Hello, I am a beginner, I am gradually mastering the program, I would like to learn how to make trainers. For example, I would like to make a similar trainer for the game One Piece Burning Blood, in which it will be possible to adjust the control of player 1 to control the computer. For example, here are a couple of trainers with such a function for other games ... could you tell me how to create my own trainer using their example? Is it difficult, where do I start...


Code:
[ENABLE]
aobscanmodule(cpuvs,StreetFighterV.exe,89 9F 8C 01 00 00 41)
alloc(newmem,$100,cpuvs)
registersymbol(cpuvs)
label(code)
label(return)
newmem:
code:
  mov [rdi+0000018C],2
  jmp return
cpuvs:
jmp newmem
  nop
return:
[DISABLE]
cpuvs:
db 89 9F 8C 01 00 00
unregistersymbol(cpuvs)
dealloc(newmem)
