You can get the miner from the top of the tread.  You need the roulettecoin-qt.exe running locally on a computer.

for windows create file  in %AppData%\Roaming\Roulettecoin\roulettecoin.conf

with the following content

rpcuser=ANY
rpcpassword=any
rpcport=8668
rpcallowip=*
daemon=1
server=1
listen=1
gen=0


To mine with the custom miner running on same computer as wallet.

minerd.exe -o 127.0.0.1:8668 -u ANY -p any -t 6

use the -t to set your thread count.

if it works you'll see
