Do NOT repost cheats from cheatslips. These cheats are:
1.) From inexperienced hackers
2.) Are untested outside the initial creation
3.) Are on a site known for stealing credit for codes, and
4.) Most of the time do not work
Cheats found here are authentic, and are guaranteed to work 99% of the time, and are more thoroughly tested. If the only source you can find is cheatslips, chances are the code doesn't work. Any hacker worth their salt will post their cheat in more than 1 place if they can find more than 1 'trusted' source.
@TomSwitch knows cheats posted here get stolen, and thus doesn't post the actual cheats here, for example.
