Technical Specifications

What Bonito Days Is

Bonito Days sits in the action-platformer space, which means the moment-to-moment loop is about movement and timing rather than long narrative exposition. Studio Somewhere built the game for the Switch specifically, and the release arrived on October 14, 2021 as an eShop title. The file you are downloading carries Title ID 0100ACD0154CC000, which is the identifier your installer and any save-management tools will reference once the game is on the system.

The package is region-tagged for USA, EUR, and JPN, so it is not locked to a single storefront territory. That flexibility matters if you keep a mixed-region library or if you are running an emulator configured for a particular region. The game ships with seven language options: English, Japanese, French, Spanish, Italian, Korean, and Chinese. For a small-studio platformer, that is a broad localization spread, and it makes the title easier to recommend to households where English is not the primary language.

If you enjoy compact platformers with a clear arcade feel, the same library holds titles like Acorn Avengers Switch NSP (eShop), which follows a similar pick-up-and-play philosophy.

Key Features

• Action-platformer gameplay — the core loop centers on precise movement and level traversal, the genre pairing Studio Somewhere lists for the title.
• eShop NSP format — the download is a .NSP package, installable through Tinfoil or DBI Installer on modded hardware.
• Multi-region release — tagged for USA, EUR, and JPN, so region matching is not a blocker.
• Seven supported languages — English, Japanese, French, Spanish, Italian, Korean, and Chinese are all included in the base package.
• Compact footprint — at 624MB, it takes up very little space on internal storage or a microSD card.
• Emulator compatible — the NSP can be loaded in YUZU or Ryujinx for play on a Windows PC.
• Low firmware floor — requires base firmware v12.1.0, so older consoles are not shut out.

Who This Download Is For

You will get the most out of this package if you already have a jailbroken Switch and a working installer workflow, or if you run a Switch emulator on Windows and want a small, self-contained platformer to add to your collection. The 624MB size means it downloads quickly even on a modest connection, and it will not crowd out larger titles on a full microSD card.

It is less suited to anyone expecting a sprawling adventure. Bonito Days is an eShop-scale release from a small studio, and the content scope reflects that. If you want a long campaign with deep systems, look elsewhere in the platformer catalog — for instance, Scurge: Hive Switch NSP (eShop) offers a very different, more exploration-heavy take on the genre.

Firmware and Installation Guidance

The base game requires firmware v12.1.0. If your console is on that version or newer, you are in range. Before installing, confirm your custom firmware setup is current, because an outdated installer is a common cause of failed NSP installs. Tinfoil and DBI Installer are the two tools referenced for this package; either will read the .NSP and write it to your system or SD card.

For emulator users, YUZU and Ryujinx both accept NSP files. You will need to point the emulator at your keys and firmware files first — the game package alone is not enough to boot on PC. If you are new to the process, the jailbreak and hack guide linked from this site's FAQ section walks through the console side, and the same FAQ covers extracting multi-part RAR archives if you run into a split download.

One practical note: this listing provides the base game only. No update or DLC package is included, so treat the version field as the shipped 1.0 build rather than a patched release.

Pros & Cons

Pros

• Small 624MB download that installs fast and stores cheaply.
• Region-free across USA, EUR, and JPN tags.
• Seven-language support built into the base package.
• Runs on firmware as old as v12.1.0.
• Works with both major Switch emulators on Windows.

Cons

• Base game only — no update or DLC bundled.
• Requires a modded console or an emulator; it will not run on stock hardware.
• Small-studio scope means less content than full retail platformers.
• Download links route through link shorteners, adding a step before the file.

Download Links and File Details

The base game NSP is 624MB. Multiple mirrors are listed below so you can pick the host that works best from your region. No password is set on the game files.

Mirrors: MegaUp | Send | RapidGator | Datanodes | Gofile | 1Fichier

For extracting any RAR archives, use WinRAR or 7zip. Keep your extraction tool updated — older WinRAR builds sometimes prompt for passwords on archives that have none. If an archive reports a CRC error or appears damaged, re-download that part rather than troubleshooting the installer.

Trust and Version Notes

Publisher and developer are both listed as Studio Somewhere, and the original release date is October 14, 2021. This is the eShop NSP build, identified by Title ID 0100ACD0154CC000. Because no changelog or update package was supplied with this listing, you should verify the version number inside your installer after adding the file — that is the reliable way to confirm exactly what build you have. If a link is dead, use the reupload request page rather than hunting for a mirror elsewhere.

If you want to broaden the collection further, Earnest Evans Collection Switch NSP [Update] (eShop) is another option worth comparing, and unlike this package it ships with an update included.
