sampcac-loader

Bypassing SAMPCAC's protection of the samp.dll module in a very hacky and basic way.
This project is meant for people who want to use the SAMP-UDF in their Autohotkey application.

---

Usage

First you need to copy the following code in your Autohotkey application BEFORE you include the SAMP-UDF.
❗ The sampcac-loader.exe and sampcac-loader.dll have to be in a folder called dll
❗ If you want to use another path or other file name then you have to modify and build the sampcac-loader yourself.

global sampcac_mode := false
global sampdll_base_address := 0

WinGetTitle, gta_title, ahk_exe gta_sa.exe
global gta_title

WinGet, gta_process, ProcessName, %gta_title%
WinGet, gta_path, ProcessPath, %gta_title%
WinGet, gta_pid, PID, %gta_title%
gta_folder := StrReplace(gta_path, gta_process, "", "Off")
Loop, Files, %gta_folder%*, F
{
    if (RegExMatch(A_LoopFileName, "sampcac") && A_LoopFileExt == "asi") {
        msgbox, 0x40044, Loader, sampcac found!`nDo you want to start with sampcac mode?
        IfMsgBox Yes
            init_sampcac()
    }
}

init_sampcac() {
    global
    sampcac_mode := true
    Run *RunAs %A_ScriptDir%\dll\sampcac-loader.exe
    sleep 5000

    FileReadLine, sampdll_base_address, %gta_folder%\samp.dat, 1
}

If you have your own SAMP-UDF or something similiar then you have to modify it in order to get this bypass to work.
Replace the following functions in your SAMP-UDF or copy and paste the additional code.
❗ Skip this step if you use the SAMP-UDF from the example

refreshGTA() {
    newPID := getPID(gta_title) ; <--- modified
    if (!newPID) {
        if (hGTA) {
            virtualFreeEx(hGTA, pMemory, 0, 0x8000)
            closeProcess(hGTA)
            hGTA := 0x0
        }
        dwGTAPID := 0
        hGTA := 0x0
        dwSAMP := 0x0
        pMemory := 0x0
        return false
    }
    
    if (!hGTA || (dwGTAPID != newPID)) {
        hGTA := openProcess(newPID)
        if (ErrorLevel) {
            dwGTAPID := 0
            hGTA := 0x0
            dwSAMP := 0x0
            pMemory := 0x0
            return false
        }
        dwGTAPID := newPID
        dwSAMP := 0x0
        pMemory := 0x0
        return true
    }
    return true
}

refreshSAMP() {
    if (dwSAMP)
        return true
    
    ;applying bypass
    dwSAMP := sampcac_mode ? "0x" + sampdll_base_address : getModuleBaseAddress("samp.dll", hGTA)

    if (!dwSAMP)
        return false

    versionByte := readMem(hGTA, dwSAMP + 0x1036, 1, "UChar")
    sampVersion := versionByte == 0xD8 ? 1 : (versionByte == 0xA8 ? 2 : (versionByte == 0x78 ? 3 : 0))
    if (!sampVersion)
    	return false

    return true
}

If you have applied everything correctly then you should be able to use everything that is provided in the SAMP-UDF.

Any questions or problems?
