NostalgiaNes is a high-quality NES emulator utilizing the latest FCEUX revision. It features a modern, user-friendly interface and a customizable virtual controller, allowing users to adjust button sizes and positions. The emulator supports game progress saving and loading with 8 manual slots and an autosave option, along with the ability to share save states via Bluetooth, email, or Skype.
A standout feature is the rewind function, enabling players to reverse time briefly if they make a mistake. The Wi-Fi controller mode lets multiple devices connect, turning smartphones into wireless gamepads for multiplayer experiences, supporting up to four players. Other notable features include Zapper emulation, turbo buttons, and support for PAL and NTSC video modes. The app delivers hardware-accelerated graphics, stereo sound at 44100 Hz, and supports HID Bluetooth gamepads.
NostalgiaNes supports files with .nes and .zip extensions but does not include any games. Users must provide their own ROMs, which can be located anywhere on their SD card. This lite version is ad-supported, with certain features, such as manual saving/loading and rewinding, available only when ads are displayed. The app is GPLv3-licensed, and users can download its source code. Users are encouraged to send feedback and suggestions via email.
