A measure of compatibility and sheer hobbyist will: The classic shooter Doom even runs on the Adafruit QT Py mini board.

But does it make Doom run? The winged challenge to all computer tinkerers and resourceful coders has borne amazing fruit, like Doom inside Minecraft or even the latest Doom Eternal on a smart fridge.

Now the Adafruit QT Py mini-board shows that with a little tinkering and a 240×240 pixel screen, even the classic shooter runs without a hitch. The build, which has been specially configured for gaming, features a control pad and six action buttons, allowing the simple controls of Doom to be operated.

On the tiny device, Doom can be seen surprisingly clearly and played smoothly. Take a look for yourself:

Doom was made executable on the QT Py with the help of the emulator Retro-Go. To do this, the tool first had to be ported for the mini board, as the hobbyists explain on the website of (Adafruit). The build should not only be able to play Doom smoothly, but also Doom. The device has the following specs:

  • ESP32 Pico v3 02, Dual Tensilica 240 MHz core with 2 MB PSRAM, 8 MB Flash
  • 240×240 1.3 inch TFT IPS
  • microSD card
  • AW9523 GPIO expander for 10 buttons, constant current backlight, headphone mute, card detection

The source code of Doom is open source – one of the reasons why the classic shooter is so often used to demonstrate compatibility. Well, it’s also almost 30 years old and requires correspondingly few hardware resources. And of course Doom is a classic.

On the other hand, the graphics benchmark for high-performance PCs has been called But does it make Crysis work? for 15 years. PC gamers will have to ask themselves this question again, because surprisingly Crytek announced the long thought impossible Crysis 4 these days:
