In a bid to be transparent and open I thought I'd post my findings regarding the DSTWO. First off a bit of background info. If you didn't already know from my signature I've been reviewing DS/DSi cart for some time. My web site two-screens.com currently has 19 reviews in total. I've been involved in the GB/GBA/DS since the days of bung carts. I received my DSTWO package on Monday. Due to time pressure from work(installing new server/client system) I only had chance to do a quick test of the GBA emulator. During this test I had a few random lock up and freezes. At first I put this down to the "beta" nature of the OS. But as time progressed every time I rebooted, my DSi was having trouble detecting the DSTWO. Now it doesn't detect it at all. I have tried all the usual procedures, cleaning the contacts, cleaning the DSi slot 1, reformatting the memory card and even the old paper trick. Lets put this into context. I have 7 other DSi compatible carts. I retested them in order to clear up that this wasn't an issue with the console its self. they all functions as expected. Even the crappy £4 R4i Gold. On closer inspection of the DSTWO, I found it to be a poor cousin of the DSONEi in terms of build quality. The very first time I inserted the cart into the DSi there was a noticeable creak. The DSTWO fits into the slot1 very tightly , almost too tight. The IC chips on the label side are quite prominent. I'm saddened by this hardware failure as Its the first time its happened since I've been reviewing carts. I was hyped to finally have the DSTWO in my hands and could get on with testing all its features. During the lead up to the DSTWO release I can recall some forum messages,saying that the Supercard team went through a few early fab runs due to hardware problems. I hope these haven't made to final retail revision. It wouldn't be a good start for the product in terms of buyer confidence. DSTWO is a premium product and therefore its build quality should reflect that. The iEDEG cart currently blows it away in terms of build quality yet it is considerably cheaper. Perhaps I have been unlucky and just got a random dud. I used DHL in order to receive my cart fast. I'm probably one of the first adopters of the cart in the UK. It will be interested to see what happens when the flood of pre-orders start arriving at buyers addresses all over the world. If there is a significant percentage of failures I'm sure the GBATEMP community will make it known. I have contacted both SHOPTEMP and the Supercard team regarding this hardware failure. They have yet to respond. This will be an acid test of both parties customer support. I will keep the community informed of any further developments.
