yep, the whole work was done by tpruvot, djm, tsiv and others, alexis78 forked or palginmod based of this fork are ok. They are fast and free as original ccminer. For some fckd up reason that SP dude decided that he can take others huge work, change it a tiny bit to add 5-10% hashrate and sell it as a private miner while not paying 95% of his earnings to the original developers. This is outrageous, i hope sp will get a huge d*k in the a for this.
