Headline features

Three regions, one save

Kanto, the Sevii Islands and Hoenn in a continuous journey — with extended play after each regional League.

All 1,025 Pokémon

Every species and form obtainable in-game — no trading, no event codes. Failed legendary encounters return the next day.

Modern battle systems

Physical/Special split, Fairy type, plus Mega Evolution, Dynamax, Z-Moves and Terastallization — one gimmick per battle, tied to held items.

Post-game meat

Redesigned Battle Frontier, daily rematches for all 32 Gym Leaders, and trainer/wild scaling to your team.

Secret Dens

Secret Bases replaced by mini-dungeons holding rare Pokémon and items — some with hidden abilities.

QoL everywhere

Nature Mints, unlimited Pokéblocks, a SELECT quick-run toggle in battle (v1.0.3+), stronger EXP catch-up for underleveled Pokémon.

How to play it

  1. 1
    Get the patch

    Download the latest release from the GitHub project (specimendelta/Pokemon-Gen-3-Evolved) — v1.0.16 as of November 12, 2026. It's a .bps file, not a ROM.

  2. 2
    Patch your own FireRed

    You need your own unmodified Pokemon FireRed (USA, v1.0) ROM. Apply the .bps with a patcher like Floating IPS (FLIPS) or an online BPS patcher.

  3. 3
    Run it in a GBA emulator

    mGBA is the reliable pick on desktop and mobile. Keep the patched file name stable — a renamed ROM orphans your .sav.

  4. 4
    Updating versions

    Patches keep save compatibility — if the emulator starts a new save after updating, rename the new ROM to your old filename or copy your .sav to match.

FAQ

Is it finished?

It's a complete release under frequent patching — v1.0.16 fixed a progression-ordering bug involving Archie and Sootopolis, days after launch.
