DSTT, M3 and other R4 Alternatives
There are lots of alternatives to the R4 Revolution. They all really do pretty much the same thing – act as an adaptor for the Nintendo DS or DSi to read from and write to SD cards.
The question is which one should you buy. The most well known is the R4 Revolution. As I’ve mentioned plenty of times on this site, it has a massive identity crisis, with a huge amount of imitations, some with similar and some with exactly the same name. On top of that there are different variations of R4s from the companies that emerged out of the original R4 Revolution team. Because the original company has split up, there are no more official updates of the firmware. You can however get unofficial firmware updates.
The M3 has appears very similar and the software it runs is also very similar (so similar that R4 Revolution and can older editions of the M3 firmware). As with the R4, the latest edition of the firmware for the M3 was created in early 2008.
There are a host of other cards including the DSTT, AceKard, CycloDS. Each has their supporters but there seems to be no easy answer to the question of which is best. At the end of the day they pretty much do the same job and all work reasonably well if you get a good quality unit.
