How to use original game on RCPS3 or how to dump them in order to use with RCPS3

Hi,

i would like to try my original ps3 games (all in disk format) on Rcps3. Is it possible? It seems that Rcps3 doesn't support original disk, is that correct?  If so, is it possible to dump my original disk game in "folder format" in order to play them with RCPS3 too? I also bought some DLC installed on my Ps3 for some games: is it possible to extract them from my console and use them in RCPS3 too?

thank you and Happy new year!
