Pessoal eu estava com o mesmo problema, o programa não abria, a tela ficava preta e dava a imprensão que ia abrir mas não abria, ai comecei abrir pelo terminal com o comando "sudo zsnes", porém o problema voltou mesmo abrindo pelo terminal, a impressão que tenho é que é porque fechei o programa maximizado, agora aparece as seguintes linhas no terminal:
