I'm trying dual layer on Smash bros now, will post my results after.
So I've now got an RSBP01 and .ash file, both of which are 0KB.......
I just realized, are you saying that I should do 3GB, extract the contents to my PC and then insert the USB again for another 3GB?
Given enough space, CleanRip will just keep going and put multiple 3GB pieces on your USB drive. You copy them to your PC and combine them using "copy RSPB01.001 + RSPB01.002 + RSPB01.003 RSPB01.iso" (without quotes; thats a Plus-sign between all parts, and the target filename at the end with no Plus in front). Either run that from a cmd.exe prompt or put it into a Batch file (name it "merge.bat" or whatever you like, then run it).
I'm going to do that then, hopefully it will work this time around
I now have the ISO and cutscenes in smash no longer freeze the game. Thanks for the help. ^_^
