DsH, it's a different game, of course R1 could work with another game, but with Metal gear it just doesn't sound right.

and if it were put on the R trigger, that leaves the B button, L button, and Z button to replace what R1, R2, L1, and L2 did on Ps2.

While there are still more buttons that need their jobs filled on the NGC's controller, I still think R would work perfectly for shooting which solves one problem :p

Im sure control scheme is something that will be dealt with just fine.

Ahh, finally, MGS on the 'Cube. Now all we need is Final Fantasy remakes and Halo, and we'll be king of the remake console!

LOL......don't forget the King of ports :D
