Developer here :)

Just saw this and love how I got the 100th or so "Does it run DOOM?". Even now officially an issue on GitHub. Does that mean I now have to deliver?

I know it was intended as a joke but still..

How optimal is the PCB density? Do you think there is significant room for improvement to have a smaller PCB and larger screen and/or battery?
The PCB can be way smaller, but finding a flexible screen is the issue, there is a 2.9 inch one almost twice as big but the battery would suffer :/
?? add relevant wifi/port to connect to a projector/projection glasses / laser projector[0]

3 old micro ibm hard drives combined into rgb color space / diy laser image projector[1] might be able provide a bigger picture without exceeding DIY credit card size. kinda depends on laser size.

Ummm... a smartphone internal projector module more compact than diy stack of ibm microdrives / laser.[2]

Not worrying about size: esp32 laser dac : https://www.youtube.com/watch?v=9YASnlB_t_U

Yes ;)
So... it's not DOOM-complete?

Teenage Alan T. would be so disappointed... :D

Well, using something related/similar to turing-complete correspondence:

----

If it can fetch/display files from the internet, yes, it can run doom[5]. Or make use of curl, curl-doom[18]

-----

stripped down doom can run in 4MB (doom on a smart toothbrush[7]). ESP32 has support for up to 4MB external PSRAM[1]. ESP32 port of doom[2]. lcd screen might provide for faster refresh / less blury images under magnifying glass.

Alternatively, adding an expansion port to be able to use 'doomchip' might make it easier hide game play while at work[8] / stay awake between screen frame refreshes. (and/or simulateously play tetris & 1d pacman; add Badgey functionality[19] )

But should one go with micropython[3], reflectionsOS[4] or not waste space and use a 2 stage 512k bootloader for dns.doom[5]?

contikiOS[6] for dns.doom[5] might be the correct fit without needing to add 4mb psram / doomchip expansion port(s).

-----

Misc doomchip information:

   doomchip non-tech article(2020)[11].

   doomchip developer comments[12]. Should be able to get at least 2fps!

   doomchip better expanded upon in a 'heads up, 7up' thread -> slice[9]/doomchip[10].
----

Surprised there's no dns doom.wad / I.D.Software Application (IDSA) rfc "Spit.wad: A DNS string encoding using Unicode for doom.wad graphics" version of rfc3492: "Punycode: A bootstring encoding of Unicode for Internationalizaed Domain Names in Appliations" (IDNA) [13]

(IDSA) rfc might permit formally unifying things like unicode-line-stacker[14], stacked diacretics generator[15], unicodeart[16] and "awesome symbols and characters in a bash prompt"[17].
