Play as Ivan, navigating the Pokémon world to find Charon after escaping a flooded Mynoan Civilization. Catch Fakemons and Pokémon from multiple generations in this fan-made adventure, lauded on X in 2025 for its creative story (,).

The .gba ROM (~8 MB) features 65+ new songs, hand-drawn sprites, and Golden Sun-style dungeons, running smoothly on emulators like VisualBoyAdvance, mGBA, or RetroArch on PC, Mac, or Android. Legally download Pokémon Jupiter GBA ROM by obtaining a legal Pokémon Ruby cartridge and applying the hack via tools like Lunar IPS. Avoid illegal ROM sites like RomHustler due to malware and Nintendo’s copyright rules (). Buy Pokémon Ruby cartridges (~$15–$40 in 2025 on eBay) for legal patching. Catch Fakemons legally at Gigarom
