Who it suits
Generation I Pokémon save editing Players using emulators, flash carts, or dumped cartridges Users who want local browser processing and backups
Pokémon SRM Editor is a focused free tool for changing Generation I Pokémon Red, Blue, and Yellow saves. It handles Pokémon, boxes, trainer progress, inventory, raw bytes, and save history, with local browser processing and desktop backups. The main trade-offs are its limited game coverage and platform-specific launch steps. OnionOS users must also check that a save state is not hiding the battery file. Choose it when your files match the supported raw SRAM format and you need detailed control over those saves.
The full write-up
Overview Pokémon SRM Editor is a free save editor for the first-generation Pokémon games, aimed at players who want precise control over cartridge, emulator, or handheld saves. Its combination of broad data editing, diagnostics, and rollback tools makes it a strong specialist choice, while OnionOS save-state behavior and macOS’s first-launch process demand care. The editor works with raw 32 KiB .srm and .sav battery files from emulators and flash carts, including RetroArch/Gambatte, Miyoo Mini, OnionOS handhelds, Analogue Pocket, and dumped cartridges. It is deliberately focused on Red, Blue, and Yellow rather than being a cross-generation save utility. Key features Pokémon editing covers the active party and all 12 PC boxes. You can alter species, level, experience, moves, DVs, stat experience, status, original trainer, nicknames, and calculated stats. That is enough for a single correction, a rebuilt team, or extensive roster work, although the three-game scope rules it out for later Pokémon releases. Save-wide controls reach trainer identity, money, coins, badges, items, Pokédex progress, daycare, Hall of Fame records, event flags, and other stored data. This makes it suitable for fixing progression problems as well as adjusting individual Pokémon, with the obvious risk that broad changes can substantially alter a playthrough. Save version history records diffs and provides one-click restoration. Diagnostics report problems such as checksum mismatches and invalid values without refusing to open the file, so an unusual or damaged save can still be examined and repaired instead of being rejected outright. Protection is handled differently across versions. The desktop application creates a timestamped .bak beside the original before saving over it. The browser editor keeps the original bytes downloadable, and its WebAssembly processing means the save file never leaves the browser for upload. Desktop builds can also discover Generation 1 saves on Miyoo Mini and OnionOS SD cards, reducing manual file hunting. On OnionOS, an automatically loaded save state can conceal the actual battery save. The editor warns about that situation and offers to rename the state, but users still need to understand which file their game will load. The macOS application is not notarized by Apple; first launch requires Finder’s right-click Open route or removing quarantine with xattr . Pricing Plan Price Includes Free free Web app and desktop app for Pokémon Red, Blue, and Yellow save files There is no trial because every supported function is free, with no paid tier or seat and quota structure to weigh. Choose it when you need a Generation 1 editor; it offers no broader game coverage in exchange for that focused scope. Platforms Pokémon SRM Editor runs on web, macOS, Windows, and Linux. The web route is convenient for local, private editing in a browser, while desktop versions add timestamped backups and SD-card discovery. macOS users should plan for the notarization workaround on first launch. Who it's for This is for Pokémon Red, Blue, and Yellow players managing emulator, flash-cart, Analogue Pocket, Miyoo Mini, OnionOS, or dumped-cartridge saves. It fits community members correcting progression, tuning party or box Pokémon, or preserving a sequence of revisions. It is not the right tool for games outside Generation 1 or for anyone unwilling to resolve OnionOS state-file ambiguity. Pros and cons Pros Deep Generation 1 coverage: party, 12 PC boxes, trainer data, progression, items, and event records can all be edited. Useful recovery controls: diffs, one-click restore, timestamped desktop backups, and downloadable browser originals limit the cost of a mistake. Private browser workflow: WebAssembly processing keeps the save file from being uploaded. Flexible source support: emulator, flash-cart, handheld, Analogue Pocket, and cartridge-dump saves are covered. Cons Only Red, Blue, and Yellow: players working on other Pokémon generations need another editor. OnionOS requires attention: an auto-loaded state can shadow the battery save, even with the warning and rename option. macOS setup is less direct: the unsigned, unnotarized app needs a special first launch. Alternatives For a wider directory of tools, browse Game save editors . Palworld Save Pal is the better fit for Palworld players who want every feature under a free plan across web, desktop, and mobile platforms.

Look elsewhere for later Pokémon generations, another game, or a desktop experience without macOS’s first-launch hurdle and OnionOS’s save-state complication.
