So, I have a pointer that contains the address of a structure start (program.exe+F19390) and four offsets that contain values that I'd like to change after every restart: F8, 100, 104, 108. I'm having a much harder time creating a script that updates the values after restart than I feel like I should be. Any help would be much appreciated!

Find some instruction that accesses that static address (program.exe+F19390) and do a code injection / AoB injection on that.

For example, let's assume lea esi,[ebx+24] accesses that address, and ebx stores the address program.exe+F19390. Then:

Code:
[ENABLE]
aobscan(DERP,68 65 72 70 20 64 65 72 70) // should be unique
alloc(newmem,512)

label(return)

registersymbol(DERP)

newmem:
  lea esi,[ebx+24]
  push eax
  mov eax,[ebx]
  mov [eax+F8],64
  mov [eax+100],64
  mov [eax+104],64
  mov [eax+108],64
  pop eax
  jmp return

DERP:
  jmp newmem
  nop
return:

[DISABLE]

DERP:
  db 68 65 72 70 20 64 65 72 70

dealloc(newmem)

I don't know if lea esi,[ebx+24] has enough bytes for a jump, but you should get the idea.
