I recently received what appears to be the latest incarnation of the R4DS slot-one card. It was purchased from amazon.com (I needed one fast) for a friend. Initial differences are as follows: - firmware is different. they are now using a different encrypted firmware which is currently at 1.16 (english version). Firmwares are not compatible between this version and the older R4's - the case has gone back to using a spring loaded micro ds slot - this new version supposedly supports SDHC memory cards up to 4gb in size (however, I don't have one on-hand to test out) - the chip on the pc board is larger, requiring a hole cut into the top half of the shell (underneath the sticker). additionally, a holographic sticker on the back of the cart marked as "2008" covers the screw to separate the halves of the shell. - the vanes between the contacts are back. - they have a new website (click here) for the new firmware I'll take some pictures tonight and post them.
