温柔一点，好吗？——暴破pt的另一种方法
作者：kingtall
目标：Performance Test v3.4 build 1000，以下简称pt。
工具：w32dasm8.93,trw1.22
运行pt，看about框，有'Evaluation version'字样。
用w32dasm反汇编pt.ext，找Evaluation version，找到如下

|:004096D2 , :0040990D
|
:00408680 A148194400 mov eax, dword ptr [00441948]；若不为0就显示Evaluation version

现在只要找到程序中把[441948]置0的地方，我是这样做的，在w32dasm的Disassembler菜单中选Save Disassemble text file and create project file，保存结果为pt.alf。然后用写字板打开pt.alf，找481944，找到下面这一段
* Referenced by a (U)nconditional or (C)onditional Jump at Address:

:0040E40D 8BFE mov edi, esi
:0040E40F 83C9FF or ecx, FFFFFFFF

:0040E414 F2 repnz
:0040E415 AE scasb
:0040E416 F7D1 not ecx
:0040E418 49 dec ecx
:0040E419 83F903 cmp ecx, 00000003
:0040E41C 7244 jb 0040E462 ；把这一句改为 eb0f jmp 40e42d
^^^^ 就是注册版了。
:0040E41E 837B74FF cmp dword ptr [ebx+74], FFFFFFFF
:0040E422 753E jne 0040E462
:0040E424 80BB8000000037 cmp byte ptr [ebx+00000080], 37
:0040E42B 7535 jne 0040E462
:0040E42D C7054819440000000000 mov dword ptr [00441948], 0 ；在这里把[441948]置0。
^^^^^^
还有一点，程序启动时会先出现一个小窗口，等好长时间才能进入主窗口，好烦哪！
运行TRW，load pt.exe，下bpx sleep，找到下面（用w32dasm找sleep也一样）
0167:00409547 68DC050000 PUSH DWORD 05DC ；改为 6800000000 push dword 0
^^^^ 少睡点吧！
0167:0040954C FF1528314200 CALL `KERNEL32!Sleep`
这个玩意用了base64算法
