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.
