hacking bins with hack3

[zupamleczna]

i have strange problems using hack 3...

1) i found CD001 string in my all 4 bins, when i h*ck them with h*ck3, and then search for CD001 they are also, like before h*cking, is this normal ? shouldnt they "dissappere" ?

2. this is rather stupid question...
what i should write in DOS using hack3 ?

when i write:
hack 1st_read.bin 11702 there apperes someting like "wrong command or filename"

bu when i write:
hack3 1st_read.bin 11702, everything looks like normal; there apperes 3 sets of letters and numbers, someting like this;

0006fa8c->
0006fe5c->
00091678->

right command is "hack" or hack3" ?
