This is Lostcoins and fialka forked of Rotor-cuda:
Lostcoins-mainhttps://filetransfer.fr/download.php?file=2N4HS16CPM
Fialka-mainhttps://filetransfer.fr/download.php?file=IV153TFKUZ
I compared Readme of Rotor-cuda and fialka the options are the same.
I downloaded them on github but scan them for more security,they contain the executables for me they are safe .
Some people on reddit try to sale them don't buy!
Good Luck!And happy Hunting!!

phrutis has closed all its github directories if anyone is interested, I have Fialka, Lostcoins fork of Rotor-cuda.

thank you this one seems different to me but I understand and I can continue the hope makes live!

Hi I have been interested in the puzzle for several months and after months of scanning and learning I found a site that seems to have scanned all the range' in #64 puzzle's keyspace (from 2^63 till 2^64-1 decimal, 0x8000 0000 0000 0000 - 0xFFFF FFFF FFFF FFFF) and he find nothing.https://hashkeys.club/64/.
How is possible? Sorry for google translate.
 Can someone explain to me!
