Can I load this from OpenTTD's BaNaNaS menu?

No. This is a separate OpenTTD binary. NewGRFs you already use (CZTR, av8, eGRVTS) still install through the patchpack's own content download once this build is running.

Will my vanilla save open?

Often one way, not back. Keep vanilla OpenTTD for trunk saves and play JGRPP in its own folder.

JGR's Patchpack

Separate OpenTTD build with extra signals, programming, and map tools. Installs beside vanilla, not as a NewGRF.
