I don't own a Sega MD arcade stick, mostly because the ones that exist kinda suck.
What I DO have are Dreamcast arcade which I've slaughtered internally to put in DB-15 connectors, basically turning them into Neo Geo controllers. So if I load up an arcade-like title with MD core, say Alien Soldier, it would be nice if I could be using my Neo Geo style sticks to play the game.
