I tried to run (not the MEGA65 emulator of Xemu, since I haven't even started to write that back to then ...) I tried an Xemu emulator in Raspberry Pi (Enterprise-128 emulation) and it couldn't even hold real-time emulation. But I admit, Raspberry evolved a lot since then, and I haven't tested Xemu at all since then ... Though the latest Raspberry now I have, is only 3. Hmmm hmmm, anyway this "sexy" form factor (resembles a typical 8 bit design, ie case+kbd in one) is very attractive, I have to admit :-O
Awesome, we talked with LGB-Z many times about some Pi / ARM setup.
Well, yes, it's an old idea (like Commodore Pi tried to do) to implement a bare-metal emulation to achieve the max from the hardware also giving the impression "no underlaying OS" (in case of Rasp.pi, ususally Linux). But creating a bare-metal emulator means it's the OS as well, and that is, in its own, a whole featured project requires large amount of time (though nowadays we have kinda-ready-to-be-used solutions in source form to implement such things, but still, it's very far from being a trivial problem to solve).
Wo gibt es denn die Deutsche Version schon zu bestellen?

I agree 100% .
But I was talking about the ARM / Pi build of Xemu in top of Linux, no "magic" . Bare metal is crazy!
How to install Xemu on Raspberry Pi OS:
1. Open the shell with a click on the shell icon:
2. Install needed libraries with the following command in the shell:
sudo apt install git build-essential libsdl2-dev libgtk-3-dev libreadline-dev
If asked, type in your password (chosen during the setup of Raspberry Pi).
3. Copy the Xemu sourcecode from the github site with
git clone https://github.com/lgblgblgb/xemu
4. Change to xemu folder with
cd xemu
5. Build Xemu with
make
This takes a while ...
6. Load the needed roms with
make roms
7. Change to binary folder with
cd build/bin
8. Start Xemu(Mega65) with
./xmega65.native
9. This window appears, just press or click "OK":
10. The same here, just press or click "OK":
11. Here click the right option "Yes, ...":
12. Here press the "2" key:
13. Type "DELETE EVERYTHING" in capital letters (beware that a German keyboard "y" and "z" has changed places on the keyboard!) and press RETURN:
14. Press the "F10" key and select "Yes" for reseting the Xemu:
15. Click the right mouse button and select "SD-card" - "Update files on SD image":
16. Select the file "c65-system.rom" in the folder "pi/xemu/roms" and press "Open":
17. Press "OK"
18. That's it:
To start the Xemu again you just open the shell again and type:
xemu/build/bin/xmega65.native
Actually, in the context menu "(re)format sd-card" is the same effect, but surely you can do via MEGA65's utility as well, as described above.
Another thing: some can try to say "make deb" to create a debian (.deb) package, which can then even shared to the public and installed as package, without requiring the compilation process steps. But sure, for personal use, it does not make too much sense, to make a deb package and then install it. Also, I have to admit, I never tried creating deb package with Xemu's build-system on rasp-pi, so I am not sure if it works at all :-/
Wo gibt es denn die Deutsche Version schon zu bestellen?
Ich habe mein Set schon am 2. November hier bestellt. Im Moment scheint es aufgrund der großen Nachfrage wohl längere Lieferzeiten zu geben.
does it also run properly in fullscreen mode?
does it also run properly in fullscreen mode?
At the moment a only can test it with my small HDMI monitor with 1024x600 pixel resolution.
With it Xemu runs great in "fullscreen" mode:
A can't say anything about the speed with a fullscreen 4K monitor.
Did you try my xemu branch?
Not yet, but it's on my "want todo" list.
I'll report about it ...
Once I get a raspberry pi 400, I'll make an easy to install deb package anyway. Not because Snoopy's instructions are not great, but maybe not everybody keen to compile a software from source even if it's very well written by him.
Btw, a 8Mbyte memory version of raspberry pi 400 would be awesome (raspberry 4 itself has that, just not the 400 ...), maybe for light usual tasks I would switch to it as the "main computer" (just imagine, only about 6W of power it consumes - or something like that - under load, compare it to a usual PC ... OK, a modern PC is more fast/etc that's also true, but maybe not as much as the power consumption ratio would indicate ...).
