HaulNX → a homebrew ROM library downloader / manager for Switch (archive.org → sd:/roms)

digdat0 · Jul 27, 2026

Full disclosure: This app was built entirely with AI (Claude Code) and its open source. I understand there is alot of AI code pushback, and I get it .. feel free to call it AI slop. This was formerly TicoDL+, but given the recent increase in functional emulators, I broke it out it from being Tico specific to being a general downloader supporting 50+ consoles and thus greater emulator support.

HaulNX is a Nintendo Switch homebrew that browses and downloads game files from archive.org into one central library at sdmc:/roms/<console>/, decompressing archives along the way. Point your emulators at that folder once and everything you download from then on just appears. It doesn't play anything itself, it's the download manager that feeds Tico, RetroArch, DuckStation, PPSSPP, melonDS, etc.

HaulNX ships with no ROMs, no collections, and no credentials, it's an empty downloader. You provide your own archive.org item IDs (and optionally your own archive.org keys for restricted items). Nothing is bundled or linked. This project doesn't condone piracy or copyright infringement, please don't post ROM sources or copyrighted content in the thread; keep it about the app. You're responsible for the laws that apply to you in your locale.

Features

Companion PC app allows you to build collections with a real keyboard, verify each source against archive.org before you commit, and push straight to the Switch over Wi-Fi

53 consoles supported: nes, fds, snes, n64, gb, gbc, gba, nds, 3ds, gc, wii, wiiu, virtual-boy, pokemon-mini, game-and-watch, sg-1000, master-system, game-gear, genesis, sega-cd, sega-32x, saturn, dc, psx, ps2, psp, pc-engine, pc-engine-cd, supergrafx, pc-fx, neo-geo, neo-geo-cd, neo-geo-pocket, neo-geo-pocket-color, atari-2600, atari-5200, atari-7800, atari-lynx, atari-jaguar, wonderswan, wonderswan-color, colecovision, intellivision, odyssey2, vectrex, channel-f, 3do, cd-i, supervision, atomiswave, naomi, arcade, fbneo

Emulator setup: The wiki has a page for emulator setup (let me know if I'm missing any). All you need to do is point your emulator to the installed folder for that console. If your emulator doesn't support setting a folder, set a custom path in HaulNX to that console's folder location, and the app puts games there.

I've made alot of updates, shifting the focus of the app to be a Switch ROM manager. There are so many emulators popping up right now, managing roms per emulator in their own folder was challenging. This centralizes roms into a single folder structure, simply point your emulator to the folder and you are good to go. You can also scan for emulators and app updates so you dont have to chase git updates and manually drop files onto your sd, new steamGrid box art, de-dup and tidy your library, view storage usage of roms and scan for large files, verify against NoIntro/Redump DAT files, manage your SD via wifi from the desktop app, and tons of other things as well. I welcome any feedback on the app. I'm moreso building it for my own usage, but hope others find it useful.

Good homebrew, well-organized interface—unlike NExPS, which has a terrible interface.
