I'm running Ubuntu 16.04 lts on my laptop. I can run ZQuest just fine with no complications, but when I load up zelda classic and start my game link will only be moving down without pressing any keys. I have tried to swap the conntrols in all aspects and still can't get it to work. since I'm using the nes pallete link can only move in one direction. I can't test my quest because of this. I'm runing the linux release for 2.50.2. Thanks in advance for any help
