Hi there, i'm new here and not too knowledgable about the workings of the site. I have a DS lite and have an R4 card which i use for ebook reading. i've been using ds libris for a year now without a problem, however for the last month everytime i turn the machine off and then on and try to load dslibris it crashes and a 'Guru Meditation Error' come up the the display in red. I then have toformat the card and reload the software back on again, not time consuling but a pain in the arse really. And this week even after doing that sometimes it still comes up with the error. Now i would have thought the card was the problem but i've used different cards and same thing, and the R4 still runs games fine...any help please...don't wannt buy a ereader when i like the little ds one i've been using
