Hi, i own 1942 on WiiVC. Shound a WiiVC category be created or subit as ArcadeEMU?

The WiiVC versions of 1942 have the NES and Arcade versions, so you can play/run these versions per separate. Obviously, you should show up and confirm that NES and Arcade runs are done in Wii Virtual Console. Therefore, an additional category won't be necessary if WiiVC can freely be suitable to run NES and also Arcade.
