so you think guys are cute? 
only kidding. hyperspin is pretty nice. i plan on sticking with it. i dont know anything about your generic wrappers. will this make nebula work in hyperspin for neo geo cd?
Hyperspin is the front-end... it has nothing to do with the emulator and very little to do with the launch method. I don't use hyperspin, so I don't know for certain if they will work but if HS is programmed correctly they should work... you launch one of them as you would launch the emulator. You'll have to set it up for nebula though... which will take some time, but unlike writing a ahk script no programming knowledge is necessary.
I'm not making fun of you or picking on you btw... it's just that some HS users have sort of become the mac user of the emulation world.... everything is spoon fed, so when something goes wrong they don't know how to deal.

Strictly speaking though, nebula doesn't even need any help... it's a command line app. You just need to set it up by defining a rom directory and re-mapping the "quick exit" key to escape or whatever. It'll launch just like mame. So basically, no script or wrapper needed, you just need to actually set it up.

I would give you more specifics, but to be honest I haven't messed with nebula since around 2005.... as I said, arcade and cd versions are pretty much identical, so I never bothered.
I Hope that helps.
