I`m looking for a multi-region hack for this player.

It`s assumed there are no hacks for this player which is untrue. :)

When i asked a retailer about buying one (open) he produced a remote to hack it.
I didn`t see the remote not the code used. :(

Just tried a similar hack from other postings.
The menus appear as below but the hack does not work using either 2812(0) or 12450.

ANY IDEAS PLEASE?
come on you Sony people :x

Switch DVD to Stby
Press on R/C 'TOP MENU' - 'CLEAR' - 'POWER'
A menu appears - 'Remcon Diagnosis Menu'
Choose Option 2 and then Option 4
Enter with R/C '1 2 4 5 0' and press Enter
0 0 0 0 0 appears press 'Enter' and switch to Stby
