@@ocult100 Fantomas is the legendary villain of French cinema. Many people remembered him for his impeccable disguise, purple skin and monotonously evil laugh. And Konami may not have intended Dullahan to look and sound like a Phantom disguised as him, but that's exactly what they did.
This video lacks bosses such as: Knight of the Order (Castlevania: Order of shadow), Dullahan and Edigore (Castlevania : Grimore soul). And if the latter is excusable (the servers of this game have been disabled for a long time), then the reason why you managed to figure out the PC-Engine emulator, but did not figure out the mobile phone emulator, is not clear to me.
