I will explain more about Sine below.
STAGES:
take a look at http://www.elecbyte.com/mugendocs/bgs.html (http://www.elecbyte.com/mugendocs/bgs.html) for more info about stages
[BG mirror]
type = normal
spriteno = 6,0
start = 0, -142
delta = 0.7,0.9
layerno = 0
mask = 1
sin.y = -8, 240
Let me explain the trigger:
sin.y = -8, 240
- Sin is senoide curve
(http://upload.wikimedia.org/wikipedia/commons/thumb/b/b2/Sin.svg/400px-Sin.svg.png)
http://en.wikipedia.org/wiki/Sine_wave (http://en.wikipedia.org/wiki/Sine_wave)
- sin.y means that we are going to have the effect just on the y axis (vertical). For horizontal movement, use sin.x (*)
- -8 is how much the element will move (keep in mind that we are talking about a Senoide, so it will move the amount*2 = 16 (-8 and 8).
- 240 is the total time of a whole curve (the up and the down anim).
Some images to illustrate the effect:

(*) on Mugen 1.0 this parameter is basically superseded by the SinX background controller.
Look at http://www.elecbyte.com/mugendocs/bgs.html#background-controllers (http://www.elecbyte.com/mugendocs/bgs.html#background-controllers)
CHARS:
On chars, its a bit more complex.
From SodonHID's codes:
Quote
[State xxx, x]
type = VelSet
trigger1 = 1
X = 3*sin(time/4.0) ; ** Originally, it was (time/4)
Y = 3*cos(time/4.0); ** Originally, it was (time/4)
4 is the frequency (the "speed"). 3 is the range (or amplitude, diameter)
** Using Bia words:
It may seem ridiculous, but time/4 will never bring a fractional result (5 / 4 = 1 for mugen). While time/4.0 results in a fractional number.
To summarize:
value / integer = integer division (without fraction). The result is an integer
value / actual value (eg 1.0) = split real (fraction). The result is a real number.
By ChonWang:
Just to help:
x = sin (time * A) * B
y = cos (time * A) * B
. The lower | A | and | B |, spins more slowly
. The lower | A | or higher | B |, the larger the radius
Notes:
- Signal (A × B) indicates the direction: counterclockwise (+), clockwise (-)
- The addition of VelAdd creates a helix
- | x | x is the module, ie the absolute value of x.
hope that is helps.

I wonder, is there a way for a projectile to have the same (or at least similar) physics to the fire balls in Super Mario? I was thinking they would constantly use gravity to move down, but when it gets near the floor, it jumps up a short bit (with a velset) and it continues like this.

Make a helper with this
[state 0,0]
Type = VelAdd
Trigger1 = 1
y=0.25
Its so simple:
Make a helper with this
[state 0,0]
Type = VelSet
Trigger1 = Pos Y>=0
y=-6
Change the -6 to make it bounce more.
