Cheat Engine

[1kk10]

Hi all..

My name ikkio and this is my new post..
I am using CE v6.1 and so far it help my experiments for some games, until I've got problem for some game for PC, such as Let's Play Pet Hospitals - Deep silver and FunPark Beach Blast.
The problem are, CE v6.1 always give 0(zero) results for the money/credits from the games. I tried all the ways that CE tutorials, but the results are 0 or game crash. I tried with text too, and it works for text. But, when I restart the game, it back to the original value.
So, my questions are:
1). What is the correct of value type for the games (Let's Play Pet Hospitals - Deep silver and FunPark Beach Blast) to check the money value?I tried all types and only text is working for the games.
2). When I tried with text, and I used "find what writes to this address" option, I got opcode movzx eax,byte ptr [esi]. And, I tried the hex with first scan in CE. The result is none (the way is same as the tutorial - pointer). Can some one explain to me, what is the meaning movzx eax,byte ptr [esi]?
3). Why is CE v6.1 not working the games? is it because the different game engine or...?
4). Is there a better way to hack the games?From script file, maybe..

I am not a programmer, but I likes to script an application programme if there is an option to customize it. Thank you for the advices or suggestion all.
