I think people are missing the point, if you break a GC disc, you wont be able to play it again, thus having to buy another one. Downloadable content is more like a "safe" way to have a game, If you buy it you'll know you can get it whenever you want, instead of worrying if the disc breaks, gets scratches or something.

That would be cool in the 3D version, like a boss rush mode.

Or use it to quick item usage and checking maps, health and for some puzzles.

loved to see this on the 3DS VC

First game I ever played in my life was Sonic The Hedgehog for the Sega Master System, I was 5 years old and loved all the pretty colors and the dumb RobotnikXD After some time I got a Genesis and got 4 games. The Mega Games collection 1 and Sonic The Hedgehog, and I would sneak out of bed and went to the living room just to play it, at 6:00 AM! My dad would get so annoyed at meXD

The good old times...

That was a bad move, I hate when you get something pre-owned and there isn't a way to delete save data, specially unlocked stuff.
