Hello again.
I'd received an advice to send a patch in the best working state i have already,
and then add the games that aren't working.
The all games should work, but hack and phantasia. Some games currently can't write
a score files, but this isn't criticall.
I'll continue to thinking about, and search for advices on how to do things in the User's HOME,
or something similar: be that "getpwid()" stuff i'd seen on stackoverflow, or just a
"chdir(getenv("SOME_ENV_VAR"));".
Regards, Vitaliy.
