Some of the features of R4 is that it can make use of any micro SD flash memory card and is capable of supporting cards with memory capacities for up to 4 Gigabytes. Many experts though recommend using the 2Gigabyte version for an optimum gaming experience, but you can make exceptions if you want to do various other things such as storing music, movies or other software applications. These are the cases where you should use a 4 GB card otherwise 2GB is enough for your purposes.
