Audio & timing
Sound that stays in sync
SPU2 emulation tries to match what the real console did: voices, reverb, and streaming audio all depend on the emulated CPU keeping pace. When your frame rate dips below 100% speed, music and dialogue often stretch or stutter—that is usually a performance issue, not a “broken sound driver.”
- Latency tuning for Bluetooth controllers vs. wired pads.
- Async mix options—use wiki guidance per game; some titles hate async.
- Dumping audio for debugging when a cutscene loops forever.
- MTVU and other thread tweaks can change how “tight” the core feels.
Interface
Big picture UI features
Game list & covers
Scan folders once, then launch from a sortable list with cover art when you add PNGs sidecar-style.
Per-game settings
Store renderer choice, aspect ratio overrides, and speedhack presets per serial so RPGs and racers do not fight each other.
Achievements (where supported)
RetroAchievements integration for compatible sets—great for replaying classics with goals.
Fullscreen & multi-monitor
Exclusive fullscreen, borderless, and DPI-aware scaling so 4K panels do not look blurry by accident.

“Features are only useful when you understand the trade-off: internal resolution scales GPU load; software mode trades GPU for CPU; patches can fix HUD alignment but break FMV.”
