The Pokémon ROM hacking and fan game community shows no sign of slowing down. With each passing month in 2025, developers continue to deliver jaw-dropping projects blending creativity, nostalgia, and modern game design. June 2025, in particular, saw some of the year’s most exceptional Pokémon ROM hacks and fan-made titles released or updated — offering new regions, original storylines, thrilling battle systems, and even voice-acted cutscenes.
Whether you’re an old-school player nostalgic for FireRed remakes or someone seeking entirely new fan-made worlds, this list of the best Pokémon ROM hacks and fan games of June 2025 will help you find your next unforgettable Pokémon journey.
What Are Pokémon ROM Hacks and Fan Games?
Pokémon ROM hacks are modified versions of Nintendo’s original Pokémon games coded on platforms like FireRed, Emerald, or Crystal. Fans modify these ROMs to enhance visuals, tweak mechanics, and introduce entirely new stories, Pokémon, and gameplay modes, while maintaining the beloved Pokémon core.
Pokémon fan games, on the other hand, are built from scratch using engines like RPG Maker XP or Unity. These offer complete originality with new worlds, characters, and soundtracks — often rivaling official Pokémon games in depth and storytelling.
