MEMO2

BDO client (and XIGNCODE3) does not check CRC codes on each packed files.

MEMO3

I could disable secure code using modification of global_utils.luac (TESTED on 2016/08/28)

function isItemMarketSecureCode()
  local isSecureCode = true  -- Change this to false
  if (isGameTypeKorea() or isGameTypeJapan() or isGameTypeRussia() or isGameTypeEnglish() or isGameTypeTaiwan()) and true == isSecureCode then
    return true
  else
    return false
  end
end

On 2016/11/03 patch, secure code is disabled on KR client.
