Problem with yugioh 5ds stardust acceralator

A few days ago i was playing an online game.
I had 8000 points and had a monster with 1500 attack enough to make me win by attacking him directly.His field was empty.
Suddenly it said you lose!
i tried to find the guy again ,i found him and before i even draw it said you lose again,without showing any exodia or anything.
HELP ME !
What am i doing wrong?

 

He Must've been using Action Replay for instant win.

 

I was told auto-win cheats don't work online, but I haven't played online so I haven't confirmed it. It -does- sound remarkably like the auto-win cheat though.

 

that would seem the case

 

that means it works on online games?
oh my god!

 

cheats work on all games even online and rom use but sometimes cheats can also disconnect games from wifi network

 

i once tried using an instant win cheat for fun, but instead of his life points going to zero mine did!!!, but that was only on online play

 

your best bet is to just play with people you know. :/ thats why we have friend codes.

 

i am a real player if anyone wants to battle
