emulation

I'm looking to build a VM into a game and was wondering if anyone knew of any really simple VM's (I was thinking RISC/PIC was close to what I wanted) that are usually used for embedded projects such as controlling robots, motors, sensors, etc. My main concern is having to write a compiler/assembler if I roll my own. I'd be nice to use the tools that are already out there or in its simplest form just a C compiler that can compile for it :-p. I really don't want to re-invent the wheel here but I also need thousands of these running around a virtual world so they have to be as simple and as fast

I am currently making an upgrade of an existing app that's already on the Google App store (aka Google Play). I want to test that the data conversions go smoothly when customers upgrade. I have an AVD with the old version of the app installed. The usual thing would be to run the new version on this app and see if it works. But the problem is that after doing this, that particular AVD is no longer mimicking that old state. I'd like to make copies of this AVD/Emulator (yeah, the whole thing!) so that I can make repeated tests. This seems like something that would happen often, but I can't find

I have issues with the build in qemu emulator in Android Studio. There are some other Android emulators out there. How to configure Android Studio to use a different emulator? I use leapdroid emulator http://www.leapdroid.com to run apps and games. Leapdroid is compatible with Android adb, i.e., using the same port numbers starting with 5555, so there is really nothing special to do, pretty much same as what you do with the built-in Android emulator. If you run "adb devices", you will see a device named as "emulator-5554". Here are the steps: Launch Leapdroid vm, which contains android 4.4.4

I am used to that Python allows some neat tricks to delegate functionality to other objects. One example is delegation to contained objects. But it seams, that I don't have luck, when I want to delegate __contains __: class A(object): def __init__(self): self.mydict = {} self.__contains__ = self.mydict.__contains__ a = A() 1 in a I get: Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: argument of type 'A' is not iterable What I am making wrong? When I call a.__contains __(1), everything goes smooth. I even tried to define an __iter __ method in A to make A more

Emulator started, but not booting further "android" flashing text.

Was working fine with KVM end virtualization, but suddenly stopped after updating to emulator to 26.1.2-4077558. Update Thanks to albodelu for information about update to 26.1.3.
