MAME4droid
MAME Android Emulator.
MAME4droid (0.139u1) is developed by David Valdeita (Seleuco), port of MAME 0.139u1 emulator by Nicola Salmoria and TEAM. MAME4droid (0.139u1) emulates arcade games supported by original MAME 0.139u1. This MAME4droid version is targeted to Dual-Core devices, because it is based on a high specs 2010 PC MAME build. Anyway don't expect arcade games of the 90 to work at full speed. With some games that are really bad optimized (like outrun or mk series) you will need at least a 1.5 ghz dual-core device (Cortex A15). This is related to MAME build used, since it is targeted to high specs PC's as i said before. This version emulates over 8000 different romsets. Please, try to understand that that with that amount of games, some will run better than others and some might not even run with MAME4droid. Please, don't email me asking for a specific game to run.

Simplify
Android virtual machine and deobfuscator
Simplify virtually executes an app to understand its behavior and then tries to optimize the code so that it behaves identically but is easier for a human to understand. Each optimization type is simple and generic, so it doesn't matter what specific type of obfuscation is used. Provides a virtual machine sandbox for executing Dalvik methods. After executing a method, it returns a graph containing all possible register and class values for every execution path. It works even if some values are unknown, such as file and network I/O. For example, any if or switch conditional with an unknown value results in both branches being taken. Analyzes the execution graphs from smalivm and applies optimizations such as constant propagation, dead code removal, unreflection, and some peephole optimizations. These are fairly simple, but when applied together repeatedly, they'll decrypt strings, remove reflection, and greatly simplify code. It does not rename methods and classes. -

J2ME-Loader
A J2ME emulator for Android
J2ME-Loader is a J2ME emulator for Android. It supports most 2D and 3D games (including Mascot Capsule 3D ones). Emulator has a virtual keyboard, individual settings for each application, scaling support. This project is a fork of J2meLoader. Enabling filtering in some cases can greatly reduce performance. Disable this option if the game is too slow. Image flickering issues can be fixed by enabling the "Immediate processing mode" option. -

Muon SSH Terminal/SFTP client
Graphical SFTP client and terminal emulator with helpful utilities
Easy and fun way to work with remote servers over SSH. This project is being renamed as previous name "Snowflake" is confusing since there is already a popular product with the same name. Muon is a graphical SSH client. It has an enhanced SFTP file browser, SSH terminal emulator, remote resource/process manager, server disk space analyzer, remote text editor, huge remote log viewer, and lots of other helpful tools, which makes it easy to work with remote servers. Muon provides functionality similar to web-based control panels but, it works over SSH from the local computer, hence no installation is required on the server. It runs on Linux and Windows. Muon has been tested with several Linux and UNIX servers, like Ubuntu server, CentOS, RHEL, OpenSUSE, FreeBSD, OpenBSD, NetBSD, and HP-UX. The application is targeted mainly towards web/backend developers who often deploy/debug their code on remote servers and not overly fond of complex terminal-based commands. -

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! -
