| Component | Purpose | |-----------|---------| | libretro_android.so | RetroArch or AetherSX2 core | | game.iso or rom.wua | Dumped PS3/Wii U game data (illegal if copyrighted) | | touch_controls.cfg | Overlay mapping for touch inputs | | assets/fake_obb/ | Decoy files to mimic official game size (often 1-2GB) |
