If this is still a thing, I pride myself on being a game breaker. I have recording software so I can record every play session for analysis and if a bug arises, I will do everything in my power to figure out how to replicate it. I've found bugs in many released games, some already discovered, but two I do proudly have credit for on Gamefaqs https://www.gamefaqs.com/ps2/197042-dark-cloud/cheats https://www.gamefaqs.com/ps2/561482-the-sims/cheats
There are many more, but Gamefaqs refuses to publish them due to not being "useful", such as a method to defeat Xelpherpolis in the early half of the game Ephemeral Fantasia for the PS2 in one of those "You lose no matter what" fights. You can win, but you get nothing for it and it carries on like you lost anyways.
I also have the luck of the damned, so if there is a game breaking bug out there, I'll find it https://www.youtube.com/watch?v=w9jB8DOlHNA https://www.youtube.com/watch?v=wZ14QNK_zvg
