General Notes & Version Difference

Not all 1025 Pokemon are available in HeartGold Generations. Due to the current limitations of the hg-engine, a number of Pokemon remain unavailable. These are primarily Legendaries, along with some standard species that rely on non-implemented abilities (such as Palafin or Morpeko) or lack sprite assets entirely (like Bounsweet or Arctovish). As a result, completing the full National Dex isn’t possible—but that’s not the focus of this hack.

To accommodate different player preferences, the game is available in three distinct versions. Each offers a slightly different experience, tailored to different playstyles. See below for version differences.

The Lite and Vanilla versions are no longer being updated starting from version 2.0. They are only available up to version 1.1. If you wish to play that version of the game, please refer to the old features list.

Full Version	Lite Version	Vanilla Version
Expanded Dex	Expanded Dex	Regular HG Dex
Free Rare Candies at Start	Free Rare Candies after 8 Gyms	Free Rare Candies after 8 Gyms

Creator Notes

The entire HeartGold Generations project is now open source. The goal is to help spark interest in Gen 4 ROM hacking and show what’s possible with the hg-engine—especially for those who may not have realized how much can be done with HeartGold as a base.

All three versions of the hack are available as separate branches on the GitHub repository, making it easy to fork and create custom versions. Community contributions and personal variations are encouraged.

Known Bugs / Issues

MelonDS crashes after Hall of Fame.
Ariana Double battle in Mahogany town can cause crashes when fainting both opponents at the same time.
- Save often
Health Absorbing moves (absorb, giga drain) don’t heal you on “not very effective” opponents.
- Just deal with it, I guess
Generic Heartgold emulation bugs like flickering sprites or following pokemon etc
- This is not a bug from my hack, its intrinsic to emulation. Just save in-game the moment you see a glitch and reload.
No Guard ability seems to not work, maybe just with Fury Cutter
