If this has been asked before i am sorry, i checked but could not find anything. I am new to all this and was looking for some advice. I have converted bin/cue to .pbp which when put on to my raspberrypi/retropie PCSX individually work fine but when combined into one file they wont work, is there a size limit in .pbp. files. they file i have is 1.24 gb but will not load, am i missing something. please help one of the older generation out.
