Do u have to learn algs for corner twists, or are they like commutators? I usually just use beginner method last step if I get corner twists.

Can cube explorer gen algs for 2x2? Nigel sent me a pdf version of best 2x2 algs doc file, and it has lots of LS inside, but I can't seem to find the case that I just got.

Also for some reason my cube explorer is in QTM. Is there a way to change it into HTM?

I don't know about that, I just use OLL and PLL for my last layer and cancel as many moves as possible. @IsThatA4x4 probably knows all about it though.
@hydynn 2 comms is normally best, because you have 2 chances to cancel moves, and they might overlap; but there are some HTM optimal 2/3-flip algs which are really only worth using when it cancels a lot of moves in your skeleton. As always, you can find it in the FMC document ("bible") thing.

Edit: I'll explain how it works...
Let the twisted corners be "X" and "Y" You're looking for a 3-cycle that will affect those corners + another corner "A". For example, X > Y > A
This creates a normal 3 cycle, which you can solve with a commutator.
If it's a three flip, let's call the third "Z", you would want X > Y > Z for example.

Edit edit: another way, which is just for intuitive solving, only works for 2/4 flips, and is not for FMC as it isn't move efficient, is to:
1. Move the corners onto the same layer
2. Find an alg to flip one corner in place
3. Move the other (or another if 4 twist) corner into its spot
4. Inverse the alg for step 2
5. Undo the setup for step 3
6. Undo the setup for step 1

Here's an example 2-flip:
B2 (R U' R2 F R F') D' (F R' F' R2 U R') D B2

For 4 flip, just keep going until all corners are done, for example:
L' U L R U' R2 F R F' D F R' F' R2 U R' D R U' R2 F R F' D F R' F' R2 U R' D L' U' L
For each set of 2 corners, the twist alg may be different

1. Yes, just blank out the edges and centres
2. There should be a QTM and HTM executable file on your system for CE, choose HTM.

How can I make my own commutators? I've read some stuff about it that you can make your own commutators because it is intuitive? (for exampe 3-style) Also are there any good video tutorials and stuffs on EO and other FMC stuff?

Guys, I'm going to post a bit less and come on the forums a bit less these next few days because of my final exams. I know I said I didn't have them, but three of my kind teachers decided to give us finals. So I'm going to be reviewing a bit I guess, but I'll still come here twice a day or something.

FMC PB2!!!!
Scramble: R' U' F R D2 U2 F D2 R2 F' L2 F' R2 B' R2 D R F2 U B U' B2 D R' U' F

Solution:
B' U' B2 U // 2x2x2
D' F D' F L' // x-cross
D R' B D' B' R // second pair
D' L' D L D2 L D L2 // third pair cancelled into fourth pair
D' L2 B' L' B // fourth pair
L' F' D' F D L // leftie OLL
D' // AUF

35 moves, PB2. Funny thing is I only spent 10 minutes on this solution. I'll do the rest tomorrow, I still have 2 exams tomorrow, but after that, I'm free!
Hopefully I can get a sub-40 avg.
