NES games I think you should be able to fit close to 100 in the memory.... but the number of channels is limited so your total will be 48 minus whatever main channels you have (Disc, Mii, photo, forcast, news and shop are obligatory) so 42 maximum.
SNES games are on average double the size (in blocks) so you should still be able to fill all 42 channels with SNES games.
