Nestopia Undead Edition

What it is

Nestopia Undead Edition is a GUI build of the Nestopia emulator intended to provide a standalone graphical interface. The project describes its style as inspired by the 1990s, identifies its license as GPL-2.0 and lists version 1.99.0 as released. Nestopia UE is free. Its platform information names Linux, macOS and Windows, while a separate supported-platform listing names Windows. The repository includes source required to build the legacy Win32 release. For future GUI work, the project points to a cross-platform build handled under the Jolly Good Emulation project. Listed capabilities include save states, rewind, netplay, shader support and cheats. For a Nestopia-format cheat database, the project points users to Mighty Mo’s Cheat Code Pack. The project no longer maintains the emulator core and directs core emulation issues upstream. Contributions are reviewed when they relate to standalone GUI builds. The repository describes code outside a tagged release as volatile, so that work may change.
