@tuxuser: thanks for your answer. i wasn't using xelllaunch anyway, i was trying with the default *** option of powering on with eject button.
i'll do some tries with xelllaunch later today, thanks!
and i'll try to change the theme color too! yay XD
EDIT: ok, after some testing:
when booting with eject button, it hangs forever after the 0 attched controller text;
when booting with xelllaunch got from dashlaunch2.23b package, it hangs for some seconds at the same text as before, then it proceeds normally;
when booting with tuxuser's xelllaunch it's everything perfect. no hangs.
oh, and i managed to put the matrix theme back
is there an easy way to change colors on my own style? i'm a total noob, by the way. just asking.
nevermind, i found out how to do it.
