doom-sokol VS wasm4

Doom is actually quite easy to build because the source code is already structured to keep the platform-specific parts isolated (Doom was developed on NeXT workstations and then 'downported' to DOS.

For instance here's my WASM port of the Doom shareware version. This is a fork of doomgeneric, which itself is a fork of fbDoom - but midway through I noticed that all the abstractions added by fbDoom and doomgeneric are actually not very helpful for a WASM port that should run in browsers, and that I probably would have been better off forking the original source instead):

Hosted version: https://floooh.github.io/doom-sokol/

Here are a couple of real-world examples, these are all C/C++ code bases which run across Linux, macOS, Windows, iOS, Android and in browsers without porting:

Home computer emulators: https://floooh.github.io/tiny8bit/

CPU simulators for Z80 and 6502:

The shareware version of Doom:

Samples for the cross-platform libraries this stuff is built on top: https://floooh.github.io/sokol-html5/

WASM (and asm.js before it) turn the web into "just another platform" for cross-platform code bases written in any language that can compile to WASM, and that's pretty great.

I started my WASM DOOM port (https://floooh.github.io/doom-sokol/) from doomgeneric which was helpful at first, but since I had to 'slice' the various modal loops in Doom in order to make it work in a frame-callback app model it wasn't all that helpful in the end unfortunately.

Also, it would be nice if there was a WASM (soft) CPU for QEMU, which (if it existed!) would go here:

WASM4 seems to be a fantasy console with good docs that can run zig code in the browser, using the wasm target: https://github.com/aduros/wasm4/blob/main/cli/assets/templates/zig/build.zig

About assembly language, pure WAT (WebAssembly's text format) is an option if you're into that. Check out this example source (play)

Hi, could you please file a bug report? https://github.com/aduros/wasm4/issues

Posting here because there's a Rust template but no actual Rust games yet. Could be fun to see one.

By the way, the memory corruption issue was also recently reported in Go (which uses similar linker flags to Rust) https://github.com/aduros/wasm4/issues/33
