Hi, I just got the Neo Geo fighting game bundle on sale, and I'm having issues with all the games that are using the DotEmu framework. None of them are recognizing my arcade stick, which is strange, since my PC is recognizing it with no problems, and it works fine with other games. Even Garou and Last Blade both recognize it with no problems, but for any of the Neo Geo titles emulated with the DotEmu framework, it's like it doesn't exist. I'm using a PS3 Hori RealArcade Pro stick, and running it on the SCPToolkit drivers. Like I said, it works just fine for other games, but the DotEmu titles are not recognizing it at all. Anybody else experience this/have ideas on how I can fix the problem?

The DotEmu ports seem to come with a whole barrage of problems. I didn't try this myself, but several community members have recommended using the open source emulator MAME to play these ports, relieving some (but not all) of the issues with these ports.
If I understood it right they extract the ROM form the GOG version and load it in MAME like they would with any other ROM.

Here's a detailed guide for playing these ports in OpenEmu which includes a description on how to extract the ROMs:

I'm sorry I can't be of more assistance, but I hope this post could at least give you some possible directions until someone more experienced comes along. Best of luck.
