I’ve been tinkering with ZEsarUX custom configs as of late, and as a result have been talking to the coder of this emulator. As we have talked, he has updated his code, though it looks like RetroPie installs a pre-configured binary and not from source.
So I’d like to request that the option be added that it install from source. That way I can keep up to date with the code when talking with the author.
It downloads the previous latest version from sourceforge. It should be updated to either pull the code from sourceforge from git or updated to v4.0 because of the added systems that can be emulated with it.
