guys! need help with burning image files such as ISO, BIN/CUE to cd to be played in Playstation.

here's my prob... i downloaded some PS Games containing : img, ccd and sub files. I used Magic ISO to convert the img file to ISO, afterwards i burned the image using Nero 6 then played it in my playstation console but nothing happened or the game didn't load. After the failed attempt i converted the img to BIN/CUE files. After the conversion the CUE initially contained the whole path i.e. "D:\game\name\xxx.bin"; but i changed the file name found inside the CUE file to "name of game.bin" ; then burned it with Nero and played it in my playstation but still the game didn't load.

Can anybody help me with this prob? what must i do? how do i make them playable in my playstation?
do i need to use another application?
