汇编MOV EBX,[EAX+ECX] 这段如何等价替换？

0045A3CC这段如何等价替换？我是菜鸟啊。。。

0045A3C3: 72 F2 JB SHORT 0045A3B7
0045A3C5: C3 RETN
0045A3C6: 61 POPAD
0045A3C7: B9 FC4B0900 MOV ECX,94BFC
0045A3CC: 8B1C08 MOV EBX,[EAX+ECX]
0045A3CF: 8999 00104000 MOV [ECX+401000],EBX
0045A3D5: E2 F5 LOOPD SHORT 0045A3CC
0045A3D7: 90 NOP
0045A3D8: 90 NOP
0045A3D9: BA 00004000 MOV EDX,400000
0045A3DE: BE 00E00900 MOV ESI,9E000
0045A3E3: 01D6 ADD ESI,EDX
0045A3E5: 8B46 0C MOV EAX,[ESI+C]
0045A3E8: 85C0 TEST EAX,EAX
0045A3EA: 0F84 87000000 JE 0045A477
0045A3F0: 01D0 ADD EAX,EDX
0045A3F2: 89C3 MOV EBX,EAX
0045A3F4: 50 PUSH EAX
一楼的即使包括下面2个NOP我也没那么多空间...

Answer 1

0045A3C7: B9 FC4B0900 MOV ECX,94BFC
0045A3CC: 8B1C08 MOV EBX,[EAX+ECX]
0045A3CF: 8999 00104000 MOV [ECX+401000],EBX
0045A3D5: E2 F5 LOOPD SHORT 0045A3CC
整体下移两个字节
注意LOOPD SHORT 0045A3CC的地址

Answer 2

MOV DS:94BFC+401000,EBX

Answer 3

问题说的不明白！

Answer 4

不知道你什么意思，你可以把MOV EDX,400000，挪到前面
反正也不影响什么，前后换一换
注意修正相对跳转的地址
