I got Teamspeak 3 running using qemu running a x86 Debian squeeze. There is some room for improvement for sure, but for now that's what worked for me. I hope I didn't forget something.
First of all thanks to Dietmar and meigrafd of the raspberry pi forum. Without their work I wouldn't have succeeded.
We need some software apt-get ...
you need to recompile a kernel in order to do that.
create your image with no more than 224 colors, and 80x80px in size.
Save the image as png, and run the following (provided you have netpbm installed and kernel source in /usr/src/linux):
$ pngtopnm logo.png | ppmquant -fs 223 | pnmtoplainpnm > logo_linux_clut224.ppm
$ cp logo_linux_clut224.ppm /...
To set up an emulated environment of the Raspberry Pi software on OSX one will need:
A Cross-Compiling Tool for the CPU architecture of RPi. ( eg. ARM
EABI Toolchain )
The RPi Kernel.
The RPi root filesystem.
The Emulator (QEMU).
The Cross-Compiling Tool for the ARM architecture.
Assuming one already have the latest Xcode and command line tools from Apple ...
Yes, I have built a kernel and ported Docker 1.0 to the Raspbian OS: Linux raspberrypi 3.10.37+ #1 PREEMPT Sat Apr 19 13:28:05 UTC 2014 armv6l GNU/Linux
I have shared my outputs on GitHub to save others the pain. As is usual I have provided this 'as-is' with no warranty ;-)
You can find the kernel & docker tar file here:
You definitely cannot upgrade the ram. It is mounted to the CPU and is not user upgradeable like a desktop computer is. You can't physically swap out the CPU either, what you may be able to do is overclock the CPU but that may already have been done. You can set the clock speed using the following command:
As for clustering, the program ...
As MDMarra suggested, you can skip this assignment by holding any button. If you do have a dedicated button like the Xbox button or PS button on your controller, you can assign it to make some of the emulator shortcuts use it.
Here are the shortcuts I've seen so far:
Hotkey+Start = exit emulator
Hotkey+Right shoulder = save state
Hotkey+Left shoulder = ...
QEMU supports a platform called "raspi2" directly since version 2.6 at least. I believe work is ongoing to refine
the support for all Pi models including the RPi3. Currently , only older Raspbian images and Windows IoT Core are partially supported.
It's not really possible to simply upgrade RAM or CPU. Both are one solid package soldered onto the board.
Cluster computing also won't solve this - it simply does not work like you'd hope it would. Bringing more than one computer to work at the same task is complex to say the least and the emulation software you run your games with can't profit from the ...
You could use qemu (http://wiki.qemu.org/Main_Page) to emulate a Raspberry Pi on your computer, and feed your SD card as the boot device in the command line options of qemu.
QEMU can be used on Windows/Linux/Mac.

There is a few things you can do.
Put a fan/heatsink on your Raspberry Pi.
This would prevent the CPU from throttling if it gets too hot, insuring stable performance and helping with 2.
Overclock your CPU
Just making it run faster should improve your performances, but you really want to look into 1. first.
Tweak the RAM allocation towards GPU or CPU, ...
You can also use HypriotOS, which provides the latest Docker and Linux kernel for Raspberry Pi. Just flash the image and see Docker up and running!
(disclosure: I am a team member of Hypriot)
You can hold down any key to skip it if you don’t have a spare button.
If you had a dedicated hot key button, it would take the place of “select” for activating the emulator shortcuts while in a game (such an quitting back to EmulationStation or opening the retroarch menu).
Not impossible, but here are the obstacles to overcome:
First, the SD card knows nothing about FAT, ext4fs, or any other file system. What it does is accept commands from the host interface and either store the data given to it, or retrieve data and send them back to the host. The filesystem interface is implemented at a higher layer. Whatever you create ...
I really hate to be a ball buster here, but at what point did you associate Raspberry Pis and "high performance NAS." Although it'd be a cool project like this, Raspberry Pis just aren't that powerful. They're low cost for fully functioning computer, but they are by no means cheap for their computing power.
I would recommend a device more adequately ...
XBMC supports starting external applications like MAME arcade emulator from it. MAME on Pi:
As @dastaan said, the kernel version needs to match the img file. I was trying to use a 4.1 kernel version image file with a 3.18 kernel.
Now that I am using the proper image, it works.
Edit: Getting this to work is pretty straightforward: Grab the image from https://github.com/dhruvvyas90/qemu-rpi-kernel/, then download the corresponding Raspian ...
You would have to reprogram the legacy games entirely. Think about it this way: cluster computing with 2 Raspis would make sense only when you can split the task up between 2 computers. In addition, the processor is faster than the USB. There is little practical point for clustering.
My advice would be to overclock the Raspi (would try first) or change in-...
Get yourself a copy of PINN that will let you pick any one of a multitude of operating systems to multi-boot on your RPi.
You should be able to fit LibreElec, OSMC, Retropie and Raspbian on a 32GB or 64GB SDcard.
The append line adds extra options to the kernel command line in UNIX derivatives. You can add many extra options such as
root device (/dev/sda2 in your example)
debugging options such as 'quiet'
hdd emaulation (ide-scsi)
boot type (single, rescue etc.)
You can find which options you can pass to append line in QEMU kernel options ...
If you use Raspbian:
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install docker.io docker
Docker is now in the default repository,
Update: unfortunately this version is quite old, so pulling in images from Docker Hub won't work at the moment.
There is a ready to run paid option that runs over QEMU: https://snorfi.us/raspiemu/
If you don't want to pay for it you can also download the alpha version in https://sourceforge.net/projects/raspberrypiemulator/
to emulate function keys F1 - F12 on a standard US keyboard (equaling your Logitech K700 design) I suggest to do the following:
first create some file e.g. '/etc/X11/Xmodmap' with these contents:
keycode 66 = Mode_switch
keycode 10 = 1 exclam F1
keycode 11 = 2 at F2
keycode 12 = 3 numbersign F3
keycode 13 = 4 dollar F4
keycode 14 = 5 percent F5
keycode 15 ...
I tried various tutorials, but the results were always too slow to be useful. (took 20 mins to boot, took 1 min to register a mouse click, 10 minutes to open Windows Explorer, etc)
Then I discovered PINN has a pre-built image that emulates Windows 98 at a usable speed. (boots in less than 3 min, mouse click register in 5 seconds, 2 min to open Windows ...
Docker supports ARMv6/v7 and even ARM64 (v8?), so you can run it on your Raspberry Pis.
Follow the official instructions from Docker here: https://docs.docker.com/engine/installation/linux/docker-ce/debian/
If you have Raspbian Jessie or Stretch (check the above documentation for others), this would be:
$ sudo apt-get install apt-transport-https ca-...
If you were looking to go mobile, SSH or VNC are the best options for working without a separate monitor. Both of these require the Mac and the Pi to be connected to the same WIFI/Ethernet network, however I have read somewhere you can directly attach them with an Ethernet cable. Something worth looking up.
SSH is the best option if you are only using the ...
Even if a game or emulator could make use of multiple computation units -- which is very, very unlikely, especially in older games designed for single-core platforms -- communication cost would likely be prohibitive for most gaming purposes.
Every piece of information would have to go through the whole TCP/IP-Ethernet stack (unless you use special hardware ...
