The Pocket 3+ is an Android device, so there is no Linux "custom firmware" like bare-metal handhelds have. Customizing it means installing an emulation front-end on top of stock Android 11 to make it feel like a console. The popular choices are ES-DE and Daijisho, both of which sit over Android and launch standalone emulators or RetroArch. Install the front-end from Google Play (or sideload its APK), keep your ROMs in tidy per-system folders on the microSD, point each platform at its folder, choose an emulator per system, and scrape artwork. You can set the front-end as the default Home app so it opens at boot. None of this requires root, unlocking the bootloader, or replacing the official firmware.

FAQ

Can I install Linux or a CFW like on a non-Android handheld?
No. The Pocket 3+ is an Android handheld. Instead of CFW you install a front-end (ES-DE or Daijisho) over stock Android, which needs no root or bootloader unlock.
Which front-end should I pick, ES-DE or Daijisho?
Daijisho is quicker to set up; ES-DE is more configurable and very console-like once done. Both run RetroArch and standalone emulators; try one and switch later if you like.
