DeSmuME is an open source Nintendo DS emulator playable in Linux, MAC OS and Windows it is written in C++.Just like the title says though, is there a safe place where I can download an N64 emulator and won't get a virus? I went to this site called and I didn't download anything because I wasn't sure if it was legit. So I checked the sticky and it said it was cool to talk about this.Select Emulation and click on Run to start playing the game. NDS file (ds game rom) to open and click Open. Double click on the emulator exe to open it.
