MEMU can be downloaded from
On Linux, you need to have
dnf -y install portaudio to get this,
on your Linux distro this may differ.
See the Source page.
I've included a Windows
portaudio_x86.dll in the MEMU package.

Copying of this program is encouraged, as it is fully public domain. Even the source code is included in the package. It was created on the authors time and equipment, and AFAIK, makes no use of confidential or protected intellectual property. It obviously does include copies of the MTX ROMs and some games, but this is all material already available from several places on the net, such as emulator and retro-gaming sites, and they were originally marketed by long defunct companies. Caveat Emptor.
