Cartridges termed Nintendo DS cards and also newer acekard 2i cards were first made to let users associated with those Nintendo handheld consoles play and not games, but music and movies anyway. A number of newer DS cards carry option to play a myriad of homebrew software as well as have the capacity to read PDFs and eBooks. The DSTT was among the first cards ever to be produced in the Nintendo DS and DS Lite, and hence was highly sought after. It was totally free card to ever be produced behind the famous R4 card, otherwise better-known as the R4v2 or the R4-0815. The DSTT was the 1st ever r4 to utilise the «games-menu» system in its program. Compared to making the operator select from three options at a startup menu screen, the DSTT card would simply display a listing of all the multimedia files and games right away upon loading. This gave users the wherewithall to quickly and effectively select the things they had to play on their Nintendo ds lite console. That technique are less good for advanced users who may wish to use their DS for other uses say Game Boy Advance emulator and so, but great for basic users or gaming enthusiasts who participate in the same sorts of games (or media) regularly. The DSTT has well-known dimensional control, that's slightly lighter when compared to original R4 card. Failure rates on the DSTT can be extremely low as shown in the review conducted by GBATemp in 2007 if the DSTT was first released. For example the R4 card, the DSTT initially used a spring mechanismi to keep the r4i gold in the console, but after a couple of months if ever the manufacturers realised this increased the failure rates with the cards, they begun to choose to push-slot instead, which worked rather effectively because there has been fewer mechanical components on the card which will fail. As becoming Nintendo DSi and DSi XL consoles were released, the DSTT team has released a sister card called the DSTTi which is that will work with the newer Nintendo consoles still. Which means that, the DSTT still enjoys firmware support even today as it can accept the same firmware that your DSTTi uses.
