The article reports 21 available apps, mostly emulators and games, and support for three devkits, controller input, up to four input devices, and audio streams. Firmware can be updated from microSD or GitHub, with automatic rollback if an update fails to start. Developers get an SDK and compatibility layers that allow some existing games to run with their original glue code. The project is described as more flexible than ESPBrookesia because apps reside on the card; its current focus is gaming. ### Source excerpt Gil Tal has developed the P4 Launcher, an open-source application platform designed to bring a PC-like experience to ESP32-P4 boards with an attached touchscreen display. The launcher boots directly into its interface, while applications (.papp files) are stored on a microSD card and loaded into PSRAM when launched. You can add, remove, and run applications without reflashing the firmware or rebooting the device by simply copying files to the microSD card.Gil says 21 PAPP (PSRAM APP) applications are available now, mostly emulators and games, including Neo Geo and Atari 2600 emulators, Doom, Quake, Duke Nukem 3D and OpenTyrian, plus Clock and Files. Like ESPBrookesia, the P4 Launcher user interface runs on ESP32-P4, but it's more flexible since it supports apps stored on the microSD card and targets mainly gaming for now. The launcher currently works on the Guition ESP32-P4 4.3″ (800x480), the Guition JC1060P470C 7″ (1024x600), and the smaller M5Stack [...] The post P4 Launcher offers a PC-like and retro gaming experience on ESP32-P4 boards appeared first on CNX Software - Embedded Systems News. ## ICYMI Python on Microcontrollers Newsletter: Adafruit Metro P4 Hydra, Possible New Raspberry Pi Boards, JIT Gone and More! DevFeed: [ICYMI Python on Microcontrollers Newsletter: Adafruit Metro P4 Hydra, Possible New Raspberry Pi Boards, JIT Gone and More!]() Original publisher: [Read original article]() Author: Anne Barela Published: 2026-11-03T14:35:06Z Content type: news Language: en Sources: [Adafruit Industries]() Topics: [Python](), [CircuitPython](), [MicroPython](), [Raspberry Pi](), [Raspberry Pi RP2350](), [Learning](), [Tool](), [Tutorial](), [3D](), [ESP32-C3](), [AI Chat](), [pip]() Tags: [adafruit](), [adafruit-daily](), [ai](), [circuitpython](), [hydra](), [icymi](), [jit](), [metro](), [microcontrollers](), [micropython](), [newsletter](), [p4](), [pi](), [programming](), [publications](), [python](), [python-on-microcontrollers](), [raspberry-pi](), [sbc]() ### AI overview This week's Python-on-hardware roundup highlights faster CircuitPython graphics, new hardware, and changes in Python tooling. Adafruit's Metro ESP32-P4 Hydra combines an ESP32-P4 and ESP32-C6 on an Arduino UNO-shaped board, with display and camera connectors, USB host, microSD, and CircuitPython 11.0.0-alpha.2 support. Linux device-tree files suggest possible Raspberry Pi Zero 3 W and Pi 4 Model A boards, but Raspberry Pi has not announced them and key specifications remain unknown. CPython's experimental JIT is being removed from the main project after its team missed a support plan deadline; the Steering Council cited small gains concentrated in long-running tight loops, while outside development may continue. Expedited Python 3.11-3.15 security releases address certificate and library issues. In one bitmap-display benchmark, CircuitPython 11.0.0-alpha.2 reduced draw times versus 10.3.1 on both a Pico and Pico 2 W. Other projects include shared LVGL bindings across CPython, MicroPython, and CircuitPython, and a MicroPython Game Boy emulator whose Viper-compiled code meets a 60 Hz frame budget on a GitHub badge. ### Source excerpt If you missed this week's Python on Microcontrollers Newsletter, here is the ICYMI (in case you missed it) version.
