scramble:
B2 F2 R2 F2 D' U' B2 U R2 B2 U' F' R2 D L2 U L B2 F
In the "solve cross" window it says:
D(ec): F' R U L2
U(ec): z2 D2 F B' D F' R'
L(ec): z' D F R B' R2 L
R(ec): z L2 U R' F D
F(ec): x' D F2 U2 B2 R
B(ec): x F D' F' B' R
If you copy the scramble into alg.cubing.net, and let's take the 2nd one: z2 D2 F B' D F' R'
you can see that it solves the white cross (white was originally Up)
If I click on R(ec), now it says:
D(ec): F' R U L2
U(ec): z2 D2 F B' D F' R'
L(ec): z' D F R B' R2 L
R(ec): z F U' L F' R' D F'
F(ec): x' D F2 U2 B2 R
B(ec): x F D' F' B' R
so this means that z F U' L F' R' D F' is a solution for extended cross on red, which was originally on the R side.
Crosses are all solved on Down. Yeah, so that's it.
