    Code Red Sim

    Code Red Sim

    A low-power ISA design and simulator for a 2010 IEEE competition

    This is a student project designed to compete in the 2010 IEEE Computer Society Student Competition: http://www.computer.org/portal/web/competition/2010competition The Code Red architecture is designed for extremely lower power environments, like distributed sensor networks. Included is a design of that architecture, a Java-based simulator, an implementation (without vector instructions) designed as a Logisim circuit (http://ozark.hendrix.edu/~burch/logisim/), and more. The name "Code Red" comes from our team name, the Red Team. Since the competition dictated a small team size, our professor split the class and gave each group a color. We liked the name "Code Red" and chose it to represent our team and school's color (UMass' official color is Maroon.) Only later did we realize that "Code Red" was the name of an unrelated computer worm from 2001.

    Coffee GB

    Coffee GB

    Gameboy emulator in Java 8

    Coffee GB is a Gameboy Color emulator written in Java 8. It's meant to be a development exercise. More info can be found in the blog post. First I implemented all the Gameboy CPU opcodes. It’s not exactly the Z80, but it’s pretty close. As a reference, I’ve used the GameBoy CPU Manual - later on I discovered that it has a few typos and is not specific enough for some of the operations. After implementing the opcodes and memory (modelled by an int[] array) I was eager to check whether it’s possible to run some code on it. I had neither the cartridge nor the GPU emulation yet, so even the simplest game wouldn’t be an option. However, when the original Gameboy starts, it executes a simple 256-bytes program, a kind of firmware displaying the Nintendo logo and self-testing the system. That was exactly the thing I was looking for - after just 3 days I had an application running the Gameboy code!

    EasyProtector

    EasyProtector

    Simple way to check root/virtual app/emulator/xposed framework

    EasyProtector, a simple way to check root/virtual app/emulator/xposed framework/tracer/debugger. Since it's all here, you are welcome to star/fork, even if you raise an issue, I hope this is a useful library (eliminate the initialization operation of the application, avoid more permission requirements, and load as lazy as possible) Mainly to fix a bunch of bugs, see the pictures in the image folder for the adaptation situation, Tencent Legu's old version of XposedCheck code has some code in copy SecurityCheckUtil, the new version can't see it anymore. After all, the simulator is a company-level product with limited personal capabilities. I hope everyone can mention more pr. Since 2018/6/13 integrated and launched your own project, the detection data of 11w+ suspected simulators have been collected by 10/24. If you need to do very detailed simulator identification in your business, you can add judgment conditions by yourself.
