【过 程】
首先Peid查看壳信息，PECompact 1.68 - 1.84 -> Jeremy Collake，用UnPECompact 1.32脱壳，ImportREC修复输入表。然而还是非法操作，
OEP不知为何不对，最后使用Peid查到的OEP，OK了.
Delphi程序当然是用DEDE，在 frmSWFPlayer的OnCreate事件

一目了然,取注册码1 5 9 13 3 7 11 15 组成新字符串与004C97EC计算出字符串值比较。
sub_004C97EC好像调用了CRC32算法来生成注册码

004C979F 46 inc esi
004C97A0 48 dec eax
004C97A1 75DC jnz 004C977F
...
4D5244处是一张标准的crc32数据表。
等等，这只是奇数位还有偶数呢，别急，继续看 frmAbout窗体的FormCreate事件

sub_004C9A20的内容和前面的差不多
是将取注册码2 6 10 14 4 8 13 16 组成新字符串与004C97EC计算出字符串值比较。
很简单吧，明码比较的，懒得写注册机了，^_^。
