Curse of the Sea Rats has received several significant updates on the Nintendo Switch to address launch issues and improve gameplay. As of early 2026, the game is widely considered much more polished than its initial release. Latest Updates and Major Changes
Version 1.3.7 (Released June 2023): This major patch focused on the Combat System.
Animation Cancelling: Attacks can now be canceled with jump and parry actions for faster, more dynamic gameplay.
Control Tweaks: Movement and combat responsiveness were improved, and hurt animations were shortened.
General Fixes: The map UI was updated, pitfall deaths were disabled, and the end game was smoothed out.
March 2025 Patch: A newer update reported by players improved late-game stability and fixed specific exploits, such as the "fireball soul" farming method. Switch File Types (ROM/NSP) In the context of the Nintendo Switch:
NSP (Nintendo Submission Package): This is the standard file format used for digital game installations, updates, and DLC.
Installation: For users of custom firmware, updates are typically installed via tools that manage .nsp files, while legitimate users update directly through the Nintendo HOME Menu. Exp Farming Post-Patch
Since some exploits were patched, players recommend the Temple area on the far right of the map for farming experience. Specifically, a ghost enemy near a save point in this area can be farmed for roughly 300 EXP per kill by repeatedly exiting and re-entering the screen.
Title: Curse of the Sea Rats (Switch NSP/Update) – The Metroidvania Swashbuckler
Overview: Curse of the Sea Rats is a hand-drawn, animation-rich Metroidvania platformer. Players are transformed into rats by a pirate witch and must battle through colonial-era Ireland and beyond to break the curse. It features four playable characters (co-op available) and a unique "spectacle fighter" inspired combat system.
NSP/Update Context (For Technical/Backup Use): As with many indie Switch titles, Curse of the Sea Rats saw several post-launch patches. Key updates (e.g., v1.0.1, v1.0.4) focused on:
- Improving load times (a major complaint in the base 1.0.0 release).
- Fixing soft-locks in co-op mode.
- Balancing enemy damage and hitbox detection.
- Adding a mini-map icon for the key "Davy Jones' Compass."
Important Note for ROM/NSP seekers: While NSP/NSZ dumps (base game + update) are circulated for backup manager tools (like DBI or Tinfoil), be aware:
- The game requires firmware 15.0.1 or higher (for updates v1.0.4+).
- The base NSP is ~1.8 GB; the update patch is ~200 MB.
- No "Day 1" patch unlocks full content – the game's true ending requires all four characters' stories completed, which is in the base code, not just an update.
Legal/technical reminder: Sharing or linking to ROM/NSP files is copyright infringement. This information is for educational purposes regarding update contents and backup management of legally owned copies only. Always support the developers (Petoons Studio) by purchasing from the eShop or physical retailers.
If you need help identifying whether an update NSP you have matches the latest patch notes (v1.0.5 as of late 2024), refer to the in-game version number on the title screen.

Curse of the Sea Rats (Switch) Review - Nintendo World Report
Curse of the Sea Rats is a "ratoidvania" adventure featuring hand-drawn animations, where players control four brave rats turned into rodents by a pirate witch. Regarding the
files for the Nintendo Switch version, here is an informative breakdown of what these files represent and how they function within the Switch ecosystem. Core File Types NSP (Nintendo Submission Package):

Players can swap between four characters, each with distinct playstyles: A bold fencer with balanced stats. A heavy hitter utilizing long-range strikes. A swift warrior specialized in agile combat. A defensive powerhouse. Version Management
On the Nintendo Switch, the system treats the base game (NSP) and the Update as separate entities that "stack." To ensure the best experience, players must ensure the Update version matches the base game's region (e.g., North America, Europe, or Japan). Running the base game without the latest update may result in encountering day-one bugs that were patched shortly after the 2023 release. Technical Note
While NSPs are the standard for digital distribution, they are intended for use on retail hardware through the official Nintendo eShop. Utilizing these files on emulators or modified hardware falls into a legal gray area regarding copyright and Terms of Service. Always ensure you are sourcing files through legitimate channels to support the developers.
