I personally never used that method with cable...
make like this its a bit harder u will need some time to get it right but when u get it 1k stones wont be a problem
1st. Run ur game, my advice is 2 clients (if possible on this al)
2nd.open ur Internet browser type youtube, open 10 tabs with vid
s, open lime wire + bittorrent or something = u download a LOT of stuff.
3rd.lets say u already prepare stuff u want to duplicate, and letters and so on, so actually 3rd part will be wait a bit till lagg actually starts. (run in town from one point to other with open (U) mail system. When u see ur char stopped for a few sec, fast press send few times.
4th. switch to another char, repeat the running stuff (from one point to other), when lag take his place, fast open all letters (OPEN> safe) and when u open save all mails just press SPACE and hold. If lag was good, u will get duped stuff after several (depends on how much u save) notices SPACE will remove em
5th. stack em with already dropped stones or bought or something
6th. store em or just use.
TIPS for gold:
if u wanna fast gold, dupe can help and no one will ever know are u a duper.Make 5 gold coins and just dupe em. When u dupe em, 1st one (stack of 5gc) leave it, rest sell to merchant (50M each) so u can sell 4 only then store 200M in storage. and repeat the procces u will get Bils in matter of minutes
