havent got my r4i gold 3ds rts yet, but I've been preparing with some roms. I have close to 150 (closer to 120, really) and I would guess it takes about 11-12 gigs. I'm also going to have emulators for SNES, NES, and GB/C, so I'll overestimate and say the games/programs are going to take around 14 gigs of my 16 gig card, and the firmware will take up whatever that does. Will having a card that close to the brim pose any problems? Slowdown, crashing, etc?
