1. Structure of Research:

The structure of every technology's research part is quite similar, if not the same. I will take Loom as an example:

RT1-RT2-RT3-RT4-RT5-RT6-COST1-----COST2-----COST3-----RTU-
CIV/UNI-RL--DES-HLP-TIM-EFF-----ICO-SLO

6800FFFFFFFFFFFFFFFFFFFF0300320001FFFF000000FFFF0000000100
FFFF00006D006E1B561F1900160000000600060EA201005E650200FFFF
FFFF05004C6F6F6D00

• 6800: Required Technology 1 = 104 = Dark Age
  
• FFFF: Required Technology 2 = None
  
• FFFF: Required Technology 3 = None
  
• FFFF: Required Technology 4 = None
  
• FFFF: Required Technology 5 = None
  
• FFFF: Required Technology 6 = None
  
• 0300320001: Cost 1 = Gold 50
  
• FFFF000000: Cost 2 = None 0
  
• FFFF000000: Cost 3 = None 0
  
• 0100: Required Technologies Used = 1
  
• FFFF0000: Civilization = all, no specfic
  
• 6D00: Research Location = 109 = Town Center
  
• 6E1B: Description = Resource 7022 [Loom]
  
• 561F: Help Message = Resource 8022 [Research Loom (+15% villager hit points; +1/+1P armor)]
  
• 1900: Research time = 25 Seconds
  
• 1600: Effect Slot = 22 (23th CHUN4)
  
• 0000: Must be 0000
  
• 0600: Icon = 6 (7th Frame)
  
• 06: Button Slot = 6
  
• 0EA20100: Technology Pointer 1 (Long)
  
• 5E650200: Technology Pointer 2 (Long)
  
• FFFFFFFF: Must be FFFFFFFF
  
• 0500: Name Length = 5 bytes (Loom.)
  
• 4C6F6F6D00: Technology Name = Loom.
  

2. Required Technology (16-bit):

"Required Technology 1" always controls in which age the technology will appear. To do this, you can insert the ID of Dark Age, Feudal Age, Castle Age or Imperial Age here to set when the subject will become available to the player.

• 6800(104) = Dark Age
  
• 6500(101) = Feudal Age
  
• 6600(102) = Castle Age
  
• 6700(103) = Imperial Age
  

If you want the player research other technology(-ies) before being available to research the subject (like unit upgrade), you can change the remaining five "Required Technology" slot into the ID of those technology(-ies). It is recommended that the required technology share the same button slot and research location with the subject. Furthermore, you should not forget to alter the "Required Technologies Used" to correct number as well.

3. Cost (16-bit / 16-bit / 8-bit):

The first 2 bytes control which type of resources the technology will cost.

• 0000 = Food
  
• 0100 = Wood
  
• 0200 = Stone
  
• 0300 = Gold
  
• 0400 = Ore (Cancelled)
  

The 3rd to 5th bytes mean the quantity of cost resources. It is in 16 bit.

The last byte is a boolean that determines whether this cost is used or not. Set to 01 to make the cost take effect.

4. Civilization (16-bit / 16-bit):

The first 2 bytes control which civilization(s) can gain access to this technology.

• FFFF = All
  
• 0100 = British
  
• 0200 = French
  
• 0300 = Goths
  
• 0400 = Germans
  
• 0500 = Japanese
  
• 0600 = Chinese
  
• 0700 = Byzantine
  
• 0800 = Persians
  
• 0900 = Saracens
  
• 0A00 = Turks
  
• 0B00 = Vikings
  
• 0C00 = Mongols
  
• 0D00 = Celts
  
• 0E00 = Spanish
  
• 0F00 = Aztecs
  
• 1000 = Mayan
  
• 1100 = Hun
  
• 1200 = Korean
  

The 3rd byte is a boolean that determine whether civilization specification is used for this technology or not. Set to 0100 if the first 2 bytes are not FFFF, or otherwise 0000.

5. Research Location (16-bit):

These 2 bits control in which buildings the technology can be researched.

• 0C00 = Barrack
  
• 2D00 = Dock
  
• 4400 = Mill
  
• 5200 = Castle
  
• 5400 = Market
  
• 5700 = Archery Range
  
• 6500 = Stable
  
• 6700 = Blacksmith
  
• 6800 = Monastery
  
• 6D00 = Town Center
  
• 6E00 = Trade Workshop
  
• D100 = University
  
• 3202 = Lumberjack Camp
  
• 4802 = Mining Camp
  
• BE01 = Port
  

6. Description (16-bit):

Download Resource Hacker to find/edit/insert texts into language.dll, language_x1.dll or language_x1_p1.dll. Then, check the number of the resources and enter the 16 bit version of the amount here.

7. Help Message (16-bit):

Download Resource Hacker to find/edit/insert texts into language.dll, language_x1.dll or language_x1_p1.dll. Then, check the number of the resources and enter the 16 bit version of the amount here.

8. Research time (16-bit):

These 2 bytes control how many game seconds it will take to research the technology.

9. Effect Slot ID (16-bit):

These 2 bytes store the ID of the effect slot (Techage/CHUN4) that contains effects of the technology.

10. Icon ID (16-bit):

Go to AOK Mod pack Studio and look for Resource #50729 under Table 2 of interfac.drs (By Location). Choose the frame with your favourite icon, then reduce the frame number by 1 and input the hex-based result here.

?? | ?? | ?? | ?? | ??
----|----|----|----|----
1A | 1B | 1C | 1D | ??
----|----|----|----|----
?? | ?? | ?? | ?? | ??

12. Technology Name (Text String):

This needs not to be explained, and it is not used by the game either. It is only used for searching where the technology we want to edit is.

Now, let us move on to the 23th CHUN4 (It is because the effect ID slot of Loom is 22):

4348554E340000000000000000000000000000000000000000000000000
000030004FFFF040000000000704104FFFF040008000020804404FFFF04
00080000404044

It would be much better if you arrange them like the following:

4348554E34
0000000000000000000000000000000000000000000000000000
0300
04FFFF0400000000007041(increase villagers' hitpoint by 15)
04FFFF0400080000208044(increase villagers' melee armour by 1)
04FFFF0400080000404044(increase villagers' pierce armour by 1)

• 4348554E34: CHUN4
  
• 03: Number of Effect(s) = 3
  
• 04: Effect Type = Adding Upgrades
  
• 04: Units Affected = Villagers
  
• 0000/0800: Effect Target = Hit Points/Armour
  
• 00007041/00208044/00404044: Effect = 15 units/ Melee 1 unit / Pierce 1 unit
  

Instead of using Loom as an example, I will describe how to set different kinds of effect in the following.

1. Upgrading Effect (8-bit / 16-bit / 16-bit / 32-bit float)

Example: 0307000600FFFF00000000 (Upgrading Skirmishers to Elite Skirmishers)

• 03: Effect Type must be set to 03 to make this effect a units upgrading effect.
  
• 0700: Unit ID of the type of unit/building you want to upgrade to others. In this case, it is set to 7, which means Skirmisher(s).
  
• 0600: Unit ID of the type of unit/building you want the upgrading units change to. In this case, it is set to 6, which means Elite Skirmisher(s).
  
• FFFF: Not Used = FFFF
  
• 00000000: Empty = 00000000
  

2. Enhancing Effect A - Round Number (8-bit / 16-bit / 16-bit / 32-bit float)

Example: 04FFFF0400080000208044(increase villagers' melee armour by 1)

• 04: Effect Type must be set to 04 to make this effect a units enhancing effect.
  
• FFFF: Unit ID. Not used in this case.
  
• 0400: These 2 bytes contain the Unit Class affected by the technology. The numbers of unit classes are listed at here.
  
• 0800: The type of attribute of the unit class that will be changed by the technology. The numbers of unit attributes are:
  
  
  • 00 Hit Point
    
  • 01 Line of Sight
    
  • 02 Garrison
    
  • 03 Unit Size Radius 1
    
  • 04 Unit Size Radius 2
    
  • 05 Movment Speed
    
  • 06
    
  • 07
    
  • 08 Armor
    
  • 09 Attack
    
  • 0A Attack Rate
    
  • 0B Percent Accuracy
    
  • 0C Range
    
  • 0D Working Rate
    
  • 0E Resource Carriage
    
  • 0F
    
  • 10
    
  • 11
    
  • 12
    
  • 13
    
  • 14 Minimum Range
    
  • 15 Population Support
    
  • 16 Blast Radius (Area Damage)
    
  • 17 Search Radius
    
  • 64 Resource Cost
    
  • 65 Creation Time
    
  • 67 Food Cost
    
  • 68 Wood Cost
    
  • 69 Stone Cost
    
  • 6A Gold Cost
    
  • 6C Healing Rate
    
  
  
• 00208044: Calculate the answer of: [Increasing Value] + (256 x Effect Category ID)

  Then, convert the answer into a 32-bit float and input the numbers here. You may want to check the list of Effect Category ID.

  In this case, the answer is: 1 + (256 x 4) = 1025, while the 32-bit float of 1025 is 00208044.
  

3. Enhancing Effect B - Percentage (8-bit / 16-bit / 16-bit / 32-bit float)

Example: 050400FFFF64008195633F(set the cost of archer to 88.9%)

• 05: Effect Type must be set to 05 to make this effect a units enhancing effect.
  
• 0400: Unit ID of the type of unit affected. In this case, 04 means archer.
  
• FFFF: Unit Class ID. The numbers of unit classes are listed at here. Not Used in this case.
  
• 6400: The type of attribute of the unit class that will be changed by the technology. The numbers of unit attributes are:
  
  
  • 00 Hit Point
    
  • 01 Line of Sight
    
  • 02 Garrison
    
  • 03 Unit Size Radius 1
    
  • 04 Unit Size Radius 2
    
  • 05 Movment Speed
    
  • 06
    
  • 07
    
  • 08 Armor
    
  • 09 Attack
    
  • 0A Attack Rate
    
  • 0B Percent Accuracy
    
  • 0C Range
    
  • 0D Working Rate
    
  • 0E Resource Carriage
    
  • 0F
    
  • 10
    
  • 11
    
  • 12
    
  • 13
    
  • 14 Minimum Range
    
  • 15 Population Support
    
  • 16 Blast Radius (Area Damage)
    
  • 17 Search Radius
    
  • 64 Resource Cost
    
  • 65 Creation Time
    
  • 67 Food Cost
    
  • 68 Wood Cost
    
  • 69 Stone Cost
    
  • 6A Gold Cost
    
  • 6C Healing Rate
    
  
  
• 8195633F: Convert the percentage (in decimal figure) into a 32-bit float and input the numbers here. In this case, the 32-bit float of 0.889 is 8195633F.
  

4. Enabling Effect (8-bit / 16-bit / 16-bit / 32-bit float)

Example: 0217010100FFFF00000000(Enabling Scorpions to be created by the player)

• 02: Effect Type must be set to 02 to make this effect a units enabling effect.
  
• 1701: Unit ID of the type of unit/building you want the upgrading units change to. In this case, it is set to 279, which means Scorpion(s).
  
• 0100: These 2 bytes must be set to 0100.
  
• FFFF: Not Used, set to FFFF.
  
• 00000000: Empty = 00000000

Where and Whether the unit/building creating button will appear are preset by the game, changing them requires unit-editing.
