An completely empty one? No subfolders? Could you please delete this folder again, then enable sd card logging in wiiflow.ini and post it here?
Since I updated to r506 there is a wiiflow folder created on the root of my sd card (as far as I can tell its created on boot) which contains no other folders or files.
I assumed this is the default location for settings covers etc. Its created even though wiiflow paths are set to another location. It doesn't seem to be needed/used.
I will post the log/info you need as soon as possible.
Also re: the video settings I hope you don't mind me asking,
Can "system" option be changed instead to "System menu"?
And "default" could be replaced with a "global" setting for the individual games ("global" or "System menu [global]" or "global [System menu]" etc)
Then we just have the essential in global video setting, "System menu", "PAL 50", "PAL 60", "NTSC", "Progressive", "Auto-patch" and then in the individual game config the "global [***********]" too. Just if ever possible.
The "system" option does use the setting from system menu is that right?
What exactly does the auto-patch setting do? And what is the difference between this and the game region patch/settings etc?
