    NetherSX2 Classic

    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. ...

    Ruffle

    Ruffle

    A Flash Player emulator written in Rust

    Ruffle is an open-source emulator for Adobe Flash Player, written primarily in Rust, and targeted at both desktop applications and web browsers via WebAssembly. Its goal is to enable legacy Flash content—animations, games, interactive media—to continue running safely and reliably after official Flash support was discontinued. On the web side, Ruffle is embedded into pages or installed as a browser extension; in the desktop version, it can open .swf files directly or embed them in applications. Because it’s built with memory safety in mind, Ruffle helps avoid many of the security vulnerabilities that plagued classic Flash (buffer overflows, use-after-free, etc.). ...
