Very cool. Too bad this doesnt seem to work as a PWA, or am I jusr missing the button on Android Firefox?

You have to use "Add to home" menu item on Firefox for Android. But this web app doesn't seem to be a PWA.

You could send a PR. It's reasonably straightforward to add a manifest to make the app installable (https://developer.mozilla.org/en-US/docs/Web/Progressive_web...), and to use Workbox to make it work offline since it's fully static (https://developer.chrome.com/docs/workbox).

The one caveat is that a PWA needs an icon but the project doesn't currently have one, so you'd have to design, find, or LLM-generate one.

Ok. So what’s interesting here, presumably, is that this isn’t a wasm GBA emulator (which also exist and work). This is the game itself compiled to wasm. Even though no official source code was ever published, there was a community based decompilation.

tripplyons•31m ago

Yes, it a recompilation of a community decompilation!

How long until this is DMCA'd? How has the project it's based on stuck around for so long? Do I perhaps misunderstand what this is? https://github.com/pret/pokeemerald

It's a port of a disassembly that requires you to provide your own ROM. The legality of such things is a tangled web that anyone producing them needs to navigate very, very carefully.

Interesting; but the GitHub project linked seems to have the original animations from the ROM.

mathgeek•6m ago

It's mostly argued around or against the application of fair use. I suggest consulting a lawyer if you're truly interested, as it quickly gets into legalese around what constitutes ownership, distribution, etc. Throw in a lack of extensive case law and you quickly get into opinions rather than legal bases.

Confirming that saving genuinely works. Interesting stuff. Wonder if we can get trades working too.

tripplyons•6m ago

Yeah, I made sure saving worked correctly

some weeks ago I made a Gameboy emulator from zero in rust and then exported it to wasm

https://holy-lake-f6df.sdreyesg.workers.dev/

took me 3 hours with Opus. Opus knew the whole ISA, clock, bus quirks, etc. from their training without any external docs

mathgeek•33m ago

Likely because all of the external docs were already in its training set.

tripplyons•30m ago

Yes, this project was made in around 15 hours of Codex.

Next step: 100% browser javascript pokémon emerald.

gobdovan•41m ago

Any way to get sound?

tripplyons•31m ago

I have not added that yet, but it would probably be quite easy to throw a few prompts to Codex to do so.

I did a Pokémon Crystal playthrough several months ago, still great games!

I used an emulator on my laptop with increased speed so it made everything like walking and combat way faster which was really nice and I probably would have given up if it wasn't for that
