Owh, I make some progress in this.
My player has ATJ2051H chip and firmware I flashed is for ATJ2085, or something like that, The reason is button order. At my configuration 01 is code for "Off button", as I think. But 01is binded to some periodical action (as I understand it have to be key scanner or something like that).
So, if I change this value to 00 in KY_HARD.DRV, player stops turning off.
And now I have the other problem: only one Next button works by default. By some tests I found out codes of Previous and Play button.
But they don't work properly, they work only being binded to physical Next button. I think it happens because of that damned keyscanner (kind of there must be something to scan other button codes). If someone knows how does keys system work (even on ATJ2085), please tell me little about it, and if possible, point me to key table for my chip.
