[Help] What does ijl15.dll do?

[ngnam87]

i'm trying to understand a bit of LEN.dll
so here is my question
- does ijl15.dll deicide what dll will load into maplestory process?
- is it packed? (used tool to look into, maybe it's not packed but i see in IDA many sub_xxxxxx function)
- can it be modify to load external dll like LegitLisa IPRedirect?(cause the dll injector not work on some machine)

2: No
3: Build a new one. Here is how to create a ijl15.dll automatic inject dll(s).

#include"ijl15.h"

namespace ijl15{
    DWORD dwInit;
    DWORD dwFree;
    DWORD dwRead;
    DWORD dwWrite;
    DWORD dwGetLibVersion;
    DWORD dwErrorStr;
}


void _declspec(naked) ijl15_Init(){_asm jmp dword ptr [ijl15::dwInit]}
void _declspec(naked) ijl15_Free(){_asm jmp dword ptr [ijl15::dwFree]}
void _declspec(naked) ijl15_Read(){_asm jmp dword ptr [ijl15::dwRead]}
void _declspec(naked) ijl15_Write(){_asm jmp dword ptr [ijl15::dwWrite]}
void _declspec(naked) ijl15_GetLibVersion(){_asm jmp dword ptr [ijl15::dwGetLibVersion]}
void _declspec(naked) ijl15_ErrorStr(){_asm jmp dword ptr [ijl15::dwErrorStr]}


BOOL ijl15::Initialization(){
    HMODULE ijl15;
    
    ijl15 = LoadLibraryA("autoinject/ijl15.dll");


    if(ijl15 == 0){
        Error("Couldn't load autoinject/ijl15.dll!", TRUE);
        return FALSE;
    }
    
    dwInit = (DWORD)GetProcAddress(ijl15, "ijlInit");
    dwFree = (DWORD)GetProcAddress(ijl15, "ijlFree");
    dwRead = (DWORD)GetProcAddress(ijl15, "ijlRead");
    dwWrite = (DWORD)GetProcAddress(ijl15, "ijlWrite");
    dwGetLibVersion = (DWORD)GetProcAddress(ijl15, "ijlGetLibVersion");
    dwErrorStr = (DWORD)GetProcAddress(ijl15, "ijlErrorStr");




    if(dwInit == NULL || dwFree == NULL || dwRead == NULL || dwWrite == NULL || dwGetLibVersion == NULL || dwErrorStr == NULL){
        Error("Couldn't find ijl15.dll's function!", TRUE);
        return FALSE;
    }


    return TRUE;
}




void ijl15::Error(char message[], BOOL kill){
    MessageBoxA(NULL, message, "ijl15.dll", MB_OK);
    if(kill == TRUE){
        ExitProcess(0);
    }
}
