DupeGod works on all ep4/ep5 based shaiya servers were this kind of duping isn't especially fixed.
(i've never tested it on a ep6 based ps_game.exe server but i'm quite sure, you don't use such a ps_game.exe)
Some game.exe (client side) aren't compatible, perhaps if they forward to the updater (never tried), but in this case you weren't able to start the bot with f6 in the game ;D
If the bot starts with f6, but the item isn't there after alt + f4 and relog (with the client dupegod runs) and you weren't ported to the bootleggery after a try for duping and relog (that's what the server dupefix normally do on a completed duping attempt), you probably did anything wrong in using DupeGod.
Give it a few more tries and keep up accurate with the explanation on page 1
For first time use you may need a few tries until you know how it works exactly ;D
Important:
The client were dupegod NOT runs has to start the trade request and the client were dupegod runs have to trade the item to the client were dupegod does not run (not the other way).
Also important is, that you do NOT trade anything TO the dupegod client while dupegod is started with the client, because of the fact that if dupegod runs, no normal action becomes stored to the database.
For example if you trade an item from the non dupegod client to the client were dupegod is actually running (does not matter if you pressed f6 or not) and then try to dupe this item, it will not function!
I hope i explained it understandable.
So you have to simply know: Before you dupe an item, you have to trade it WITHOUT dupegod running to the clients inventory were you want to use dupegod later. Then restart the game with dupegod and you're be able to start duping.
