3ds games?

System: Nintendo

im a newer member here who has recently modded their 3DS and Wii. though i heavily appreciate the plethora of titles from Atari to PS2, where is the 3DS roms?
is it simply because you don't have all the roms and only post them when all are found? or is this perhaps a "we can't have too many otherwise nintendo will surely shut us down!" kind of deal?
