Nagaa · 2026-07-11T23:27:01+00:00

NetherSX2 - Nintendo Switch port This is a wrapper/port of the Android version of NetherSX2. It loads the original Android emulator core, patches it and runs it. It's basically as if we emulate a minimalist Android environment in which we natively run the original Android binary as is. Features Cover art — auto-download from SteamGridDB (one game or the whole library) Region flags (US / EU / JP) and a sortable library Per-game settings — override any option per title; rename and delete games Full controller remapping, stick config, deadzone, and vibration Resolution scaling up to 6× (4K), aspect ratio, widescreen / no-interlace patches, shade boost, CRT/TV shaders, and the full graphics / enhancement / audio option set Experimental network adapter (DEV9 / Sockets) — off by default, opt-in in Settings → Network Renderers Choose in Settings → Graphics → Renderer: Vulkan (NVK) — recommended; best compatibility and performance in most games OpenGL — alternative if a game misbehaves under Vulkan Cores Choose in Settings → Emulation / System → Core version: Patched (4248) — The most recent one Classic (3668) — an older build; Can get better performance on less powerful devices Credits : The AetherSX2 / PCSX2 developers for the emulator. The NetherSX2 maintainers for the patched Android builds. fgsfds for the Switch so-loader groundwork reused here. TheOfficialFloW for the original Android so-loader lineage.

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

Bulk file downloader for archive.org, per console
Smart queue, resumable, retries, survives Wi-Fi drops and restarts
Auto-extract + MD5 verification (rar3 is a known limitation)
One unified sd:/roms library, 53 systems
Add console collections on-device or from your PC over Wi-Fi
Full installed-library management (search, rename, delete)
Custom install folders, per console
Send a game straight from your PC over Wi-Fi (files you may need to decrypt on PC first)
SD card Space-aware, shows totals + free space before you commit, waits for room instead of failing, skips games you already have
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
25 languages, touch + controller, light/dark themes (I welcome PR's on the language files)

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.
