Tested for TwMS 241.1 MapleStory.exe
全部5個檔案，下面直接貼 source ，不另附檔案下載

範例中數據皆取自本站的 新 楓之谷(MapleStory) 遊戲代碼分享區

檔案列表:
Assembly.asm
dllmain.cpp
X64AsmSample.sln
X64AsmSample.vcxproj
X64AsmSample.vcxproj.filters

此範例實作:
1. CRC bypass (沒用到 asm)
    注入 dll 後直接寫入

2. Boss 無敵 Asm + 開關
    預設為關
    call SetBossInvincibleEnable(BOOLEAN Enable) 設定開/關

3. 全職業攻擊技能無延遲 Asm + 開關
    預設為關,速度5
    call SetAttackNoDelay(BOOLEAN Enable)  設定開/關
    call SetAttackNoDelayValue(DWORD Value) 設定速度

4. Nt Api Hook Asm + hook function
    以 Hook NtQuerySystemInformation 為例
    當 SystemInformationClass == SystemProcessInformation 時
    印出 pid 跟 process image name

請問這是需要使用DLL注入的方式嗎?
DLL注入會失敗
目前可以編譯完成，但不知道要怎麼使用

建議 使用intel c++

怎麼說呢?? 是有比較好debug 還是說有其方便之處
平常都是用visual studio 寫 C++ & C#
VSC++ 加入 masm 不是也可以編寫嗎?
