Hello,
probably many of you already known this, but it could be useful for some beginners.
How to get HP-Address with cheatengine.

The trick is to search for values between 1327400000 (d) and 1327410000 (d).
You will just get few addresses, change their value to see which it is.
If you dont get all values, you could increase the interval.
Ofc. you will also get the XOR address.

HP-value is calculated = HP-address XOR theXORaddress.
You also get the some other addresses calculated by XOR-ing.

Thats all.
