When making a save state, all the system components are "fast forwarded" to a
safe state that can be serialised. If delayedSync (called "Coprocessor Fast
Sync" in the UI) is enabled, this works perfectly. If it is disabled, the
accurate coprocessor synching interferes with the save-state creation, leading
to the game crashing or (worse) the emulator freezing.
Star Fox is a good test case - repeatedly saving state and loading it will very
quickly cause the game to run super-slowly, hang, or crash.
Ideally, somebody should dig into exactly what coprocessor syncing is doing
that breaks the assumptions of the state-saving code, but given how complex
the whole thing is, and given that it doesn't affect hardware emulation
accuracy (real hardware can't save states at all), it's easiest to just force-
enable delayedSync while a save-state is in progress.

- Multi-threaded PPU graphics renderer
- Speed mode settings which retain smooth audio output (50%, 75%, 100%, 150%, 200%)
- Built-in games database with thousands of game entries
- Built-in cheat code database for hundreds of popular games (by mightymo)
- Built-in save state manager with screenshot previews and naming capabilities
- Customizable per-byte game mappings to support any cartridges, including prototype games
- 7-zip decompression support
