Emerald-Guide is a free, ad-free, offline-friendly walkthrough web app for Pokémon Emerald, one of the most beloved entries in the Game Boy Advance era. Built in TypeScript and deployed via GitHub Pages, it aims to recreate the feel of the classic Prima strategy guides — with clear maps, narrative-style story prose, and comprehensive coverage of the Hoenn region and its postgame content.

What makes this project stand out from the countless Pokémon wikis and fan sites out there:

• No ads, no trackers, no popups. Anyone who has tried to look up a gym leader's team on a mainstream gaming site knows the pain of wading through autoplay video ads and cookie banners. This is a refreshing antidote.
• Offline-friendly. Perfect for the actual use case — playing on a handheld emulator or original hardware without wanting to keep a browser tab loaded.
• Prima-style prose. Rather than dry data tables, the guide leans into narrative writing that captures the storytelling feel of the official 2003-era strategy books. That's a distinctive editorial choice.
• Postgame coverage. The description promises help "cleaning up" Hoenn after the main story, which is often where community guides fall apart.

The tech stack is straightforward: TypeScript with a static site deployment, which fits the offline-first goal well. A service worker approach would let the whole guide be cached locally after first visit — ideal for a nostalgic side project.

Who would benefit: Anyone doing a Pokémon Emerald replay or nuzlocke run, retro handheld enthusiasts (Miyoo Mini, Anbernic, etc.) who want a companion guide on a second device, and speedrun-adjacent players who need quick trainer team references without SEO-bloated fan wiki fluff. It's also a good reference project for anyone building offline-first PWAs with TypeScript.
