【破解过程】
首先,查壳Borland Delphi 6.0 - 7.0
OD载入,查找字符串,找到注册错误(有两处,一处为验证,注册码是否是8位,如果不是就报错,),双击跟进,
运行程序输入8位假码,OD断下了

004A9904 |. E8 D7A8F5FF call BatchPic.004041E0
004A9909 \. C3 retn
------------------------------------------------------------------------------------
关键CALL跟进如下:
004AB18C $ 55 push ebp
004AB18D . 8BEC mov ebp,esp
004AB18F . B9 05000000 mov ecx,5
004AB194 > 6A 00 push 0
004AB196 . 6A 00 push 0
004AB198 . 49 dec ecx
004AB199 .^ 75 F9 jnz short BatchPic.004AB194
004AB19B . 53 push ebx
004AB19C . 56 push esi
004AB19D . 57 push edi
004AB19E . 8955 F8 mov dword ptr ss:[ebp-8],edx
004AB1A1 . 8945 FC mov dword ptr ss:[ebp-4],eax
004AB1A4 . 8B45 FC mov eax,dword ptr ss:[ebp-4]
004AB1A7 . E8 E494F5FF call BatchPic.00404690
004AB1AC . 8B45 F8 mov eax,dword ptr ss:[ebp-8]
004AB1AF . E8 DC94F5FF call BatchPic.00404690
004AB1B4 . 33C0 xor eax,eax ; 清零EAX


-----------------中间省略N多代码------------------------------------------------------

004AB456 . E8 A98DF5FF call BatchPic.00404204
004AB45B . C3 retn
004AB45C .^ E9 FF86F5FF jmp BatchPic.00403B60
004AB461 .^ EB DE jmp short BatchPic.004AB441
004AB463 8BC3 mov eax,ebx  关键处,此时EBX是0,只要不让EAX为0,就为注册了
004AB465 . 5F pop edi
004AB466 . 5E pop esi
004AB467 . 5B pop ebx
004AB468 . 8BE5 mov esp,ebp
004AB46A . 5D pop ebp
004AB46B . C3 retn
---------------------------------------------------------------------------------
再改一处
0047B531 /74 10 je short BatchPic.0047B543 ; 已使用多少次CALL,改jmp
0047B533 . |8BD8 mov ebx,eax
0047B535 . |8BD0 mov edx,eax
0047B537 . |8B83 CC020000 mov eax,dword ptr ds:[ebx+2CC]
0047B53D . |FF93 C8020000 call dword ptr ds:[ebx+2C8]
0047B543 > \5B pop ebx

不是明码比较，本人曾经破过。
