On the Pocket 4 Pro there is no Linux-style custom firmware like on Anbernic Linux units; it runs Android, so customization means swapping the front-end over stock Android. Most users install RetroArch (the stable build, not the Play Store one) for cores up to PS1, add standalone emulators for heavier systems, then layer a console-like front-end such as ES-DE, Daijisho, or Beacon. These organize your library, scrape artwork, and launch games into the right emulator. The stock Retroid launcher and the AOSP launcher both remain available, and you can set any of them as the default home app.
