We already sorted this out on discord. I just wanna add this here so anyone will maybe benefit from the answer.

A crash right after selecting the character is typically an issue with the resinfo files. The game tries to parse the file, but fails because of a syntax error or a class not being registered. (Which was the case this time).

But it could also be something completely different. DevKit can crash for various reasons. So friendly reminder to anyone: If you are experiencing a crash and you are familiar with a debugging tool like x64dbg, try to figure out the address where the crash is happening. It helps a lot for narrowing down the issue.

What's wrong?

Does your packet have bytes to read? If yes, afair you need to read the packet to the end. The client will be sad otherwise.

Try calling MsgBuffer->FlushRemaining(); before returning.

You have to return 1 as well, if its a custom opcode.

Can you give me a example. I change "return 0" to "return 1" but still crashed!

Ensure about your func address

Code:

reinterpret_cast<int(__thiscall*)(OnPacketHandle*, CMsgStreamBuffer*)>(0x0084CAB0)(this, MsgBuffer);

Because there's no class in SRO called OnPacketHandle and I can't really tell which process you're hooking.

0084CAB0 shall mean CPSMission, so ensure about your bytes as flo mentioned first and the return value. Debugging will help you find it out quickly.

If you're interested, I had a mini-guide about this:

(meanwhile flo's reconstruction is way better, but I like just to stick with my reverse)

Thank #florian0, thank #HB too ^^

Why my character information return don't correctly.

Code:

printf("- Char: %s,  - Level: %d - Strength: %d - Intellect: %d \n",g_pCICPlayer->m_charname.c_str(), g_pCICPlayer->m_level , g_pCICPlayer->m_str_stat, g_pCICPlayer->m_int_stat);

Are you sure that m_charname is not wchar? If its wchar, you need to use wprintf instead.

I don't understand what you mean with stats, but anyways since level & str seems bugged too, then probably its string size that messed up offsets.

You need to ensure to use VC80 as mentioned in main post.
