About Pokemon Iridium
Pokémon Iridium is built for tactical battles, with elemental terrain, weather-aware team building and competitive-style balancing. SauceyaTTa created this English NDS hack based on HeartGold, currently Demo 0.3. It includes fully implemented Mega Evolutions, generation-accurate animated moves and modern items such as Loaded Dice. Hard level caps shape progression, while Casual and Elite modes handle them differently. Press L for the Porta-PC anywhere, and R to relearn moves outside gauntlet fights. The updated bag, enhanced summary screens, IV/EV viewer and 60 FPS battles support faster decision-making.

Pokémon Iridium is sauceyaTTa's in-development HeartGold-based NDS project, with its own East Iridia setting rather than a Johto remake. A demo was announced in May 2025, but the available public sources do not establish the demo's endpoint, a revision-specific base ROM, or a verified patch-only download.
Before you patch
- No patch link is listed here. The creator’s public release announcement was found, but an official archive containing a ROM patch could not be verified.
- Public documentation identifies this as a HeartGold NDS hack, but does not give a region or revision for the original ROM.
baseRomis deliberately blank rather than guessed.
Who it’s for
Iridium is for players willing to follow an in-development project instead of expecting a finished replacement for HeartGold. sauceyaTTa’s developer profile still labels it “in-dev.”
The project overview says the story begins in East Iridia, not Johto, Kanto, Sinnoh or another existing map, and describes a planned two-region setting. That makes the current trade-off clear: the premise is broader than the publicly documented demo scope. The sources available for this note do not state how many Gyms, League battles or postgame content the demo includes.

Pokemon Iridium: common questions
- Is Pokémon Iridium finished?
- No. sauceyaTTa's public developer profile still describes Pokémon Iridium as "in-dev". Treat the released material as a demo rather than a completed two-region game.
- Is this a modified Johto or Kanto map?
- No. The published project overview says the story starts in East Iridia and is not set on a pre-existing Pokémon region. It describes a new story planned across two custom regions.
- Which ROM revision should I patch?
- The available project overview identifies HeartGold as the base game, but it does not specify a region or revision. Use no guessed revision; a patch source should state the exact target before you apply it.
- Where is the official patch download?
- A creator-authored Reddit announcement confirms a demo release was announced, but no opened creator source verified a patch-only archive or its contents. This note therefore does not link a download.
