== Starting Resources ==
Table with the starting resources starts at 0x278170. Each 4 bytes are the next resource (Wood, Mercury, Ore, Sulfur, Crystal, Gems, Gold). Each 28 bytes is the next difficulty - Easy, Normal, Expert, etc. At 0x2781FC the AI resources start and follow the same order of resources and difficulties. The whole table thus takes 280 bytes. 

== Starting Bonuses ==
=== Gold Bonus ===
The starting gold bonus chooses a random value between the value written at 0x0C0002 and the value at 0x0BFFFD, and then multiplies it by 100. To change the multiplication, simply edit 0x0C000B (multiplying by 25) and 0x0C0016 (moving the value by 2 bits, so multiplying it by 4). 

=== Resource Bonuses ===
The starting resource bonuses use DWORD pointers to find their appropriate code to run:
* Wood and Ore - AF FF 4B 00 
* Crystals - D6 FF 4B 00 
* Gems - E1 FF 4B 00 
* Mercury - EC FF 4B 00 
* Sulfur - F4 FF 4B 00 

These DWORD pointers are located at the following addresses: 
* Castle - 0x0C01B4 
* Rampart - 0x0C01B8 
* Tower - 0x0C01BC 
* Inferno - 0x0C01C0 
* Necropolis - 0x0C01C4 
* Dungeon - 0x0C01C8 
* Stronghold - 0x0C01CC 
* Fortress - 0x0C01D0 
* Conflux - 0x0C01D4 

Note, that you need to edit ScnrStar.def to reflect any altered resources. 

The amount for each rare resource is most likely determined by the function at 0xc009e: {{unk}}
: minimum: c745f0 33333333 ''(mov [ebp-0x10], 0x33333333)'' c745f0 3333EB3F  ''(mov [ebp-0x1c], 0x3feb3333)'' 
: break between the two: eb 0e ''(jmp 0x0e)'' 
: maximum: c745f0 66666666 ''(mov [ebp-0x10], 0x66666666)'' c745f0 6666E63F  ''(mov [ebp-0x10], 0x3FE66666)'' 

The amount of wood and ore are most likely specified at 0xbffaf: BA 0a000000 ''(mov edx, 0x0a)'' B9 05000000 ''(mov ecx, 0x05)'' 

== Movement point reminder ==
The movement point reminder is located at 0x9c91. It checks if movement points are 0 (using a 2-byte ''test eax, eax'') and then proceeds to different code if movement points are (or not) zero. If one wants to change it to a higher number (to avoid reminding of movement for heroes that can't actually move anymore), the following code can be used:

:0x9c91: {{---}}{{---}}a1 c8876900 ''mov eax, [0x6987c8]'' e9 849d0d00 (jump to some arbitrary free space) 90909090
: free space: {{-}}3d XY000000 ''cmp eax, XY'' - compare movement points with value XY. 
:::: {{---}}7F 0A ''jg 0x0a'' - jump 10 bytes if the value is greater. 
:::: {{---}}A1 C4 5d 6A 00 - displaced code
:::: {{---}}e9 6f62f2ff - jump to 0x9c9f (or 49C9F)
:::: {{---}}e9 a462f2ff - jump to 0x9cd9 (or 49CD9).
