Complete guide to every feature in Go/No-Go Systems v1.3.9
Go/No-Go Systems requires no installation. Extract the zip file to any folder on your PC and run go-nogo.exe. Your settings persist across version upgrades automatically — just replace the exe when updating.
On first launch you'll see a trial notification. All features are fully unlocked for 3 days. After the trial, enter your serial key to continue using Go/No-Go permanently.
The main window shows:
Profiles let you create different configurations for different simulators or setups. Each profile has its own:
Use the Profile dropdown in the action bar to switch between profiles. The app list and COM ports update immediately. Your last-used profile is remembered across restarts.
Click the + button next to the profile dropdown. Enter a name (e.g. "DCS VR", "BMS Falcon", "MSFS") and the new profile is created and activated. Add your apps and COM ports for that setup.
Click the pencil icon next to the profile dropdown to rename the currently active profile.
Open Settings, scroll to the Profiles section in the General tab. Each profile has a delete button. You must always have at least one profile.
Monitor layout, kneeboard position, DCS paths, general preferences (language, splash, tray behaviour), and your serial key are global — they apply regardless of which profile is active.
/profile "path" on launchUse the up/down arrows in Settings to change launch order. Apps launch top-to-bottom during Go Flight.
Set one or more process names so Go/No-Go can detect if the app is already running. This drives the status badge (Running/Not Running) on the main screen.
The Go Flight button runs the full startup sequence in this order:
Closes COM ports first (to prevent driver issues), then stops all running apps.
Closes COM ports, stops all apps, and exits Go/No-Go completely.
The VR toggle button on the main screen lets you set whether DCS launches in VR or Monitor mode. It works by editing options.lua in your DCS Saved Games folder before DCS starts.
Click the VR button on the main screen to toggle between:
The setting is per-profile. Your "DCS VR" profile can always launch in VR while your "DCS Monitors" profile uses screens — no manual switching at the DCS splash screen.
Your DCS Saved Games path must be set (auto-detected from Settings, or set manually in the Kneeboard tab). DCS must have been run at least once so that options.lua exists.
Go/No-Go manages DCS-BIOS serial communication by launching the connect-serial-port.cmd hub process for each configured port.
Click Scan to auto-detect all connected COM ports on your system. Any new ports can be added in bulk.
The Comm Ports panel on the main screen shows each port as a coloured badge:
Click any badge to toggle that port on or off individually.
Click Hide Comm Ports / Show Comm Ports in the header to toggle the panel. Users who don't use serial hardware can hide it completely.
DCS updates sometimes overwrite custom Lua files and configurations. File Restore lets you keep your customised versions safe.
If you need to revert to the DCS version, click Undo Custom Script Changes on the main screen. This copies the DCS original back.
Click Check Custom Scripts on the main screen to manually check for modified files outside of the Go Flight sequence.
Windows can reorder your monitors after a reboot or driver update. Go/No-Go saves your exact display arrangement and restores it automatically.
After updating Go/No-Go, re-save your monitor layout once. The saved layout file is stored as JSON next to the exe or in a custom path you specify.
On multi-monitor setups, the DCS kneeboard often appears on the wrong screen. Go/No-Go lets you drag it to the correct monitor using a visual map.
A backup of the original DCS file is created automatically. A File Restore entry is also added so DCS updates won't undo your position.
Click Restore Original to revert to the DCS default kneeboard position.
DCS must be restarted for kneeboard position changes to take effect.
DCS compiles shaders and stores them in the fxo and metashaders2 folders inside your DCS Saved Games folder. Over time these caches grow large and can significantly increase DCS load times.
When enabled, Go/No-Go deletes the contents of both folders before each launch. DCS will rebuild them fresh on the next start.
The first launch after clearing may take slightly longer while shaders recompile. Subsequent loads will be faster.

When minimised to tray, right-click the tray icon for quick access to:
All features are fully unlocked for 3 days after first launch. No restrictions during the trial period.
Visit GoNoGo.Systems and click Buy Serial Key. Payment is a one-time $9.99 USD via PayPal. Your key is delivered by email.
GONO-XXXX-XXXX-XXXXYou may install Go/No-Go on multiple personal computers using the same key.
In Settings, click Export to save your entire configuration (apps, COM ports, file restore, preferences) to a JSON file. Useful for backups or transferring to another PC.
Click Import and select a previously exported JSON file. This replaces all current settings for the active profile. Your serial key is not affected by import/export.
This is registered as a global hotkey on startup. Useful when you're in the cockpit and need to access the launcher without Alt-Tabbing.
Log files are in the Logs folder (click the Logs button in the header to open it). Settings and license data are stored securely by the application.
If the restore fails after updating or changing hardware, re-save your monitor layout. The saved configuration includes hardware-specific identifiers that may change after driver updates or port changes.
The physical device is not detected on the system. Check that the USB device is plugged in and the correct drivers are installed. Open Device Manager to verify the port number.
Ensure your DCS Saved Games path is set correctly (auto-detected in Settings, Kneeboard tab). DCS must have been run at least once so that Config\options.lua exists in the Saved Games folder.
Check the Process Names field in the app's settings. This should match the process name shown in Task Manager (without the .exe extension). Some apps use different process names than their executable filename.
If the app crashed and your key was lost, simply re-enter it. From v1.3.9 onwards, settings are saved reliably and persist across all scenarios.
