Hey @vee,
Would love to see Doom running on a Tidbyt 
. The way Tidbyt works today is we render really tiny WebP images server side and send them back to the device over MQTT. We do that every 30 seconds or so depending on how fast you’ve configured your apps to cycle.
The way you could access that is through our API or through pixlet to push images to the device. We’re using an ESP32 microcontroller through, so there’s only so many pushes it can handle before it really starts to have a hard time.
If you really wanted to be a purist and get it running directly on the hardware - you could flash the ESP32 with your own firmware, though there are some pretty massive gotchas. We haven’t locked the bootloader by design - we believe that folks should be able to do whatever they want with devices they bought. However, we haven’t yet provided a way to get our firmware back onto your Tidbyt . This isn’t by design, we simply havnt had the time just yet 
. We also havn’t provided any form of base library or firmware so you don’t have to figure out our pinout. That’s something we’ve chatted about but havent come to a real conclusion on just yet.
Would love to hear your thoughts - let us know how we can best support you! Looking forward to seeing Doom running on your Tidbyt 
.
