I just make a test with your code, and something isn't working fine:
~/brainflayer/brainflayer -v -i int3.txt -o int4.txt
I don't think that line is the right one to get the hash160:
bitcoin@forum:~/brainflayer$ echo "1BTCoinTc7gtcCvYic4KhdUTUqEikBrpVW" > a.txt
bitcoin@forum:~/brainflayer$ ./brainflayer -v -i a.txt -o b.txt
rate: 47.60 p/s found: 0/1 elapsed: 0.021 s
bitcoin@forum:~/brainflayer$ cat b.txt
09da81f1147115816f8ea2b1ccf17ab11c506eda:u:sha256:1BTCoinTc7gtcCvYic4KhdUTUqEikBrpVW
8488984ea64168e341374dbf45e46bd8bf0d007e:c:sha256:1BTCoinTc7gtcCvYic4KhdUTUqEikBrpVW
bitcoin@forum:~/brainflayer$
And on this page we can verify the hash from that address:
https://privatekeys.pw/address/bitcoin/1BTCoinTc7gtcCvYic4KhdUTUqEikBrpVWWhich is: 72a5ed772ca646ff6719c8e2621ad11d34345535
So, to get the Hash 160 you will need to modify those steps, I have some methods to get this hash, but for them first we have to identify the kind of address that we are working with.
