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. -

dracxterm
An Android terminal that runs Linux without root, with an AI assistant
dracxterm puts a real Linux workstation on your Android phone. Open it and a shell is ready to type in. When you want more, the app installs Debian 13 or Kali Linux inside its own storage, and you work the way you would on a laptop. The phone does not need root, there is no account to create, and no companion app to install. A real Linux, inside the app Pick a distro and the app downloads and sets it up for you. Once it is in place you get apt, dpkg, sudo, su and fakeroot, so you can install packages, build software, and run tools like git, ssh, curl, python and nmap the way you would on a desktop. VHDP, a rootless engine built into the app, runs the Linux session. On a phone that cannot run it, the app falls back to an older engine on its own, so the terminal still works. Decline the distro entirely and you still get a working BusyBox shell. claw, an assistant that lives in your terminal What makes dracxterm more than a terminal is claw.
