GameWasm: C++ Game to WebAssembly Toolkit

Developers porting legacy C++ games to WebAssembly wrestle with pointer-size quirks, unsafe struct serialization, native debugging headaches, and brittle integration with modern frameworks. GameWasm automates build flags, injects pointer‑safe serialization helpers, bridges native debugging to the browser, and supplies ready‑made Svelte/React/Vue modules, turning a weeks‑long migration into a days‑long sprint.

Comment on: Ported my C game to WASM, here's every bug that I hit

I've been porting Micropolis (SimCity Classic) to WASM / WebGPU / Svelte 5. Emscripten + Embind compile the C++ engine and glue it to TypeScript/Svelte/Runes/Reactivity; TypeScript owns UI, rendering, and callback handlers.I agree with the article's main lessons: wasm32 pointer size, don't serialize structs with pointers, debug native 32-bit when you can, WebGL/WebGPU is stricter than desktop GL, Emscripten export flags still bite. I hit some of the same categories; the parts that were actually tricky for Micropolis are below.Svelte 5 runes ($state, $derived, etc.) work in plain .ts modules, n
