Getting Started
- Tap the add button to open one game or scan a ROM folder.
- Select a game from the library to start playing.
- Open the settings drawer to choose a video filter, aspect ratio, or FDS BIOS, and to toggle HD packs, Anti-Flicker, and RetroAchievements.
- Use the in-game menu to save or load a state, view achievements, and manage FDS disks when applicable.
HD Packs
Press and hold a game in the library and choose Download HD Pack to grab a high-resolution texture pack from the in-app catalog, or Install HD Pack from ZIP to use one you already have. Games with a pack installed show an HD icon, and the pack loads automatically when the game starts.
RetroAchievements
Sign in with your RetroAchievements account from the settings drawer (or create a free one), then start a game. A badge pops up when you unlock an achievement, and the in-game Achievements menu shows your progress and points. Achievements are earned in casual mode, so save states and cheats stay available. Your password is never stored.
Cheat Manager
Press and hold a supported game in the library, choose Cheat Manager, and enable or disable individual cheats. Selections are stored separately for each game and applied the next time it starts. Modified ROMs and some regional or revision variants may not match the included offline database.
