I installed it using the Maemo Extras-Devel. if you just wont install these apps then: Open aplication manager and add a new application catalogue and type exactly as follows. Catalogue name : maemo extras-devel web address : http://repository.maemo.org/extras-devel distribution : fremantle components: free non-free then save. Word of warning though this area is for testing and apps could brick your device. Also you have to install zeemote before you can install drNokSNES. Just use the search function in the app manager.
