KiriKiri hook:
  Usually there are xp3 files in the game folder but also exceptions.
  Find TVP(KIRIKIRI) in the version description is a much more precise way.

  KiriKiri1 correspond to AGTH KiriKiri hook, but this doesn't always work well.
  Find call to GetGlyphOutlineW and go to function header. EAX will point to a
  structure contains character (at 0x14, [EAX+0x14]) we want. To split names into
  different threads AGTH uses [EAX], seems that this value stands for font size.
  Since KiriKiri is compiled by BCC and BCC fastcall uses EAX to pass the first
  parameter. Here we choose EAX is reasonable.
  KiriKiri2 is a redundant hook to catch text when 1 doesn't work. When this happens,
  usually there is a single GetTextExtentPoint32W contains irregular repetitions which
  is out of the scope of KS or KF. This time we find a point and split them into clean
  text threads. First find call to GetTextExtentPoint32W and step out of this function.
  Usually there is a small loop. It is this small loop messed up the text. We can find
  one ADD EBX,2 in this loop. It's clear that EBX is a string pointer goes through the
  string. After the loop EBX will point to the end of the string. So EBX-2 is the last
  char and we insert hook here to extract it.

 *
 *  This engine will hook to the caller of caller of the first GetGlyphOutlineW (totally three).
 *  The logic is quite similar to KiriKiri1 except it backtrack twice to get the function call.
 *
 *  1/31/2015: If the game no longer invoke GDI functions by default, one way to find the hook

 *  See: krkrz/src/core/visual/LayerIntf.cpp
 *  API: http://devdoc.kikyou.info/tvp/docs/kr2doc/contents/f_Layer_drawText.html
 *
 *  Debug method:
 *  Backtrack from GetGlyphOutlineW, and find the first function that is invoked more
 *  times than (cached) GetGlyphOutlineW.
 *
 *  - Find function calls to GetGlyphOutlineW (totally three)
 *
 *  - Find the caller of the first GetGlyphOutlineW
 *    Using MemDbg::findCallerAddressAfterInt3()
 *
 *  - Find the caller of the above caller
 *    Since the function address is dynamic, the function is found using KiriKiriZHook

 *  I randomly picked a pattern from VBH:
 *
 *    011a7a95   33c0             xor eax,eax
 *    011a7a97   3843 20          cmp byte ptr ds:[ebx+0x20],al

BGI hook:
  Usually game folder contains BGI.*. After first run BGI.gdb appears.

  BGI engine has font caching issue so the strategy is simple.
  First find call to TextOutA or TextOutW then reverse to function entry point,
  until full text is caught.
  After 2 tries we will get to the right place. Use ESP value to split text since

  At some point the beginning four bytes to search for were removed, but the difference below were not corrected? Or maybe they were?
  I don't have all these games so no way to confirm which (if any) are wrong.
  But the first difference (the important one since it's the one detecting offset=arg3, all others give new) seems to be four bytes off when hooking https://vndb.org/v8158
  ...but maybe it's not? Maybe I discovered a new difference?
  I think the safest option is to just add the new? difference as a case that detects offset=arg3 since either way one case will detect offset=arg3 correctly.
  And all the other cases fall through to offset=arg2.

Reallive hook:

  Technique to find Reallive hook is quite different from 2 above.
  Usually Reallive engine has a font caching issue. This time we wait

 *  jichi 8/16/2013: Insert new siglus hook
 *  See (CaoNiMaGeBi): http://tieba.baidu.com/p/2531786952
 *  Issue: floating text
 *  Example:
 *  0153588b9534fdffff8b43583bd7
 *  0153 58          add dword ptr ds:[ebx+58],edx
 *  8b95 34fdffff    mov edx,dword ptr ss:[ebp-2cc]
 *  8b43 58          mov eax,dword ptr ds:[ebx+58]
 *  3bd7             cmp edx,edi    ; hook here
 *
 *  /HW-1C@D9DB2:SiglusEngine.exe

 *  - text_fun: 0x0
 *  - function: 0
 *  - hook_len: 0
 *  - ind: 0
 *  - length_offset: 1

 *
 *  10/19/2014: There are currently two patterns to find the function to render scenario text.
 *  In the future, if both of them do not work again, try the following pattern instead.
 *  It is used to infer SiglusEngine2's logic in vnragent.

MAJIRO hook:
  Game folder contains both data.arc and scenario.arc. arc files is
  quite common seen so we need 2 files to confirm it's MAJIRO engine.

  Font caching issue. Find call to TextOutA and the function entry.

  The original Majiro hook will catch furiga mixed with the text.
  To split them out we need to find a parameter. Seems there's no
  simple way to handle this case.
  At the function entry, EAX seems to point to a structure to describe
  current drawing context. +28 seems to be font size. +48 is negative
  if furigana. I don't know exact meaning of this structure,
  just do memory comparisons and get the value working for current release.

  After several tries we comes to address in rvmm.dll and everything is catched.
  We see CALL [E*X+0x*] while EBP contains the character data.
  It's not as simple to reverse in rugp at run time as like reallive since rugp dosen't set
  up stack frame. In other words EBP is used for other purpose. We need to find alternative
  approaches.
  The way to the entry of that function gives us clue to find it. There is one CMP EBP,0x8140
  instruction in this function and that's enough! 0x8140 is the start of SHIFT-JIS
  characters. It's determining if ebp contains a SHIFT-JIS character. This function is not likely
  to be used in other ways. We simply search for this instruction and place hook around.

System40 hook:
  System40 is a game engine developed by Alicesoft.
  Afaik, there are 2 very different types of System40. Each requires a particular hook.

  Pattern 1: Either SACTDX.dll or SACT2.dll exports SP_TextDraw.
  The first relative call in this function draw text to some surface.
  Text pointer is return by last absolute indirect call before that.
  Split parameter is a little tricky. The first register pushed onto stack at the begining
  usually is used as font size later. According to instruction opcode map, push
  eax -- 50, ecx -- 51, edx -- 52, ebx --53, esp -- 54, ebp -- 55, esi -- 56, edi -- 57
  Split parameter value:
  eax - -8,   ecx - -C,  edx - -10, ebx - -14, esp - -18, ebp - -1C, esi - -20, edi - -24
  Just extract the low 4 bit and shift left 2 bit, then minus by -8,
  will give us the split parameter. e.g. push ebx 53->3 *4->C, -8-C=-14.
  Sometimes if split function is enabled, ITH will split text spoke by different
  character into different thread. Just open hook dialog and uncheck split parameter.
  Then click modify hook.

  Pattern 2: *engine.dll exports SP_SetTextSprite.
  At the entry point, EAX should be a pointer to some structure, character at +0x8.
  Before calling this function, the caller put EAX onto stack, we can also find this
  value on stack. But seems parameter order varies from game release. If a future
  game breaks the EAX rule then we need to disassemble the caller code to determine
  data offset dynamically.

/********************************************************************************************
ShinaRio hook:
  Game folder contains rio.ini.
  Problem of default hook GetTextExtentPoint32A is that the text repeat one time.
  But KF just can't resolve the issue. ShinaRio engine always perform integrity check.
  So it's very difficult to insert a hook into the game module. Freaka suggests to refine
  the default hook by adding split parameter on the stack. So far there is 2 different
  version of ShinaRio engine that needs different split parameter. Seems this value is
  fixed to the last stack frame. We just navigate to the entry. There should be a
  sub esp,* instruction. This value plus 4 is just the offset we need.

  New ShinaRio engine (>=2.48) uses different approach.

  Becomes common recently. I first encounter this game in Whirlpool games.
  Problem is name is repeated multiple times.
  Step out of function call to TextOuA, just before call to this function,
  there should be a piece of code to calculate the length of the name.
  This length is 2 for single character name and text,
  For a usual name this value is greater than 2.

EMEHook hook: (Contributed by Freaka)
  EmonEngine is used by LoveJuice company and TakeOut. Earlier builds were apparently
  called Runrun engine. String parsing varies a lot depending on the font settings and
  speed setting. E.g. without antialiasing (which very early versions did not have)
  uses TextOutA, fast speed triggers different functions then slow/normal. The user can
  set his own name and some odd control characters are used (0x09 for line break, 0x0D
  for paragraph end) which is parsed and put together on-the-fly while playing so script
  can't be read directly.

CandySoft hook:
  Game folder contains many *.fpk. Engine name is SystemC.

  AGTH /X3 will hook lstrlenA. One thread is the exactly result we want.
  But the function call is difficult to located programmatically.
  I find a equivalent points which is more easy to search.
  The script processing function needs to find 0x5B'[',
  so there should a instruction like cmp reg,5B
  Find this position and navigate to function entry.
  The first parameter is the string pointer.
  This approach works fine with game later than つよきす２学<EFBFBD>

  But the original つよき<EFBFBD>is quite different. I handle this case separately.

 *  2/12/2015 jichi: SystemAoi5
 *
 *  Note that BUNNYBLACK 3 also has SystemAoi5 version 4.1
 *
 *  Hooked to PgsvTd.dll for all SystemAoi engine, which contains GDI functions.
 *  - Old: AoiLib.dll from DrawTextExA
 *  - SystemAoi4: Aoi4.dll from DrawTextExW
 *  - SystemAoi5: Aoi5.dll from GetGlyphOutlineW
 *
 *  Logic:
 *  - Find GDI function (DrawTextExW, etc.) used to paint text in PgsvTd.dll
 *  - Then search the function call stack, to find where the exe module invoke PgsvTd
 *  - Finally insert to the call address, and text is on the top of the stack.

 *  P.S.: Another approach
 *  See: http://tieba.baidu.com/p/2425786155
 *  Quote:
 *  I guess this post should go in here. I got sick of AGTH throwing a fit when entering the menus in Wolf RPG games, so I did some debugging. This is tested and working properly with lots of games. If you find one that isn't covered then please PM me and I'll look into it.
 *
 *  Wolf RPG H-code - Use whichever closest matches your Game.exe
 *  /HBN*0@454C6C (2010/10/09 : 2,344KB : v1.31)
 *  /HBN*0@46BA03 (2011/11/22 : 2,700KB : v2.01)
 *  /HBN*0@470CEA (2012/05/07 : 3,020KB : v2.02)
 *  /HBN*0@470D5A (2012/06/10 : 3,020KB : v2.02a)
 *
 *  ith_p.cc:Ith::parseHookCode: enter: code = "/HBN*0@470CEA"
 *  - addr: 4656362 ,
 *  - length_offset: 1
 *  - type: 1032 = 0x408
 *
 *  Use /HB instead of /HBN if you want to split dialogue text and menu text into separate threads.
 *  Also set the repetition trace parameters in AGTH higher or it won't work properly with text-heavy menus. 64 x 16 seems to work fine.
 *
 *  Issues:
 *  AGTH still causes a bit of lag when translating menus if you have a lot of skills or items.
 *  Using ITH avoids this problem, but it sometimes has issues with repetition detection which can be fixed by quickly deselecting and reselecting the game window; Personally I find this preferable to menu and battle slowdown that AGTH sometimes causes, but then my PC is pretty slow so you might not have that problem.
 *
 *  Minimising the AGTH/ITH window generally makes the game run a bit smoother as windows doesn't need to keep scrolling the text box as new text is added.
 *
 *  RPG Maker VX H-code:
 *  Most games are detected automatically and if not then by using the AGTH /X or /X2 or /X3 parameters.
 *
 *  Games that use TRGSSX.dll may have issues with detection (especially with ITH).
 *  If TRGSSX.dll is included with the game then this code should work:
 *  /HQN@D3CF:TRGSSX.dll
 *
 *  With this code, using AGTH to start the process will not work. You must start the game normally and then hook the process afterwards.
 *  ITH has this functionality built into the interface. AGTH requires the /PN command line argument, for example:
 *  agth /PNGame.exe /HQN@D3CF:TRGSSX.dll /C
 *
 *  Again, drop the N to split dialogue and menu text into separate threads.

/********************************************************************************************
AkabeiSoft2Try hook:
  Game folder contains YaneSDK.dll. Maybe we should call the engine Yane(屋<EFBFBD> = roof)?
  This engine is based on .NET framework. This really makes it troublesome to locate a
  valid hook address. The problem is that the engine file merely contains bytecode for
  the CLR. Real meaningful object code is generated dynamically and the address is randomized.
  Therefore the easiest method is to brute force search whole address space. While it's not necessary
  to completely search the whole address space, since non-executable pages can be excluded first.
  The generated code sections do not belong to any module(exe/dll), hence they do not have
  a section name. So we can also exclude executable pages from all modules. At last, the code
  section should be long(>0x2000). The remain address space should be several MBs in size and
  can be examined in reasonable time(less than 0.1s for P8400 Win7x64).
  Characteristic sequence is 0F B7 44 50 0C, stands for movzx eax, word ptr [edx*2 + eax + C].
  Obviously this instruction extracts one unicode character from a string.
  A main shortcoming is that the code is not generated if it hasn't been used yet.
  So if you are in title screen this approach will fail.

 *  The old hook no longer works for new game.
 *  Sample game: [150129] [honeybee] RE:BIRTHDAY SONG
 *
 *  Note, WillPlus engine is migrating to UTF16 using GetGlyphOutlineW such as:
 *      [141218] [Guily] 手<EFBFBD>めにされる九人の堕女
 *  This engine does not work for GetGlyphOutlineW, which, however, does not need a H-code.
 *
 *  See: http://sakuradite.com/topic/615
 *
 *  There WillPlus games have many hookable threads.
 *  But it is kind of important to find the best one.
 *
 *  By inserting hw point:
 *  - There is a clean text thread with fixed memory address.
 *    However, it cannot extract character name like GetGlyphOutlineA.
 *  - This is a non-clean text thread, but it contains garbage such as %LC.
 *
 *  By backtracking from GetGlyphOutlineA:
 *  - GetGlyphOutlineA sometimes can extract all text, sometimes not.
 *  - There are two GetGlyphOutlineA functions.
 *    Both of them are called statically in the same function.
 *    That function is hooked.

	Sample games: https://vndb.org/r54549 https://vndb.org/v22705
	Not too sure about the stability of this pattern, but it works for both of the above
	Hook code for first game: /HQ-8*0@43D620. This seems fairly stable: __thiscall calling convention and first member points to string
	Method to find hook code: trace call stack from GetGlyphOutlineW
	Disassembly from first game (damekoi). The first few instructions are actually a common function prologue: not enough to locate hook
	Hooking SysAllocString also seems to work, but has some garbage

/**
 *  jichi 5/11/2014: Hook to the beginning of a function
 *
 *  Executable description shows "AVGEngineV2"
 *
 *  Cached wrong text can also be found in GetGlyphOutlineW.
 *
 *  4/27/2015 old logic:
 *  1. find the following location
 *     00A78144   66:833C70 00     CMP WORD PTR DS:[EAX+ESI*2],0x0
 *     i.e. 0x66833C7000
 *     There are several matches, the first one is used.
 *  2. find the first push operation after it
 *  3. find the function call after push, and hook to it
 *     The text is in the arg1, which is character by character
 *
 *  But in the new game since ウルスラグ<EFBFBD> there the function call is not immediately after 0x66833C7000 any more.
 *  My own way to find the function to hook is as follows:
 *  1. find the following location
 *     00A78144   66:833C70 00     CMP WORD PTR DS:[EAX+ESI*2],0x0
 *     i.e. 0x66833C7000
 *     There are several matches, the first one is used.
 *  2. Use Ollydbg to debug step by step until the first function call is encountered
 *     Then, the text character is directly on the stack
 *
 *  Here's an example of Demonion II (reladdr = 0x18c540):
 *  The text is displayed character by character.
 *  sub_58C540 proc near
 *  arg_0 = dword ptr  8 // LPCSTR with 1 character
 *
 *  0138C540  /$ 55             PUSH EBP

 *  Observations from Debug:
 *  - Ollydbg got UTF8 text memory address
 *  - Hardware break points have loops on 0x4010ED
 *  - The hooked function seems to take 3 parameters, and arg3 is the right text
 *  - The text appears character by character
 *
 *  Runtime stack:
 *  - return address
 *  - arg1 pointer's pointer
 *  - arg2 text
 *  - arg3 pointer's pointer
 *  - code address or -1, maybe a handle
 *  - unknown pointer
 *  - return address

/** 12/23/2014 jichi: Mink games (not sure the engine name)
 *  Sample game:
 *  - [130111] [Mink EGO] お<EFBFBD>ちも<EFBFBD>にはぜったい言えなぁ<EFBFBD>ぁ<EFBFBD>つなこと<EFBFBD>-- /HB-4*0:64@45164A
 *  - [141219] [Mink] しすた<EFBFBD>・すきーむ3
 *
 *  Observations from sisters3:
 *  - GetGlyphOutlineA can get text, but it is cached.
 *  - It's caller's first argument is the correct text, but I failed to find where it is called
 *  - Debugging text in memory caused looping
 *
 *  /HB-4*0:64@45164A
 *  - addr: 0x45164a
 *  - length_offset: 1
 *  - split: 0x64
 *  - off: 0xfffffff8 = -8
 *  - type: 0x18
 *
 *  Observations from Onechan:
 *  - There are lots of threads
 *  - The one with -1 split value is correct, but not sure for all games
 *  - The result texts still contain garbage, but can be split using return values.

 *  jichi 5/22/2015: Insert Bootup hook
 *  Sample games:
 *  - [090709] [PIL] 仏蘭西少女
 *  - [110318] [Daisy2] 三国恋戦<EFBFBD> *  - [110329] [PIL/SLASH] 神学校
 *  - [150527] [Daisy2] 絶対階級学<EFBFBD> *
 *  Properties
 *  - There is Bootup.dat existing in the game folder.
 *  - lstrlenW can find text repeating once
 *  - GetCharABCWidthsW and TextOutW can find cached text that missing characters
 *    GetCharABCWidthsA and TextOutA for old games.
 *  - There is only one TextOut (W for new and A for old).
 *
 *  Logic:
 *  + GDI hook
 *    - Hook to the caller of TextOut
 *  + Lstr hook
 *    - Find last (second) caller of the first GetCharABCWidths after int3
 *    - Find the lstrlen function in this caller, and hook to it
 *
 *  Full text is in arg1, shifted one by one.
 *  Character to paint is also in arg3
 *
 *  All Bootup games are slightly different
 *  - 三国恋戦<EFBFBD>仏蘭西少女: text in both lstrlenA and caller of TextOutA
 *    But I didn't find correct lstrlenA to hook. BootupLstrA find nothing for 仏蘭西少女 and name for 三国恋戦<EFBFBD>
 *  - 神学校: text in both lstrlenW and TextOutW, but lstrlenW has repetition
 *    Caller of TextOutW the same as that of TextOutA
 *  - 絶対階級学<EFBFBD> text in both lstrlenW and TextOutW. But TextOutW's name has repetition
 *    Caller of TextOutW different 神学校
