No problem - here's what you'll need to do:
Since two menu screens would be best, we'll have to start a hierarchy.
- Open Atomic Studio
- Open your project
- On the right side, right-click on the screen that is there and select remove from hierarchy.
- Click on New Screen, select a menu to select emulators, click OK
- Give it a name (Main is fine - this won't show when Atomic starts up)
You should have a screen for Mame already on left, so we need to create one for Daphne:
- Click on New Screen, select a list of games to launch. Give it a name (LaserDisc, or Daphne - this will show up in Atomic, so choose something appropriate) click OK
- Choose LaserDisc for the emulator type
- Browse to the Daphne program for the emulator exe (daphne.exe - not the loader)
- Browse to the Roms folder
- Browse to the Snaps folder and then click OK
Now we need to configure the Daphne Screen:
- Right-click on the Daphne Screen and select Define Exceptions.
- Select one Rom at a time and under the command line option below, point to the corresponding batch file for each of your Daphne games that you already use, which is probably easier for you since you already have the command lines with switches, or just put the actual command line in there.
- Repeat for each Rom.
(Normally, you would just put a command line with switches, which is why you can't browse to a file here.)
Now we can build the hierarchy:
- Drag the Main screen to the right
- Drag the original mame one you created from before on top of the main one. It should indent to the right to indicate it's a sub-menu
- Repeat for the Laser screen
Save your project:
- Click the Save Project button on the left
- Click the Activate and Run button to test and see if it works properly.
Let me know if I missed something (going mostly on memory) or if it doesn't work correctly.
