Atomiswave Games

A quick tutorial video showing how to set up Demul (Atomiswave) games to work with the Sinden Lightgun.

Tips

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 you have calibrated remove the gun from P2 in demulshooter.
If you have issues with offscreen reloading in games like Sports shooting USA make sure you are using the latest Demul version (DEmul v0.7 280418) older versions have broken reload mechanics.

Launch Script

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

NAOMI Games

The process for getting Naomi games to work is exactly the same as mentioned in the video above but with a few exceptions:

BIOS

You require the Naomi Bios's in your roms folders.

Launch Command

In the batch file you need to change "-run=awave" to "-run=naomi"

General Calibration

To calibrate the guns you have to enter the test menu with F4 and press F2 to cycle the selection, You need to go into the bottom "game test" menu to get access to the second test menu for the game where you can then calibrate them the same 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, You can use the normal MAME CHD's and these must be put in folders matching the rom name inside the ROMS folder.

Also all 3 of these games have a strange calibration screen that is not immediately obvious what you have to do.When you enter the calibration screen you will see something like this:

You will notice it has co-ordinates for Right, Left, Top Bottom and Centre.

Simply what you do when the cursor is pointing at right you click/shoot the right hand orange tab, Then press start button to go down to Left and click/shoot the left hand tab.

Repeat for Top, Bottom and Centre.

When you are done press start to cycle to Check and you should see a cross hair on your mouse.

I have noticed that it seems to move off the mouse a little as you got 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.

Once complete press F4 to exit and return to the test menu.

Ninja-Assault

The Naomi game Ninja-Assault uses a different, more complicated menu system to access the calibration. You can read more about it in the Ninja Assault page.

Launch Script

Example Batch (.bat) file:

Start D:\YOUR DEMULSHOOTER DIRECTORY\DemulShooter.exe -target=demul07a -rom=ROM NAME
