Wow, another player with a new firmware version.
Looking promising.
Bayu, can you browse for individual files with your player? Tadad's one can so would be interesting to see what your player is capable of.
Updated versions of the s1fwx tools should be on the
http://www.s1mp3.de site. I will check it often and if a new version is released, it will certainly be available on this site.
