 ==Instructions that access the memory==
 Start Cheat Engine and the game. Attach Cheat Engine to the game using the Process List dialog (File – Open Process – Open). Skip the prologue and start the game from the beginning then save the game immediately. Now click once to go to the next text. The screen will look like this:
-[[File:AGTH Mite1.png|Figure 1: Second game screen after the beginning.]]
+[[Image:AGTH Mite1.png|640px|left|thumb|Figure 1: Second game screen after the beginning.]]
 The text will be “ドアの脇に鞄を置いて、そのままキッチンへ向かう。”.
 Choose “String” as value type and press “First scan”. Cheat Engine will find two addresses.

+[[Image:AGTH_Ce4.png|640px|left|thumb|Figure 2: Cheat Engine's main window after searching for “ドアの脇に鞄を置いて、そのままキッチンへ向かう。”.]]
 Double click both addresses to add them to address list. Now click in the game window. The text will change and with it the text at the address 4422F8 will change too. This is the address where the game is writing the new text. You can delete the other address, we don't need it.
 Right click the address 4422F8 in the address list and choose “Find out what accesses this address”. Cheat Engine will now set a breakpoint at this address and find all instructions (called opcodes) that access this address. A new window will open. Click once in the game window and a list of commands will appear in the new window.

+[[Image:AGTH Opcodes2.png|left|thumb|Figure 3: Instructions that access 004422F8.]]
 The window shows all assembler instructions, that access the address 4422F8. Click “Stop” to stop looking for instructions that access the address. Now we have to check the instructions one by one to find the right one.

 We will start with the instruction “0040FAAD - C6 00 00 - mov byte ptr [eax],00”. Select it and click on “Show in disassembler”. We have to set a breakpoint at the instruction at the address 40FAAD. Press F5 to set the breakpoint. Now click in the game window and Cheat Engine's debugger will stop at 40FAAD.

 Now we can set a hook for AGTH at this address.

 #Now we add “-4” because the character address is in EAX and we get “/HBN-4”.
 #EAX doesn't directly contain the character, instead it contains the address of the character so we need to add “*” getting “/HBN-4*”.

 This tutorial explains how to find an [https://sites.google.com/site/agthook/ AGTH] hook for a Japanese visual novel using [http://www.cheatengine.org/ Cheat Engine]. The game 診てくださいます？ by [http://www.complets.co.jp/ Complet's] will be used as an example. You will need to know the basics of assembler programming. Reading the book “PC Assembly Language” by Paul Carter is recommended. It is short at only 200 pages and was used to teach assembler programming at a university. It can be downloaded for free [http://www.drpaulcarter.com/pcasm/ here]. Windows system locale has to be set to “Japanese” or this tutorial won't work.

 In this tutorial we used instructions that access the text that is constantly changing with every click. It is also possible to use instructions that access the text from the game database.
