he ??? I updated this morning and it didn't give me that.

Anyway, now mystery solved, the /usr/bin/psx4m seems still to be an old one, the /opt/usr/games/psx4m is a newer one, giving me the complete CLI parameter set.

The /usr/bin/psx4m on my N900 is actually a symlink to /opt/psx4m/psx4m.
and seems to be a leftover of a previous install ... I'll try to remove all, re-install and see what I'm left with

Thanks for letting me know something was fishy !
