r4ds administrator?

dos r4ds need administrator rights to put the roms on it from the computer? because i dont want to buy it if it isent going to work.

No, it doesn't. You just copy the ROM file across to the SD micro card as if you were copying a word document to a memory stick.

All setup for the R4DS is drag and drop, unless you have to format the microSD card to FAT32 or whatever.
