NetherSX2 Classic
Continuation of NetherSX2 based on AetherSX2 3668
NetherSX2-classic is a companion and variant of NetherSX2 that targets a specific older base version of the AetherSX2 emulator (based on the 3668 branch), applying similar custom patches to provide a stable and performant PS2 emulation environment on Android devices. The project stitches in anti-tampering modifications, RetroAchievements notification fixes, and controller and GameDB updates while maintaining the legacy behavior of the classic build for compatibility with titles that might perform better on the older codebase. Because this classic branch starts from a slightly different upstream version than NetherSX2-patch, users often choose it for performance reasons on lower-power devices or for games with known regressions in newer builds. As with the patch variant, the repository includes configuration changes, fixes for widescreen and deinterlacing behavior, and updated game and controller support developed by the community. -

AndroidNativeEmu
Allows you to partly emulate an Android native library
AndroidNativeEmu is a Python-based framework designed to partially emulate Android native libraries, enabling developers and researchers to analyze and execute native code outside of a full Android environment. Instead of emulating an entire operating system, it focuses specifically on the native layer, allowing for targeted testing and reverse engineering of shared libraries (.so files). This makes it particularly useful in security research, malware analysis, and debugging of Android applications. The framework provides tools for loading binaries, simulating system calls, and interacting with native functions in a controlled environment. By abstracting away the complexity of full device emulation, it allows faster iteration and more focused analysis of specific components. It also integrates well with Python tooling, making it accessible and extensible for custom workflows. -

GramAddict
Completely free and open-source human-like Instagram bot
GramAddict is a fully open-source Instagram automation bot designed to simulate human-like interaction on Android devices using UI automation rather than direct API calls. It operates through ADB and UIAutomator2, meaning it interacts with the Instagram app as if it were a real user, reducing the risk of detection compared to API-based bots. The tool can automate a wide range of actions such as liking posts, following users, sending messages, and browsing content, all while introducing randomized delays and behaviors to mimic human activity. It supports both physical devices and emulators, making it flexible for different deployment environments. The project also includes advanced filtering and targeting capabilities, allowing users to define specific audiences based on hashtags, locations, or user attributes. Additionally, it provides reporting features via Telegram, giving users real-time feedback on bot performance. -
