I changes cores to fb_alpha, the one i use for arcade (csp1, cps2, cps3 and rest) but no luck.
Its realy strange because it worked before with fb_alpha_neo.
Maybe i should point out, before i set up Neo Geo an Arcade, i wanted to have Neo Geo,CPS1,CPS2 and Arcade as seperate platforms.
But when i tried to set up like that, launchbox could only launch my Neo Geo, CPS2 and not CPS1.
And when i changed to only Arcade, it launched everything without problems.
