So the new generation of semi-affordable thermal imaging cameras (InfiRay C200, Vevor SC240, TopDon, etc.) apparently contain a SoC from HiSilicon and run Linux.
Only appropriate to get them to run DOOM then:

The internal framebuffer is actually YVU420SP, rather unusual color format (but I guess it makes sense for a surveillance camera SoC).

Another very important mod of course is to replace the vendor logo. It‘s actually stored as a JPEG at a fixed offset on the internal eMMC flash and u-boot just reads 64kBytes from that location and feeds it into a hardware JPEG decoder engine.
The SDK sourcecode for this is abhorrent, as you‘d expect and it only works with baseline (not progressive) JPEGs. Oh well 😸
