Pokémon SRM Editor

Overview

Pokémon SRM Editor is a save editor for Pokémon Red, Blue, and Yellow. It is best suited to players working with Generation 1 saves who want detailed control over Pokémon and wider game data. Its broad editing and recovery tools make it a strong focused choice, though it is not a general-purpose editor.

Key features

The editor opens raw 32 KiB .srm and .sav battery saves from emulators, flash carts, Miyoo Mini and OnionOS handhelds, Analogue Pocket, and dumped cartridges. Users can change Pokémon in the party and all 12 PC boxes, including species, level, experience, moves, DVs, stat experience, status, original trainer, nicknames, and calculated stats. That range supports both a quick correction and extensive roster changes, while the three-game limit rules it out for saves from other Pokémon generations.

Editing extends beyond Pokémon to trainer identity, money, coins, badges, items, Pokédex, daycare, Hall of Fame, event flags, and other saved data. Version history provides diffs and one-click restore, and diagnostics flag issues such as checksum mismatches and invalid values without blocking opening or fixing a file. Those checks and rollback options are valuable when changing a save whose state may be unusual or damaged.

Protection depends on the edition: the desktop app creates a timestamped .bak beside the original before overwriting it, while the web app keeps the original bytes downloadable. The browser editor runs via WebAssembly and never uploads the save, a useful privacy advantage for players who prefer to edit in a browser. Desktop users can also have the app discover Gen 1 saves on Miyoo Mini and OnionOS SD cards.

On OnionOS, an auto-loaded save state can shadow the battery save; the app warns about this and offers to rename the state. That warning addresses a specific compatibility hazard, but users should still check which save they intend to edit. The macOS app is not notarized by Apple, so first launch requires opening it through Finder’s right-click menu or removing quarantine with xattr.

Pricing

The Free plan costs nothing and includes the web and desktop apps for Pokémon Red, Blue, and Yellow save files. There is no paid plan or trial to weigh against it. For a player editing one of those games, the free offering includes inventory, progression, and character-stat editing, along with automatic backup; its main limitation is game coverage, not a reduced feature tier.

Platforms

Pokémon SRM Editor supports web, macOS, Windows, and Linux. The web version avoids uploading the save and preserves the original bytes for download; desktop versions add timestamped backups, and the desktop app can discover saves on Miyoo Mini and OnionOS SD cards. macOS users should expect the extra first-launch step because Apple has not notarized the app.

Who it's for

This is the right choice for players who need to edit Red, Blue, or Yellow saves across Pokémon, trainer details, inventory, and progression, particularly if save history, diagnostics, or a local backup matter. It is less suitable for anyone editing games outside those three or unwilling to handle OnionOS save-state conflicts or macOS’s first-launch restriction.

Pros and cons

• Pro: Detailed editing covers Pokémon across the party and all 12 PC boxes, plus substantial trainer and game data.
• Pro: History with diffs and one-click restore, diagnostics, and version-specific protection reduce the risk of losing track of changes.
• Pro: Browser editing keeps the save on the device, and the free plan includes both web and desktop apps.
• Con: Support is limited to Red, Blue, and Yellow, so it will not serve players editing other generations.
• Con: OnionOS save states can shadow battery saves, and the macOS app requires a workaround at first launch.

Verdict

Look elsewhere if you need support beyond Generation 1, or if the OnionOS and macOS caveats make its workflow a poor fit.
