I overhauled a plugin for Pokémon X/Y/OR/AS — spawn any Pokémon, shop anywhere, edit your team, know your enemy, teleport and many more!

Hey everyone! 👋 I want to share something I’ve been pouring myself into: a big overhaul of the Gen 6 CTRPluginFramework — a .3gx plugin for Pokémon X, Y, Omega Ruby and Alpha Sapphire on the 3DS (via Luma3DS). I’ll be upfront: I’m not a programmer. I’m just a curious player who’s good at testing and thinking hard about problems. Every feature here started as a real itch I hit while playing — “there should be a way to…” — and I built it out, piece by piece, in back-and-forth with Claude. The goal wasn’t to make the most powerful cheat tool; it was to make one that anyone can actually understand. What that means in practice: Every feature is named in plain language, and every single option has an info (i) button that explains it. There’s a 23-page guide built right into the plugin, written like a guided tour, not a manual. The whole UI is available in 7 languages: 🇺🇸 English · 🇫🇷 French · 🇩🇪 German · 🇮🇹 Italian · 🇯🇵 Japanese · 🇧🇷 Portuguese (BR) · 🇪🇸 Spanish. One .3gx serves all four Gen 6 games — it auto-detects which one you’re running and loads tailored content. A quick tour of what’s inside (you open everything with SELECT): 🔍 Wild Pokémon Spawner — a live, filtered list of every species; pick one (form, level, shiny) and it appears in the grass. 🐉 Respawn Legendary — sends any legendary back to its real location. 🛒 PokéMart Anywhere — a real shop in your bag, with a FREE mode and a PAY mode (prices, cart, checkout — you can never overspend). 📦 PC Box ++ — your boxes as a visual sprite grid, with a full tabbed editor (IVs/EVs, moves, ability, item, ball…) — all picked from on-screen lists, no keyboard typing. ⚔️ In-Battle Tools — Enemy Helper coaches you on the foe (what beats it, stat-by-stat compare), Change Party Stats edits your team mid-fight, and Display Enemy Stats overlays hidden data. 🗺️ Teleportation — warp to any town/route/landmark (full Hoenn + Kalos maps), plus your own saved warp points. 🎮 Mini Game Corner — a little arcade of 7 games (loot boxes, slots, prize wheel, stat duels, a random team generator, and more). ✨ Quality of life — fast text, fast walk, walk-through-walls, instant eggs, a configurable on-screen HUD, 25 color themes, Favorites, rebindable hotkeys… 📖 Complete Professor Oak Challenge guide built in — the full Oak Challenge walkthrough (by Mewlax) lives right inside the plugin, so you can follow the entire living-dex run without ever leaving your game.

I was hoping to peek inside the data of a very obscure 3DS app, let's just call it "Cupcake", but all the layout files seem to be in compressed archives. The file extensions are .zlb, and they have no identifying file headers. I thought it might be zlib compression, but I haven't found a compatible decoder. I've also tried LZ77, LZ11, and YAZ0 decompressors, both standalone and as part of Every File Explorer, with no luck.

Anyway, this is not a very important project but I'm still quite curious about these files. I'm attaching one of them in case anyone would like to take a look. There is no commercial content in the archive.
