Do you play with the game boy and game boy color borders? Do you think it gets too small then?

Wait, you can use borders? As in "Super Game Boy" borders?

@abgar - If you hold down start/select while loading a VC GB game (like original resolution for DS games), the top screen will emulate the look of the original Game Boy, and you can use the depth slider to "sink" the screen within the top screen for a more authentic feel. Sadly, the Super Game Boy color mapping and borders are not available to to this. Perhaps as a future system update (and, if so, with a small upgrade charge) will allow this, but as for right now, nope.

but it's so nice! although a little bit small? Don't anybody have an opinion on this?

It's pretty cool, but whether I use it will probably depend on what mood I'm in, just like whether I'll play the GB games in B&W or old-school green.
The 3D effect that makes the image look like it's behind the screen is a nice touch though, and I look forward to trying it out with games from other systems too. Perhaps they should simulate the short battery life of the Game Gear somehow too...oh wait, the 3DS battery life is already short!

Hah, at least we don't have to worry about going threw 6 AA batteries every 3 hours, that was brutal.

Actually, when the 3DS battery is low, the light on the game boy border dims.

@yoyogamer: LOL

I'd love to see an update where Link's Awakening and Donkey Kong can have their SGB borders.
