Coins and boosters can be changed. Memory Range is Anonymous and value type is Dword X4
For boosters it's easier to find if you have at least 3 of them to start with.
If you have 3 then you would search 3X4. Then use one and refine 2X4. Use another and refine 1X4.
You should only have a few results left now. One will most likely be a very big number. Edit that to the amount you want and add the X4. So if you want 9999 then you edit 9999X4.
It's the same procedure for coins. Search the amount you have with X4 after it. Use some, refine new amount with X4 and so on until you'll probably end up with one large value and edit that in the same way.
