Creating delay for p2p games

Hi! I was wondering what you need to do to make your opponent get delay in a p2p match like fighting games? Can anyone tell me where to look? thanks!

Do you mean psp? I mean the android application

This is an interesting concept it would be really funny to see this in action

You could use a program like Wireshark and sniff dem packets for the user's IP, from there you can send a large amount of packets to the user's IP, enough to create lag, but not enough to boot them offline.

it would be funny watching opponent get lag,especially with high-ranking opponent
