A recreation of classic Doom inside Fortnite, built using Unreal Editor for Fortnite (UEFN). The demonstration combines Doom-style visuals with Fortnite’s building mechanics. Created as a learning exercise, the project recreates Doom’s appearance within Fortnite’s engine rather than running the original Doom engine.

Doom running on the circular display of a Fellow Espresso Series 1 espresso machine, demonstrated by Reddit user FullExtraction. The machine’s existing controls are used to play: the scroll wheel turns the player, the brew button moves forward, and the steam button fires. According to the creator, dying returns the machine to its regular firmware. A follow-up demonstration shows the whole machine and an updated display layout adapted to its circular screen.

MegaDoom is a wireframe demake of deathmatch Doom for the Uzebox open source 8 bit games console.  It features up to 4 players via Uzenet, two display modes, multiple levels and the ability to play with either a joypad or in "suoer mouse" mode using both a joypad and a SNES mouse. It features all the SFX from the PC original and music if you have at least 4 MB SPI RAM.

Although Kunos hasn't officially released modding support for UI apps yet, I started digging around to see if I can get something working myself, primarily because I really wanted some form of pedal telemetry while driving because that helps me a lot. After some excavations, I discovered that EVO's UI is primarly driven via JavaScript so once I knew that, I started trying to write my own pedal graph widget and when I added it to the hud.html of the game and packed it to kspkg and placed in the mods folder, it worked! And that's the pedal graph you see at the bottom-center of the screen (in the video it's running with a demo 'attract' option so you can see it working automatically because I'm not on my rig atm).

Some issues arose when I tried adding multiple ui apps because I discovered that only one mod can overwrite the hud.html and that's a no-go for multiple apps to run together. Because of this, I had to roll my own custom ui mod loader which acts as the single ui mod loaded in the game which then itself can handle multiple JavaScript apps running at the same time.

Anyways, once I wrote both the pedal graph app and then a dev console app, I decided to push further and try the de-facto standard: DOOM. I found a webassembly version of it at https://github.com/jacobenget/doom.wasm and tried running it directly as a ui app running with my custom ui mod loader but there I encountered an issue because the Coherent Labs Gameface Cohtml engine that's shipped with EVO doesn't support running webassembly (presdumably due to --noexpose_wasm).

To get around this webassembly issue, I used wasm2js to convert it to plain JavaScript and with that, DOOM was then running (without sound) inside EVO as a ui app running with the ui mod loader in conjunction with the two other custom ui apps.

Adding sound proved to be a bit more of an issue because I couldn't figure out a way of triggering custom sounds from the code of the ui apps. I tried with AudioContext but that was undefined so there's no support for Web Audio, and also tried <audio> but couldn't get that working either; <video> didn't work either because of no available demuxers so basically I couldn't play a wav or ogg or an mp3 like a browser would. After that I looked at stock game sounds in the game and I managed to play the inbuilt HUD sound effects (things like menu select and menu cancel and some other sfx) but the only I managed to get any form of custom sound working was by modifying the game's audio banks themselves, and I picked gui.bank for that (the livery editor was using most of the sfx here) and I patched it to replace the inbuilt sounds with the custom doom ones. Unfortunately I only found space for seven sounds inside that bank so I had to be very restrictive in the sound department. But once I patched the custom sounds in, it worked. And for the music I also had to use one of those previously aforementioned slots too to fit it in and had to settle with just one track.

All in all, it was a very fun experiment and there are still improvements to be had (for example sometimes I'm still getting hitches here and there as you can see from the video) but it works.

I will eventually be releasing the source code of everything I mentioned here (ACEUIModLoader, ACEPedalGraph, ACEDevConsole and ACEDOOM) on my github if anyone's interested in tinkering or creating their own ui apps.

A computer whose only instruction is a global regex substitution. The entire
machine is one 96.6 MB string: registers, RAM, the framebuffer and the DOOM
engine all live in it as plain text. A driver applies a fixed, ordered set of
544 find-and-replace rules in a loop; the first rule that matches fires once,
and that is one step. Nothing else computes. DOOM is compiled onto the machine
via doomgeneric and ELVM. One frame of E1M1 is 13,994,067 substitutions and
comes out byte-identical (SHA-256) to natively compiled DOOM.
