I bought an used PS3 OFW 3.55 with Multiman 2.06 (or sth like that). AFAIK, I can only play games that are compatible with OFW3.55 or have been fixed to work with it. But -as example- how can I play games that requiere highter OFW? And how can I fix my games to work with it? Also, is it recommendable to update Multiman trough it's update menu? O I should uninstall it and install a CFW? I don't really know how all this work... Thanks in advance!
