Black screen when launching Demul's following arcade boards games via LB: naomi 2, hikaru, gaelco powervr2, sammy atomiswave

[vgbox]

...And if i cancel Game startup then Demul launches but does nothing.

The games launch perfectly fine when done directly through demul.

Only naomi games launch fine via LB.

The rom directories are the same in both LB and demul.

What would be the solution?

Thanks in advance

in the details tab of emulator, add this to Default Command Line Parameters:

 

-run=naomi -rom= -run=naomi2 -rom= -run=awave -rom= -run=hikaru -rom= -run=gaelco -rom= -run=cave3rd -rom=
