Emulating the pi in Windows

Recently I have been trying to emulate the raspberry pi in windows for various reasons. I have been trying to use QEMU because it was recommended to me by lots of people. I keep getting an error which I cant seem to overcome despite lots of things I have been trying. the error does not say it is an error, but it gets stuck on 'Freeing init memory: 132K' for ever until I force close QEMU. It seemed to work in an older version of raspbian (can't remember which one), but now on the 2014-01-07 distro it just gets stuck. Please if anyone has any ideas I would much appreciate them.

Here's the qemu.bat file I created for my system.
Code: Select all
"C:\Users\Dougie\Qemu\qemu-system-armw" -kernel kernel-qemu.new ^
-cpu arm1176 -m 256 -M versatilepb -no-reboot -serial stdio ^
-append "root=/dev/sda2 panic=1 rootfstype=ext4 rw" ^
-hda c:\Users\Dougie\Qemu\Raspbbian-Freddy.resized.img ^
-net nic -net tap,ifname=OpenVPN
you MUST use "-m 256" or qemu won't start.
I'm using the tap interface (installed with OpenVPN) to get connectivity to my qemu system.

Have you managed to get this working with other distro's besides Raspian?

No, because it needs a special kernel built for Qemu and I don't know how to do that.

You can run the latest piCore-5.3 in QEMU, see article

I have previously gotten Raspian working fine. But I am doing some work under ArchLinux (and Arkos), and after some research, there was mention that Arch needed some additional changes to the kernel to work. Using the script located here (
https://github.com/johnlane/rpi-utils), I created the kernel as supposed to. But as shown on the attached image, it kernel panics...

The more frustrating thing is, using the same files under Ubuntu - works happily - just not Windows.
