btw y does like half of the games on my r4 dont even load they freeze when i click on them
only like the new ones r working it also wont let me read my mirco sd card when i put it into the reader
what should i do?

Use another adapter/reader. Also, the 'Cannot read game card/savefile' error is not related to dust. Find how out to fix it in the Common Issues linked above.For freezing, backup all your files and reformat your MicroSD.
