Nestopia UE

Nestopia UE (Undead Edition) is a fork of the original source code, with
enhancements from members of the emulation community. This includes
support for new platforms, and bug fixes in the emulator core.

1.46.2 is another quick unix-only bugfix release.

September 23, 2014

1.46.1 is out. This is a unix-only release, and only contains small bugfixes
that should have been taken care of before the last release, but weren't. It
happens when you're excited to do a release after over a year. A Windows build
based on the "unix" port is coming, as soon as SDL 2.0.4 is officially released.

September 1, 2014

1.46 is out.
The main highlight is that the unix/cross-platform build has been 98% rewritten.
The changes made in this release cycle should make everything much more
maintainable, and enable me or anyone else to add frontend features more easily.

Plans going forward:
The cross-platform release will be brought up to parity with the legacy Windows release.
The only thing left to do at this point is implementing the exotic input devices. That
will be a focus for the next release cycle.
The libretro release will continue to be a rolling release.
The legacy Windows release is still being maintained for the time being, but
it will be discontinued as soon as the new cross-platform build is capable of
replacing it.
The core is going to receive more focus in the future as well.


Nestopia UE officially supports:

A libretro port is also available.
