Using info from a previous thread I found I could play a R1 version of Full Metal Jacket today, by continually pressing "1" repeatedly as the disc loads - seems to bypass something, and plays the VOB files (bypassing film menu). However, you get a "Wrong Region" message in the top left corner of the screen, and there's no playback control. Only the ON/OFF or EJECT buttons from the remote work. It's not ideal but it proves that it technically can play R1 discs so maybe a proper hack will be forthcoming soon.
