Updating public folder takes 90 cpu
If you've been running into problems with this you can probably verify it by searching for *on your hard disk and finding duplicates.
There is supposed to be some code to handle that case, but I guess it is not working well.
We put these at the top, hoping that it will cover 90% of questions and cut down noise in the forum.   For extra credit, contemplate why this might have changed. Don't waste time asking, it will only make us angry. If a game really doesn't work, no matter what you try, you can submit a bug report for the game. If you are running De Smu ME on a laptop, then a laptop cooler might help.
If you can't make it work, then give up and go buy the cart. If you create new threads in our forum about these games, don't be surprised if they get closed or deleted depending on how obnoxious they are. Uncheck display input De Smu ME is a very CPU demanding app.
Older versions would use the rom directory; and now in Windows it is the directory that the emulator runs from; and in OSX/Linux it is ~/.config/desmume.
In Windows, use the path configuration to point to wherever your files are or copy them to the new spot.
