I had bought one of those broken(qkin) ds-x cards, but returned it today with an RMA to modchipstore.com. They made a happy customer out of me by taking that piece of crap back. Thanks to this forum, I managed to find out that R4 kicks the ever living crap out of DS-X. I felt so mislead by their false promises of firmware updates and fixes. I visit there every once in a while to see if they solved the issue, but it is still ongoing. Now to my initial reason for this post: i feel real bad for those that are sticking out over there at DS-X. It is a losing battle. R4/M3 now rule the slot 1 market. Why do they even bother at this time? Shouldn't they just pack up shop and tell everyone to go home? I know I sound a bit smug, but I am sure I am not the only one feeling this way at this time.
