不建議爆破，因為通過註冊後他會把註冊明肯註冊碼儲存在pmlxzj.dll文件裡，再次起動時會再檢查，

C:\windows\pmlxzj.dll

我的機器碼為"38289378"，輸入註冊名為「123"
下斷點在：
0043800C |> 8B85 3CFFFFFF /mov eax,dword ptr ss:[ebp-C4]
00438012 |. 0FBE9405 18FFFFFF |movsx edx,byte ptr ss:[ebp+eax-E8];[ebp+eax-0E8h]=temp_D
可見[ebp+eax-E8]指向"31 33 36 33 30 00"
可得：
31h+14h=45h->"E"
33h+14h=49h->"G"
36h+14h=4Ah->"K"
33h+14h=49h->"G"
30h+14h=44h->"D"
"EGKGD"為前5位註冊碼
再下斷點在：
004380AD |. 0FBE8C05 D0FEFFFF movsx ecx,byte ptr ss:[ebp+eax-130]；[ebp+eax-130]=第5位註冊碼
004380B5 |. 83C1 BF add ecx,-41
004380B8 |. 2BCA sub ecx,edx
可得到edx=1
所以第5位註冊碼為：1+41h=44h->"B" 或1+41h+5=49h->"G" 我的註冊碼為"EGKGDB"或"EGKGDG"

但是，一般用後面的比較好~ ，因為後面的支持未來版本，
此外，我們用這種方法註冊後，我們做出來的所有東西除了.exe 得錄像之外都沒有問題了，關鍵還在
play.dat 裡面的算法，是這 6位註冊碼後面的東西，因為我沒有偵錯，所以用 空格填充的話，我們的

自訂版權
出不來的，即使出來了也不能改字體，字號~ 所以我們還要分析一下 play.dat 裡面的構造~

說了這麼多，相信朋友們都應該知道 天狼星 這個 變態 的註冊碼
校驗方式了吧~ 利用上面的 主程序 註冊碼 計算方式，做出來個
偽註冊機，因為算出來的註冊碼，只能用在主程序上面，做出來的
.EXE 的錄像 還是有 未註冊的 標誌，所以我覺得爆了他比較不錯，
一個原因是 去掉了 未註冊的標誌，還有一個原因就是 如果 把
PLAY.DAT 裡面的 未註冊用空格覆蓋，我們的 自訂 訊息就不可以
改字體，字號，顏色等等~~~
