PSX games save data. PKG or BIN?

Hi everyone,

Basically have over 100 PSX games and transferred them to PS3 in BIN format but if it's multi disc games I have to mess about going into file manager in multiman to change game save name so it loads up properly.

Would converting them to PKG files make them run better without changing file names for save data? Or can I use my BIN files but make multi disc games work easier?

Thanks
