Load the new text document
Type the following command adjusting the drive/file path to suit:
Start C:\YOUR DEMULSHOOTER DIRECTORY\DemulShooter.exe -target=demul07a -rom=ROM NAME Start C:\nomousy directory\nomousy.exe /hide Start /wait C:\YOUR DEMUL DIRECTORY\demul.exe -run=awave -rom=ROM NAME Start C:\nomousy directory\nomousy.exe
Go to "File" then "Save As"
Give the file a name of your choosing, but it MUST end with .bat
For example, gamename.bat

Do the same for player 2's gun; if you are only playing with 1 gun, use your mouse to do this

- Some games require both guns to be calibrated; if you only have one gun, assign your gun to player 1 and player 2 in DemulShooter. Once calibrated, remove the gun from P2 in DemulShooter
- Offscreen reloading in games like Sports Shooting USA can have issues in older versions of Demul, make sure you are using the latest Demul version (Demul v0.7 280418)
Example Batch file text:
Start D:\YOUR DEMULSHOOTER DIRECTORY\DemulShooter.exe -target=demul07a -rom=ROM NAME Start D:\nomousy\nomousy.exe /hide Start /wait D:\YOUR DEMUL DIRECTORY\demul.exe -run=awave -rom=ROM NAME Start D:\nomousy\nomousy.exe
The process for getting Naomi games to work is exactly the same as mentioned in the video above, but with a few exceptions:
Place the Naomi BIOS files in your ROM folder.
Enter the test menu with F4 and press F2 to cycle the selection;
Select "Game Test" menu to access to the second test menu for the game
Calibrate the guns in the same way as Atomiswave games.
CHD Game Calibration
3 of the Naomi light gun games (Maze of Kings, Confidential Mission, and Lupin The Third: The Shooting) require CHD files. The normal MAME CHDs can be used. Put the CHDs in folders matching the ROM name inside the ROMs folder.
All 3 of these games have a strange calibration screen that is not immediately obvious what needs to be done. Entering the calibration screen, looks like:
It has coordinates for Right, Left, Top, Bottom, and Centre
When the cursor is pointing at the right, click/shoot the right-hand orange tab
Press the Start button to go down to the Left and click/shoot the left-hand tab
Repeat for the Top, Bottom, and Centre
Press Start to cycle to Check, a cross hair should be visible and matching the mouse cursor
The mouse moves off a little as you get to the extremes of the screen do not worry about this, though, as it does not seem to have any real effect on the games.
Press F4 to exit and return to the test menu.
Example Batch (.bat) file:
Start D:\YOUR DEMULSHOOTER DIRECTORY\DemulShooter.exe -target=demul07a -rom=ROM NAME Start D:\nomousy\nomousy.exe /hide Start /wait D:\YOUR DEMUL DIRECTORY\demul.exe -run=naomi -rom=ROM NAME Start D:\nomousy\nomousy.exe
