How DemsPRO works

DemsPRO is a Windows FastFlag injector and FPS unlocker for Roblox. It patches memory directly: no DLLs, no drivers, no code execution.

Injection

Five stages take Roblox from launch to a live flag set. Detection and reapply keep running in the background.

  1. 1

    Detect

    Every 1.5 s the app scans for RobloxPlayerBeta.exe and opens a read/write handle to the process.

  2. 2

    Identify

    The exact Roblox version is resolved from the module path, the process image path, a memory scan for the version- token, or the registry.

  3. 3

    Resolve offsets

    Every Roblox update shifts flag addresses, so offsets for the detected version are loaded from the local cache or fetched. Unsupported versions are refused.

  4. 4

    Write

    Each flag is written at its offset as a 4-byte value: true is 1, false is 0, numbers are written as-is.

    Fallback chain
    1. NtWriteVirtualMemory
    2. VirtualProtectEx + retry
    3. WriteProcessMemory
  5. 5

    Reapply

    Roblox resets flags at runtime. While connected, the app re-reads each value every 2 s and re-writes anything that was reset.

Behaviour

Auto-Reapply Home · Settings
Runs the reapply stage above, so flags Roblox resets come back on their own.
Smart Mode On by default
Attaches and injects the moment Roblox is detected. No clicking required.
Self-cleaning
Flags with no offset for your version, or with unparseable values, are removed after a failed write so your list stays valid.
Persistent
Your flag set is saved to %LOCALAPPDATA%\DemsV6\flags.json and restored on every launch.
Shared output
The live injected set is mirrored to %LOCALAPPDATA%\Demstrand\injected_flags.json for other tools to read.
FPS unlocker
Sets DFIntTaskSchedulerTargetFps directly and removes it from your flag list so it never conflicts with the editor.
Kill switch Flags tab
Force-closes RobloxPlayerBeta.exe in one click. Useful after a crash or a bad config.
Profiles & presets
Swap complete flag sets from community profiles or your own presets, replacing or merging.

Security

Antivirus may flag DemsPRO

Any tool that opens another process with write access and patches its memory looks like an injector to heuristic engines. That is exactly what DemsPRO does, so generic detections (HackTool, Injector, heuristic “Trojan”) are expected false positives. Nothing is injected or executed inside Roblox; the app only writes plain 4-byte values to known offsets.

What DemsPRO never does

  • No DLL injection, remote threads or shellcode. Only integer values written to known flag offsets.
  • No kernel drivers, services, installers or permanent system changes.
  • Nothing is written outside Roblox’s memory and the app’s own JSON files under %LOCALAPPDATA%.

Troubleshooting

Windows SmartScreen shows “Unknown publisher”

Builds are unsigned, so SmartScreen may warn on first launch. This is expected and not a threat.

My antivirus quarantined the exe

Add an exclusion for DemsV6.exe. Each build has a stable hash.
