What Nestopia Undead Edition is

Nestopia Undead Edition is a free graphical-interface project for the Nestopia emulator, intended to provide a standalone GUI. The maker’s site lists Nestopia UE 1.99.0 as released, and the project identifies its license as GPL-2.0. The listed plan costs nothing, with no price or usage limits stated. The product platform listing names Linux, macOS, and Windows, while the supported-platform listing specifically names Windows. The repository contains source needed 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. Nestopia UE includes save states, rewind, netplay, shader support, and cheat support. 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 tagged releases as volatile, so that work may change.
