Hi,
Can someone help me, I want to know how to change register value (eax) of an address with LUA script ? So I can toggle it enable/disable easily.
And how to implement it in new CE trainer ?
How to view register stack in memory disassembler (I want to know about its value).

Sorry for my bad English, I hope you understand.

the following code simulates a change reg at breakpoint bp
Code:

changeregaddress=0x0045c498 --change this to the address you want
debug_removeBreakpoint(changeregaddress) --remove it if it was set

function debugger_onBreakpoint()
  if (EIP == changeregaddress) then
    hasChangedARegister=true --obsolete in 6.1
    EAX=0
    changedEAX=true  --obsolete in 6.1

    debug_continueFromBreakpoint(0) --run (bug in 6.0: it's always run)
   
    return 1 --I handled it so don't tell the user
  else
    return 0 --unexpected breakpoint, show the the user
  end
end

 
debug_setBreakpoint(changeregaddress)


as to implementing it in the trainer: Just running this code will cause the breakpoint to be set and the handler will work
So just set it under a button or at launch time

To disable just run debug_removeBreakpoint(changeregaddress)


and the register stack will show automatically when you've hit a breakpoint and it's waiting for user intput on how to continue
