I think there's R U F B' R2 F' B U R' and R U R U R2 U' R' U' R' U2 for the first one.

Those are good, but it will be even better if I can find something that would also work on a 5x5

Hello fellows. Can someone help me to find convinient algs for those edges cases (and their inverses):
UF->BR->UB
UF->RB->UB
UF->FR->UB
UF->RF->UB

Also, I could do it using cube explorer but I can't find where to download it now. Can you help me there as well? Please

The cube explorer page goes down a lot; I don't know where you can download it atm.

When you say something that works for 5x5, do you mean wings or the other edges that are equivalent to 3x3 edges? Does it have to be supercube safe?
for example, R d' M' U2 M U' F' y' works for the first case for the not-wings, but I don't think it's supercube safe.

I can view the page fine, I haven't tried downloading it though since I already have CE.

The webpage isn't available for me, and I remember it not being available for a long time between me finding out about it, and me being able to actually download it. It's a bit unreliable...

Okay, I found what I was looking for by myself. CubeExplorer isn't a very good thing to find algs that are very convinient to execute, as long as you aren't patient enough to look through the list of tens of trash algorithms for each case.
Earlier I used this:
UF->BR->UB z x [U M' U', R2] and z x [U r U', R2] for wings
UF->RB->UB z x [U' M2 U, R2] and r2 instead of M2 for wings
UF->FR->UB z' x' [U' M' U, L2], r instead of M for wings
UF->RF->UB z' x' [U M2 U', L2] (for its symmetrical), r2 for wings

After a while of consideration and asking other people for it:

UF->BR->UB R D' [M, U2] D R' for 3x3, [Rw U' [R2, U' r' U]] for 5x5 and [Rw U [L, U r' U']] for its symmetrical 5x5 case
UF->RB->UB [R; [M' D M, U2]] and [Rw; [D, r' U2 r]]. There's impossible to make a cancellation for its inversed case in 5x5, however [L' [r D' r', U2]] is faster than the old one.
UF->FR->UB R' D' [M, U2] D R for 3x3 and still z x [U r U', R2]. I timed average time of this alg execution and compared it with others (like x' l [l U2 l' D] l' x). The average time seems to be faster with the old alg.
UF->RF->UB Rw' D' M' U2 M D M' U2 R for 3x3, still [z x' [R2, U r2 R'] for 5x5 and [L; [l D l', U2]] for 5x5 inversed case

Also, nice wings U-perm: Rw U' R' U' r' U R U' r U2 Rw'

You can get pretty good at eye-balling whether or not an alg is reasonable, that said I'm still not great with it.

I plugged this into my 5x5x5 solver and found some shorter algs for you. These are all single slice turn metric 10-turn results, even though the scramble made use of your wide moves.

You've probably looked at it hundreds of times, but I doubt many people find it easy to read off algs from that image.

I need an algorithm to solve the edge parity on my 3x3 void cube. I need to switch the two remaining corner pieces because they are permutated incorrectly. I have all the other edge pieces solved and the two other corners solved. I tried to upload a picture but by the time it was sized small enough to fit it was impossible to see. Thanks again.

Look it up. It's because the imaginary centers are wrong.

An interesting 2gen sequence (ignore the centers):
M U' M' U M' U M' U' M

A variation which only affects the E centers:
M U' M' U M' u M' u' M

And finally, a void parity:
M U' M' U M' U M' U' R U R' U' M U R U' R'

Sorry for the noob question but is there a way to get only the top front edge and the bottom front edge to stay where they are but flip the colors. The cube is solved except for those two edges. They are in the right spots just the colors are backwards

x ((M' U)3 M') U2 ((M' U)3 M') x'. There are shorter and faster, but this one is okay and is the easiest to remember I think. The first and last sequence of moves is the same.
