Folium review
A capable iOS 3DS emulator for cheats and multiplayer, but it requires a paid app.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Folium is a multi-system emulator for Apple devices, with support for Nintendo 3DS, Nintendo DS, Game Boy, Game Boy Advance, NES, SNES, Sega Genesis, and PlayStation 1. Its Nintendo 3DS support is aimed at iPhone and iPad users who want more than basic game launching, including save states, cheat management, update installation, controller input, and online multiplayer through custom servers. The app does not include copyrighted games or required system files.
The Nintendo 3DS feature set is the main reason to consider Folium. The Cytrus core supports importing games and required system files, while save-state loading and saving can preserve progress outside a game's standard save system. Cheat management and installation of 3DS game update files add further control for users who already maintain their own compatible files. External controller support also gives the app a broader input setup than touch controls alone.
Folium is distributed through the Apple App Store and supports iPhone and iPad, making its platform fit clear but narrow. It has no free plan, so users looking for a no-cost option should look elsewhere. Online multiplayer is available through Nintendo Wi-Fi Connection custom servers, which makes that feature relevant to users prepared to work within that setup rather than those seeking a standalone offline emulator. Choose Folium for iOS-based 3DS emulation with cheats, save states, updates, and multiplayer; choose an alternative if wider platform coverage or free access matters more.
