The offline boost time and research level cheats worked for me on chrome as well. I assume the research points cheat does as well, but I can't verify - mine were in the billions by the time I attempted it.

WORD OF WARNING:
I also got carried away and tried hacking the particle levels and city rating (4bx1, both), on chrome and firefox respectively, but both caused the game to crash. Now, it goes through the loading sequence on chrome, but goes black and causes the page/scrollbar to freeze; it does the same on firefox, but instead of freezing it slows the page down (apparently)/I can still use the scrollbar.
And now I don't know how to fix it, and I was really getting into the game, too.

The same kind of thing happened for me and now I am stuck playing it on internet explorer.
