Hello!

I have a code that searchs for and replaces some AOBs:

Code:

function replace(searchV, replaceV)
  if type(searchV) ~= "table" then
    searchV = {(assert(tonumber(searchV),"Could not convert first argument to number"))}
  end
 
  for i,v in ipairs(searchV) do
    local res = AOBScan(v, "+W-C", 1, 4)
    if res then
      for j=0, res.Count-1, 1 do
        writeBytes(res[j], replaceV)
      end
      res.destroy()
    end
  end
end

local aobs = {
'F4 01 00 00 D0 07 00 00 F4 01',
'20 03 00 00 F4 01 00 00 20 03',
'E8 03 00 00 DC 05 00 00 20 03',
'FA 00 00 00 00 00 00 00 26 02',
'78 05 00 00 00 00 00 00 58 02',
'C8 00 00 00 00 00 00 00 78 05',
'C8 00 00 00 00 00 00 00 08 07',
'F4 01 00 00 00 00 00 00 F4 01',
'20 03 00 00 E8 03 00 00 20 03',
'03 00 00 E8 03 00 00 20 03',
'20 03 00 00 00 00 00 00 20 03'
}

-- pass a table of bytes rather than a string that are parsed into bytes
replace(aobs, {01,00,00,00,00,00,00,00,01,00})


I want to restore the values to its original values after they have been replaced.

I can't figure a correct way to keep track of changed addresses.
I will be glad if someone give me a code example for it.

Many thanks in advance!

You asked this just the other day, and FreeER gave you an example.
