iHaiDeeZ/DolphinPS4 ? reverse-engineered prompt

Build me a PS4 homebrew app that lets me launch my own GameCube and Wii backups from the home screen and play them with a DualShock 4.

I want a nice couch friendly launcher with box art cover flow, and an option to switch to a PSP style XMB menu. It should remember my last game, let me sort and refresh the library, and pull missing cover art automatically when it starts. While playing, I want a quick pause menu from L3 plus R3 so I can save state, change settings, manage cheats, swap Wii Remote options, and quit back to the launcher.

Make settings work globally or per game, include memory card management, support up to four controllers, and let me customize themes, wallpapers, and menu sounds. It should also handle the PS4 hardware well, with Vulkan graphics, good performance, and a clean setup flow for my game files and saves. If you need anything unclear, look up the current docs online.
