what is at-cardwars-vita fr?

AT-CardWars-Vita is a project that ports the mobile game Card Wars: Adventure Time to run natively on a PlayStation Vita handheld console. The original game was released for iOS and Android but shut down along with the servers it needed to run, so this project takes an existing decompiled PC version of the game and gets it working on Vita hardware instead. It was built using Unity 2017.4 targeting the Vita's PSP2 platform. The README notes that the Vita needs to be overclocked, meaning its CPU and GPU are pushed to run faster than their default speed, in order to keep the game running at a stable frame rate. Installation is not a simple download and play process. The repository does not include the game files directly, since those belong to the original commercial game. Instead, it provides a patch file that must be applied to a copy of the original Card Wars iOS app that the user already owns, using a separate patching tool called xdelta3. The instructions walk through installing a stub app on the Vita, downloading xdelta3, running a command to apply the patch to the original game files, and then copying the resulting files onto the Vita in the right folder. A video demo of the installation process is linked for anyone who wants to follow along visually. Save files are stored separately from the main game data, so they are not lost if the game is reinstalled or updated. The README credits another community member for providing the LiveArea menu artwork used in the port. This project is aimed at people who already own the original Card Wars game and want to keep playing it on a PS Vita after the official servers went offline.
