Some adapters feature additional hardware for various things, such as audio emulation, copy protection bypass, joystick plugs, reset support, and more!

Loading is always instant. No need to take a coffee break while your program is loading. Built-in versioning system preserves your original files (on systems/configurations that support saving).
