24 alternatives to Onramp Can Compile Doom
Onramp Can Compile Doom is a software tool that enables compilation of the classic video game Doom. Created for developers and retro gaming enthusiasts, it streamlines the process of building Doom from source code. The… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

I got DOOM running in KiCad by rendering it with PCB traces and footprints instead of pixels. Walls are rendered as PCB_TRACK traces, and entities (enemies, items, player) are actual component footprints - SOT-23 for small items, SOIC-8 for decorations, QFP-64 for enemies and the player. How I did it: Started by patching DOOM's source code to extract vector data directly from the engine. Instead of trying to render 64,000 pixels (which would be impossibly slow), I grab the geometry DOOM already calculates internally - the drawsegs[] array for walls and vissprites[] for entities. Added a…

I made a Doom source port that runs within a PDF file. I was inspired by the recent HN post about Tetris in a PDF (https://news.ycombinator.com/item?id=42645218) and I wondered if I could get Doom to run using a similar method. It turns out that old versions of Emscripten can compile C to asm.js code that will happily run inside the limited JS runtime of the PDF engine. I used the doomgeneric (https://github.com/ozkl/doomgeneric) fork of the original Doom source, as that made writing the IO fairly easy. All I had to do was implement a framebuffer and…

I sometimes pick up random projects just because I can, this was one of those times. I made it as a week long project a while back this year but never shared here, so thought to go for it haha. I created a game inspired by Doom and the backrooms called The Backdooms under 2.4kb in minified html. (for reference, this entire post would be around 1.8kB haha) I had to use a not popular way of using GZip with Zlib headers (had to write my own script for compressing it, also in the repo) to eventually convert it a size 40 QR code that works right in your browser using Decompressionstream API. This…

Hi HN, I’ve been working on Gore – a port of the classic Doom engine written in pure Go, based on a ccgo C-to-Go translation of Doom Generic. It loads original WAD files, uses a software renderer (no SDL or CGO, or Go dependencies outside the standard library). Still has a bit of unsafe code that I'm trying to get rid of, and various other caveats. In the examples is a terminal-based renderer, which is entertaining, even though it's very hard to play with terminal-style input/output. The goal is a clean, cross-platform, Go-native take on the Doom engine – fun to hack on, easy to read,…

TrueType fonts have a hinting VM that grid-fits glyphs. It has a stack, storage area, conditionals, function calls, and it turns out it's Turing-complete. So I built a raycasting engine in the hinting bytecode. The glyph "A" in the font has 16 vertical bar contours. The hinting program reads player coordinates from font variation axes via GETVARIATION, does DDA ray marching against a tile map in the storage area, and repositions bar heights with SCFS. It ends up looking like a crude Wolfenstein-style view. Small visuzlization:…

Demo: https://www.youtube.com/watch?v=f5uygzEmdLw Hi HN, I built a RISC-V emulator that implements the RV32IM instruction set and a minimal syscall interface to run DOOM. A few weeks ago, I got my first output with a simple hello world assembly program. Since then I have been working tirelessly to get DOOM to run. I needed to figure out how to run C programs first, and came across newlib, which allows the underlying environment to implement the syscall stubs one by one until the programs run. I have also added ELF loading, but currently only a single `PT_LOAD` segment is…

Hi there! I've been on-and-off working on TacOS for a few months, which follows some UNIX-derived concepts (exec/fork, unix-style VFS, etc) and is now able to run a port of Doom, with a fairly small amount of modifications, using my from-scratch libc. The performance is actually decent compared to what I expected. Very interested to hear your thoughts. Thank you!

Wadzilla is currently a PoC. Although in theory it “works”, it does not create an entertaining experience as a game, although to me it is quite fun just too see it output ZIL for all of the rooms in a DOOM WAD, with all of the objects in all of their correct locations by their plain English names, along with the 8-character names for the textures of the walls, floors, and ceilings in their relative positions in the room. Part of that enjoyment of course comes from knowing what it entails just to get that far, so the amount of entertainment you derive from that may be far less. In fact, I…

This Ghidra extension unrelocates machine code through analysis and then synthesizes a working object file from a listing selection. It effectively turns computer programs into Lego bricks, to be torn down into pieces and reused into something new. It supports the COFF and ELF object file formats, for the x86 and MIPS architectures. It has been successfully used on Linux, Windows and PlayStation executables. One user report is on a commercial video game from 2009 with a ~7 MiB Windows executable written in C++: it was delinked without its C runtime library and then relinked into a new…

I've been recently working on porting standard C library functions to work on the GPU https://libc.llvm.org/gpu/. A colleague of mine suggested using it to run DOOM, so that's what I did. It runs on both AMD and NVIDIA GPUs and it is completely playable. This works by targeting C code directly for the GPU via cross-compilation in clang, looks something like this https://godbolt.org/z/hh44a6vKr. The LLVM C library will provide the headers, C library functions, and the kernel that calls the main function, so we only need to compile the DOOM source code…

I just had this really fun idea of making a playable version of DOOM on my GitHub profile after building "Doom" in a QR code last year (https://news.ycombinator.com/item?id=43729683) and I finally stopped procrastinating to try and build it. DoomMe is DOOM E1M1 map that can run on GitHub's markdown viewer which doesn't support javascript, web assembly or even iframes it works with a stateless engine with a capture of every possible position in the map (with 64 unit distance) captured in 4 directions and stitched together using graph logic with 8000+ WebP images and markdown…
