How to crack (chinese net ease new flyff) cflyff wdf file?
I have used WdfRes_V1.1.24.exe to unpack wdf files, many bin files, how to find certain types (dds, o3d, chr, ani) map resources, etc.

How to crack (chinese net ease new flyff) cflyff wdf file?
I have used WdfRes_V1.1.24.exe to unpack wdf files, many bin files, how to find certain types (dds, o3d, chr, ani) map resources, etc.
Each file goes through StringID to output a uid. If i remember I took the code from the official windsoul site.Code:/** @brief Chinese version of the game */
inline unsigned long string_id(const char* str)
{
static unsigned int m[70]{};
strncpy(reinterpret_cast<char*>(m), str, 256);
unsigned int i = 0;
for (; i < 256 / 4 && m[i]; ++i)
{
}
m[i++] = 0x9BE74448;
m[i++] = 0x66F42C48;
unsigned int v = 0xF4FA8928;
unsigned int edi = 0x7758B42B;
unsigned int esi = 0x37A8470E;
for (unsigned int ecx = 0; ecx < i; ++ecx)
{
unsigned int ebx = 0x267B0B11;
v = (v << 1) | (v >> 0x1F);
ebx ^= v;
unsigned int eax = m[ecx];
esi ^= eax;
edi ^= eax;
unsigned int edx = ebx;
edx += edi;
edx |= 0x02040801;
edx &= 0xBFEF7FDF;
long long num = edx;
num *= esi;
eax = static_cast<unsigned>(num);
edx = static_cast<unsigned>(num >> 0x20);
if (edx != 0)
eax++;
num = eax;
num += edx;
eax = static_cast<unsigned>(num);
if (static_cast<unsigned>(num >> 0x20) != 0)
eax++;
edx = ebx;

Thanks for your reply, I don't know how to use this code, can you give an application example?
I only tested one file, output uid, what's next?
unsigned long test = string_id("3F3C8682.bin"); // 3072123180
