* Soft Reset for Rumble Menu fixed. New scheme is now used for loading SoftReset.xxxx. Now instead it will look for R4TF.nds (R4TF = 4 character ioType code for DLDI user is currently using with R4TF as an example). If not found it will look for a few specific NDS files to try. If those aren't found it will try boot.nds. If boot.nds isn't found then rumble menu will not be available.
