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. -

GoldHEN - PS4 Homebrew Enabler
PS4 Homebrew Enabler
GoldHEN is a homebrew enabler and payload designed for PlayStation 4 systems that enables the execution of unsigned code, modifications, and custom applications by leveraging kernel-level access. It functions as an enhancement layer built on top of exploited firmware environments, allowing users to unlock additional capabilities beyond what is normally permitted by the console. The project provides a wide range of system-level features, including debugging tools, cheat engines, and plugin support, making it popular within the console modification community. It integrates closely with the PS4 operating system to provide seamless functionality while maintaining system stability. GoldHEN also supports features such as FTP access and file system browsing, enabling users to manage internal data and install custom content. Its modular design allows developers to extend its capabilities through plugins and updates. -

NetherSX2
Continuation of NetherSX2 based on AetherSX2 4248
NetherSX2-patch is a community-driven continuation and enhancement of the NetherSX2 Android PlayStation 2 emulator, itself a modded fork of the open-source AetherSX2 project originally based on PCSX2. It focuses on providing a more complete and feature-rich experience by applying patches to the upstream emulator build and removing ad-related bloat, fixing notification issues, and exposing many internal settings so users have finer control over performance and compatibility on mobile devices. The project maintains an up-to-date GameDB (game compatibility database), improves controller support, and includes widescreen and no-interlace patches that make many games look and run better on modern screens. Developers also include additional fixes specific to AetherSX2 and NetherSX2 builds, along with tools to resign APKs to avoid Play Protect warnings, which makes installation smoother on Android hardware. -
