由於過濾清單太長，請自行添加。
附件是我常用的過濾清單。

XD，这个物品过滤可以缩减的，缩减后顶多就是和原样CRC数据一样，还是ICS只不过会多出一行代码。

代碼如果這樣精簡
似乎會把所有東西都過濾掉

movd xmm0,eax
cvtdq2ps xmm0,xmm0
divss xmm0,[03A0395C]
movss [ebx+00000110],xmm0
這邊很重要不能簡略

movd xmm0,eax
cvtdq2ps xmm0,xmm0
divss xmm0,[03A0395C]

这段代码执行后eax也不是物品ID， 必须要调用下面的call后，eax才有物品id。要不就是所有东西都屏蔽了。。
