Alright, back to post 33, the position is indeed impossible to attain, both the rooks on a8 and h1 has to be sacrified to obtain that weird arrangement of pawns. But this position CAN be possible:
possible or impossible?
Sort:
Follow-up As Jamie pointed out the remainigs Rooks come indeed from promotion, as all the pieces and a pair of pawns has to be cleared to reach the position. I will try to post later a exemple but since this a retrograde analysis it's quite a pain.

Well, how about this? Could this position even be reached from a legal way?
Sure.
Not the most efficient way, but I reached the position.
Ugh... How do you like that? Not even capable to answer properly for his own puzzles... Like the heck, man?
Great skills for solving this DavidMertz1. Well done!
#38 is impossible. If the knight was discovering the rook that means it had to be on c1 or e1. If it was there, then the bishop was giving check! :)

Nope because the check was blocked by a black piece that the knight captured.
i made this one too
you're right Scottrf i will try to make a more difficult one
i'm running out of ideas but i was managed to make this one
really nobody?
Possible, but it's stalemate.
White king moved to h1 from g2 and black pushed h3.
you're right again Scottrf!
it's again been a long time and i can't make hard puzzles and i wanted to give it another try but my puzzles were getting too simple but i just want to post this one so...
really nobody?
Impossible. How could White could castle Queenside since the b and d pawns are on theirs initial squares? This means the Bishop on c1 was purposely discarded to allow 0-0-0, thus impossible.
wrong... 
i'm sorry but your answer or your explanation is wrong (I'm not telling which one)
you're both right.
Nc1 took a piece on d3 which mated the opponent
