Hi again. I found a glitch but resolved it. It seems that the firmware i used works, except for the f**king speaker. So as i know very tiny bit of russian i searched the web and found A 100% WORKING FIRMWARE. It's from the russian glacier-type distributor, called DaZed. Their 9.0.50 firmware worked perfectly... And now i have 4 games on the player hehe

.
