I solved bles ver stuck on loading problem. In bles ver there r 3 folders DLC, EBOOT 4.xx fix , Metal gear solid. U have to convert the game and before making pkg copy all SPRX Files located in Metal gear solid folder USRDIR/master/prx. And paste to the NPEL BLES folder and make pkg then resign them and install on your han ps3.
When you open the game it install the gamedata and autosave then it stucks on loading. So you have do is. Go to gamedata utility and delete the metal gear solid gamedata and go back on metal gear solid press and check for update and it will show you latest update go ahead and install it. And the game will work fine.
