Title: Dynamic Repatching Techniques in Vita3K: Enhancing Compatibility and Performance for PlayStation Vita Emulation

Currently, modding a game in Vita3K is cumbersome. Most mods require users to decrypt the game, replace assets (textures, text files, audio), and then repackage the title into a loadable format. This process risks breaking the game, wastes storage space, and discourages experimentation. On a real Vita, repatch works by creating a separate folder hierarchy ( ux0:repatch/[TITLEID]/ ) that overrides original files in memory. The emulator loads the original decrypted data but checks the repatch directory first for any modified files. This elegant method keeps the base game intact while allowing mods to be swapped, updated, or removed instantly.
