RetroESP32-P4 is a retro gaming and application platform based on the powerful ESP32-P4.

Built from my recent revival of the original RetroESP32, this project brings modern UI, HDMI support, touchscreen support, 15 emulators, and native apps running from SRAM.

• NES
• Game Boy
• Game Boy Color
• Game Gear
• Sega Master System
• ColecoVision
• Sinclair ZX
• Atari Lynx
• Atari 7800
• Atari 2600 (Supports paddle for breakout, Kaboom and the alike in the console mode)
• Atari 800XL / 5200 (Supports paddle for breakout, Kaboom and and the alike in the console mode)
• PC Engine
• SNES
• The mighty NeoGeo!!! Fully operational!
• Sega Genesis / Mega Drive

• Most systems run at 60 FPS (without frame skips!)
• SNES / Genesis run 60 FPS (with around 10 frames drops per second - game play is totaly smooth)
• NeoGeo 60 FPS (with around 0-20 frames drops per second - game play is totaly smooth)

All emulators support Save / Load states (some from within the games)

Plug any USB controller and automatic button mapping starts on first use (For the HDMI version you need L2 and R2 for Menu and Volume buttons in SNES and Genesis, a PS3 controller is best, cheap clones are available on AliExpress)

• 480x800 touchscreen (https://www.guition.com/esp32p4-display-module/esp32p4-display)

• Full handheld mode

• Can be purchased on AliExpress or from Guition site:

  

• Guition ESP32-P4 board (https://www.guition.com/esp32p4-display-module/esp32p4-display-module)

• Olimex LT8912 DSI(MIPI)-to-HDMI bridge (https://www.olimex.com/Products/IoT/ESP32-P4/MIPI-HDMI/open-source-hardware) (Be very careful to use the correct DSI flat cable, better to buy it from Olimex - https://www.olimex.com/Products/IoT/ESP32-P4/FPC-15-1.0-150/)

  

  

  

Apps load from SD card and execute directly from SRAM.

Included:

• Doom
• Quake
• Duke3D
• OpenTyrian
• Example demo template

• Modern launcher
• Fast navigation
• Search for ROM files
• Better file browsing

1. Format SD card to FAT32
2. Copy contents of /SDCARD
3. Flash firmware to address 0 (RetroESP32_P4_v1.bin or RetroESP32_P4_HDMI_v1.bin) (https://espressif.github.io/esptool-js/)
4. Insert SD card
5. Connect controller or plug into the console frame
6. For NeoGeo games you will need to run the python script to generate the cache files (script is at the SD card folder)
7. Enjoy

• Firmware binaries
• Source code
• SD card files
• Apps
• Templates
• Console board production file and schematic
• STL files

• More emulators
• Better performance
• More apps
• Improved UI
• WiFi features
• BLE controllers

This is only Version 1.

RetroESP32-P4 is not just another emulator project — it's a demonstration of how far modern microcontrollers can go when optimized correctly.
