- Fixed Nand Emulation from SD-card. - Fixed "CheckSave" functions. - Fixed feature to flash a save file from emulated NAND back to real NAND. - Some minor code cleanups and bug fixes. neek2o: (neek2o r93+ only) - Fixed return to channel function for titles on emulated NAND - Added an option in wiiflow.ini: launchwiiflow in "NEEK2O" domain If this option is set to "no" the "exit to" option in home menu will launch neek2o SM instead of the "DWFA" channel. - If the return to channel option is set.. neek2o will return to that specific title if that title exists on the emulated nand, even if the title was launched from real NAND.
