Logic Masters Deutschland e.V.

I made this puzzle a few years back, but never got around to testing it. I always found empty grid puzzles very interesting, so hopefully others will enjoy this one too. It can 100% be worked out through logic (and just a bit of basic arithmetic). This is my first puzzle, and I don't play a lot of complex puzzles myself, so I don't really know the difficulty level so I'm sorry if I over or under rate it. Hopefully someone can point me in the right direction.
Rules:
Normal Sudoku rules apply.
Exactly one pair of sixes are adjacent diagonally, and are connected to no other sixes in any other way.
Every other 6 is a knights move away from at least one other 6.
There are 2 marked magic squares on the board.

A magic square is a 3x3 region on the board that contains exactly the digits 1-9. The digits along each row, column, and diagonal of the square all add up to the same number.

The cells on the arrow marked diagonals add up to the number by the arrow, and the values of each cell are of the same parity (that is, they are all even or odd).
On the blue marked diagonals, every value appears at least 2 times along it.
No other numbers have any other constraints.
