To play these fan-made NDS versions, you will typically need an NDS emulator such as SuperNDS for Android or a flashcart (like an R4) if playing on original hardware. Most ROMs come in .nds format and range in size depending on the amount of new content added.
The dual-screen layout of the NDS is fully utilized for menus, battle commands, and the Pokédex.
One of the most beloved features from HeartGold is implemented here, allowing your lead Pokémon to walk behind you throughout Kanto.

Real-time lighting and time-based events are added, which were absent in the original FireRed. How to Find and Play the ROM in Spanish
