What is the most broken piece of video game hacking software you ever used? And what game was it for?

Cheat Engine counts? I bugged everything in Adventure Capitalist

A cheat engine port for ios and cydia. I ended up bricking my phone when i messed up the wrong values.

It was some software for NFS World that almost wiped my PC due to it having a virus. I had to reinstall windows anyway but god damn it was terrible

In 2008 I would use something called Winsock Packet Editor which was seen as malware by most antivirus engines.
