Godzilla ps3 help

I got the first release of this game, but I need to say I never had a Playstation system. I had been looking for an old console compatible with PS2 games in order to play War of Monsters too; but I just saw what shows the case of Godzilla game: Region 2. The used systems here show region 4 and therefor the game is not playable. Is there a way to alter the region of the PS3 system? or Are there new consoles with region free format? I remember from the very first instance about the game that it was "Region free"

Any help will be appreciated-
