does 4 g wrok on r4

ok i have a 2 g micro sd sankist card i am thinking of going to a 4 g and i like to know will the 4g work as good as a 2 g sandisk. i rember reading some where that some one said that it made the roms run slow on the r4 so is this a good idea or a bad one

If you have a genuine R4, any microSD card labelled "SDHC" will not work. There are non-SDHC 4GB cards, but these are typically rare and unreliable.If you have an R4 clone that supports SDHC, then go right ahead and upgrade.

well i get it then and see if it works becaues they type of mirco i am use is what looks like a normal sd mirco card so if the 2g is the same and i format it the same way as i did my 2g then there sould be no proplems at with it then right

Replying to #3

Wrong. SDHC cards will not work at all on a genuine R4, regardless of what you do with it.

well then how do i tell if it is a mirco sdch card then

It should say so on the card itself.Like I said though, it's highly unlikely that you'll find a non-SDHC 4GB card. If you have a genuine R4, you should just stick with your 2GB card.
