I'm afraid I have to complain a bit.
1) No crosshair.
The reason GE64 worked without a crosshair was the fact that the game used some quite powerful autoaim. You should either throw in autoaim, or make an autoaim feature, or at very least make a toggle feature on the crosshairmode that allready exists.
2) Start with weapons.
One of the things that made Goldeneye 64 fun was the constant search for weapons, and that all weapons were used. The way it is now is that players get like five different guns at the beginning, each with huge ammounts of ammo, resulting in some players getting big advantages.
3) The list
The bad thing here is also that you have to go through the entire list of weapons. Make an immediate switch, like it was in the N64 classic.
