You know the HORI Game Boy Player controllers for the GameCube? They're awesome. Just like an SNES controller. It makes the GameCube my current favorite "modern system" for 2D games.
The problem is, the Xbox has a lot of games that would benefit from a good SNES-like controller. Add to that the fact that my Xbox is modded, it would be great for the shitload of SNES, NES, TG-16, and other 2D games I have on my Xbox's hard drive. With the recent improvements of Zsnexbox, which is basically a port of the PC's ZSNES emulator, I've been craving a good 2D controller. Zsnexbox runs almost every SNES game at 100% speed with graphical filters and all kinds of other shit.
So, back to the question at hand: Are there any good Xbox controllers designed for 2D gaming out there?
