Game description

Pokemon Epsilon Emerald is an ORAS demake built on Emerald and pokeemerald-expansion. It blends Emerald’s Hoenn journey with ORAS characters, Mega Evolution, soaring and the complete Delta Episode. Pokemerrp is targeting November 14, 2026 for release; there is no playable download yet.

Fly over Hoenn on Mega Latias or Mega Latios, explore Mirage Spots, decorate and share Super-Secret Bases, and play Pinball RS. Rebuilt trainer teams, three difficulty settings and optional Nuzlocke rules give familiar battles a different pace. The game also adds new artwork and dozens of music tracks.

For an Emerald-based adventure that is already playable, explore Pokemon Monomyth and its original-region story.

Storyline

Epsilon keeps Emerald’s Hoenn story while blending in ORAS lore. Team Aqua and Team Magma are both part of the adventure, and Zinnia influences their plans. The journey continues into a playable Delta Episode that leads to Deoxys.

Features

  • ORAS in Emerald: Explore Hoenn with ORAS characters and story additions, then play the Delta Episode and catch Deoxys.
  • Soaring over Hoenn: Fly with Mega Latias or Mega Latios and discover Mirage Spots.
  • Three ways to battle: Every trainer has a rebuilt team; Normal and Hard add stricter battle rules and badge-based level caps.
  • Build and share Secret Bases: Find new locations, collect interactive decorations and share bases through mGBA savestates.
  • Pinball RS and new music: Play the Pinball Machine decoration and hear dozens of new or rearranged tracks.
  • Transfer and compatibility: Keep vanilla Emerald save compatibility and move Pokemon to Pal Park, with further Bank/Home transfer possible after checks.

Additional notes

Release target

The planned release is November 14, 2026. Epsilon is still in development, so the date and final scope can change. No playable version or download has been posted here.

Pokemon roster and battle rules

The planned roster covers all 386 Pokemon from Generations 1–3, their regional forms, later evolutions and Mega Evolutions, plus Riolu and Lucario. Hisuian forms exist in the code but are not distributed. Battles use the physical/special split and Fairy type; abilities and base stats generally follow Generation 9, while learnsets are mostly based on Generation 6 with newer moves. Hail replaces Snow and still boosts Ice-type Defense.

Saves and transfers

The creator designed Epsilon saves to work with vanilla Emerald saves, trades and save-editing tools. Pal Park transfers are planned, with Bank and Home transfer possible for compatible Pokemon. Check them in PKHeX and clean up any issues before moving them to Home; this is not a guarantee that every transfer will pass automatically.

Shiny odds

The starting shiny rate is 1/8192. The Shiny Charm from completing the Hoenn Dex adds two extra rolls, a daily Ninetales statue donation in the postgame adds one, and Masuda breeding adds five. DexNav uses a different calculation closer to ORAS.

After the first release

The creator plans bug fixes and polish after launch. Additional forms, Contest accessories, BuzzNav shopping and online-style PSS features belong to a later roadmap, not the announced first build.
