0.129u3: Angelo Salese improved the sound in Double Wings by appling the same handling of Night Slashers (they are actually similar if not same memory map). 0.128u4: Angelo Salese fixed several protection issues with Double Wings, improved video and sound. Added 'Territory' dipswitch. 21st November 2008: Angelo Salese - Looking at Double Wings protection, first of all to fix the protection jump vectors in it. Protection works in a easier way than expected, to say in the simplest words I can use it's a "fan type jump vectors" (i.e. only a few possible results are expected). 0.126u4: Fabio Priuli added DIP locations to Double Wings. 0.106u3: Brian Troha, Guru and Yasuhiro Ogawa updated dipswitches in Double Wings. These dips are read using the protection, thus they don't currently have the stated effect on the game as the protection is not implemented right now. Also the Original PCB showed the title screen in English, and the current implementation shows it in Korean(?), so it is likely there is a Language dip/jumper setting. Added 'Coin A/B', 'Flip Screen', 'Lives', 'Difficulty', 'Bonus Life', 'Allow Continue' and 'Demo Sounds'.
