Inject Tera Raid and Mass Outbreak event data into Pokemon Scarlet & Violet save files directly on Nintendo Switch.

For Pokemon Scarlet / Violet version 4.0.0 only.

Note: Use at your own risk. The author is not responsible for any data loss or damage to your save data. If you need to restore a backup, use a save manager such as Checkpoint or JKSV to import the backup files back onto your Switch.

Features

Profile & Game Selection - Pick any Switch user profile and choose between Scarlet or Violet.
Raid Event Injection - Inject Tera Raid event data from prepared event folders into the save file.
Mass Outbreak Injection - Inject Mass Outbreak event data (Paldea / Kitakami / Blueberry zones).
Combined Inject - Stage a raid and an outbreak together; one Inject press commits both.
Event Clearing - Remove active raid or outbreak event data independently.
Automatic Backups - Save data is backed up to SD card before any modification.
Round-Trip Verification - Encryption integrity is verified after decryption to ensure data safety.
Theme Support - Switch between Default (dark) and HOME (light pastel) themes.
Validity Cache - Event folder validation results are cached to disk for instant browsing.
Joystick & D-Pad Navigation - Full analog stick support with repeat on all screens.

Installation

Requirements

Nintendo Switch with CFW.
Title override mode required - Launch via a game title, not the album (applet mode is not supported).
Pokemon Scarlet and/or Violet save data on the console.
SD card with sufficient free space for backups.

Instructions

Copy EventRaidInjector.nro to sdmc:/switch/EventRaidInjector/ on the SD card.
Place raid event folders in sdmc:/switch/EventRaidInjector/events/.
Place mass outbreak event folders in sdmc:/switch/EventRaidInjector/outbreakevents/.
Launch via title override (hold R while opening a game).

Raid Event Folder Structure

Each event folder placed in events/ must contain:

MyRaidEvent/
  Identifier.txt              # Event name/description (first line is displayed)
  Files/
    event_raid_identifier      # 4 bytes
    raid_enemy_array           # 30,000 bytes
    fixed_reward_item_array    # 27,456 bytes
    lottery_reward_item_array  # 53,464 bytes
    raid_priority_array        # 88 bytes

Binary files support version suffixes (checked in order): _3_0_0, _2_0_0, _1_3_0, or no suffix.

Outbreak Event Folder Structure

Each event folder placed in outbreakevents/ must contain:

MyOutbreakEvent/
  Identifier.txt              # Event name/description (first line is displayed)
  Files/
    pokedata_array_*           # 3,608 bytes - Pokémon list (required)
    zone_main_array_*          # 768 bytes  - Paldea zones (required)
    zone_su1_array_*           # 768 bytes  - Kitakami zones (required)
    zone_su2_array_3_0_0       # 768 bytes  - Blueberry zones (optional, 3.0.0+ only)

The * in filenames is a version suffix: _3_0_0 for 3.0.0-era events, _2_0_0 for 2.0.0-era events. The injector picks the newest available.

The Blueberry zone file is optional. Outbreak BCAT shipped in update 2.0.0 (Teal Mask), so 2.0.0-era events do not include zone_su2_array. If the save doesn't have the Indigo Disk DLC, the Blueberry block is skipped automatically.

Both formats are compatible with Tera-Finder.

User guide

Options:

Select Profile - Choose the Switch user profile with save data.
Select Game - Pick Scarlet or Violet (a backup is created automatically).
Browse Event Folder and/or Browse Outbreak Folder - Select an event from each list (validity is shown for each folder).
Inject Event - Commits every staged selection (raid and/or outbreak) into the in-memory save.
Save & Exit - Persist changes to disk and close the app.

The right-side panel shows the staged state for each kind: [Pending - press Inject], [Injected], [Cleared], or [None selected].

Combining raid and outbreak

Both kinds can be staged before injecting:

Browse Event Folder > pick a raid > it appears in the panel as [Pending].
Browse Outbreak Folder > pick an outbreak > it appears in the panel as [Pending].
Press "Inject Event" once > both are written, both flip to [Injected].
"Save & Exit".

If only one slot is pending, only that one is injected; the other slot is left as-is.

Clearing

"Clear Event (Inject Null)" - Zeros all raid event blocks. Used to remove an active raid event.
"Clear Outbreak Event (Inject Null)" - Zeros all outbreak event blocks while keeping the BCAT outbreak system enabled (matching Tera-Finder's null-event behavior).

Clearing is immediate (it writes directly to the in-memory save and marks it dirty); the user does not need to press Inject after a Clear.

After injecting a raid event, the system date may need to be advanced by 1 day in-game to refresh the active raids. The same applies to outbreak rotations.

"Clear Cache & Revalidate Events" can be used if event folders have been added or modified and validation results need to be refreshed. This clears the cache for both events/ and outbreakevents/.

Backups

Backups are created automatically in:

sdmc:/switch/EventRaidInjector/backups/{ProfileName}/{Game}/{ProfileName}_{Timestamp}/

If there isn't enough free space (2x save size), the user is prompted to continue without a backup.

Themes

Default - Dark theme with gold and cyan accents.
HOME - Light pastel theme inspired by Pokemon HOME.

Theme preference is saved to theme.cfg and persists across sessions.
