A7800 emulator

[d8thstar]

i had this working, had a bit of an issue and have been rebuilding some things.  i'm using A7800 specifically for lightgun games.  from a command line, this works:

a7800 a7800 -joy1 lightgun -cart "D:\ROMS\Console\Atari 7800\Alien Brigade (USA).7z"

within LB, this does not and I can't figure out why.

a7800 -joy1 lightgun -cart

i've tried all the different combos of the tick boxes.  i'm stumped!

Can you share a screenshot of your emulator settings (in LaunchBox)?

The main Details section and the Associated Platforms section.

you know, sometimes it just takes venting the issue and someone responding to finally figure where the issue was.  it was my associated platform, i had "a7800" one too many times on the command line.

thanks and apologies for the waste of time

if i may ask...  cant get A7800 to exit with back+start but it is set correctly in LB...  i even tried resetting the button presses...

It should Just Work©.  The emulator is a derivative of MAME and pressing Escape on your keyboard will exit it.  Which is what "Exit Game" is 'pressing' via the controller.  I presume the controller Exit works with stand-alone MAME?

Make sure you're pressing/holding the buttons in that order.

Last resort:  add a Running Script

$Esc::WinClose, ahk_exe {{{StartupEXE}}}
