I'm Keeping the copies of OsmocomBB source code, from Ari 2010. l onwards , with almost 5 -6 days interval i saved  it to local drive
with date tag, as i seen few of similar project were shut down due to legal issue hence i kept copy.
thus i have more then 15 source code with date( of main branch), so far, including the one you enabled the TCH in August. month.

will it work? like if replacing some files.
.
also i just want to know there is some branches in source code apart from main branch.  can it  be download and workable ?

Kind regards,
