I have an original R4, have had it for years. Played it for awhile on my old DS phat, and then eventually upgraded to the DSLite Super Mario Special edition. Over the past year I have had a lot of issues with freezing. It happens mid game play, and also seems very likely to occur when the taking the DS out of sleep mode. It happens in all games, and in emulators as well. I had not been playing the DS a ton so it wasn't a major issue, but now I seem to be playing it more often and it is incredibly annoying and frustrating. I don't ever remember this happening on the original DS. Could it be a sign of wearing out, or is it possible it is related to the DSL itself? Unfortunately I do not have another DS to test the cart on, or another cart to test on the DS. I have heard/read about the cardboard trick, but that seems to be mentioned almost exclusively with other carts like the Acecard. Thoughts? Suggestions?
