If anyone is still wondering how to use artmoney to cheat with Authority or anything else, I found a simple solution, we'll use Authority for this since it's what I used:
1st: Search for the Value number (in this case, the total Authority)
2nd: Once all the float 4s appear(To make Float 4s, click search, the browse button[the 3 dots] and then select Float 4 bytes. After selecting that, select at the bottom, above ok, multiples of 4) Hit the Add All button (blue arrow) once that is done, click the top/bottom most value then ctrl-left click the vice versa bottom/top most value.
3rd: Right click and hit Select Value, once that appears, add the number you want and hit okay. They will all become that number and when you look at your game, you too have that number.
This board hasn't been updated since last year, but I thought I'd give this tip to anyone still playing or looking for an easy way. Especially if you want to try this with any other game.
