Hi,

I tried my attempt of a solution to the crazy megaminx earth with combining corners and ended up with
two adjacent 1-faces scrambled, i.e. the cube now looks like a normal megaminx with two sides to solve.
I can easily go on and end with only the top face scrambled. Now, solving this last face by only turning U and R is not as easy as I thought.
The 2-gen algs I found are rather long and similar, so not easy to memorize.
Has someone a good solution to this? The edges are allready oriented, what remains is: orienting the corners, placing corners and edges, as said only by turning U and R.

I tired this since I don't want to set 60 triangles with commutators

Yeah its possible, apart from CP cannot be done with just R and U. are you able to turn the face that is below the F and R faces?
let me list some algs below for CO/EP. (AUF = adjust U face, do U moves basically)
CO:
just use Sune (R U R' U R U3 R')
find an oriented corner and AUF to UFR, if is faces the front, do Sune, if not try a different corner. This will eventually work (its slow but...)
EP:
this does a Uperm in effect, it cycles UF->UL->UR
(R' U' R U') (R U R2' U) (R U' R U') (R' U2)
Again, thats all you need.
CP: if you can turn the face a mentioned above, you can solve CP like this: (Note, this has to be done After EP)
1) AUF so an unpermuted corner is in UFR
2) Do R' D R
3) AUF so the slot that corner need to go in in at UFR
4) Do R' D' R
5) Repeat step 3
6) Repeat from step 2

to give an update here for the algs I use now (thanks to Burgo too):

(top and right are 1-faces and used for the sunes)
3-cycle edges: sune
3-cycle corners: sune U2' sune
turning 2 corners (two mirrored backward sunes or something similar):
(R U2 R' U' R U' R') y2 U2 (L' U2' L U L' U L) U2'
