No, this is currently not possible. What you are describing is a custom menu system. That's been requested many times before, but it is not currently implemented and I don't know where that is on Tom's priority list. On the other hand, I do have a suggestion that would be an interim solution. Rather than navigating to a menu for Nintendo, then selecting NES, then opening a game, you could have all of your Nintendo emulators listed next to each other. That would just require modifying the order you have your emulators set to (1, 2, 3, etc.). If you want to take it a step further, you could create an emulator called "-=Nintendo=-" that doesn't do anything and put it before the Nintendo consoles. Then, you could rename your emus to " NES", " SNES", " N64", etc. When they are listed in GameEx, they will show up like: -=Nintendo=- __NES __SNES __N64 (NOTE: The underscores are just for a place holder since the forum doesn't like leading spaces.)
