They currently run with the DS-mode BIOSes and backwards-compatible touchscreen mode, but at the 133MHz clock speed and with 16MB of RAM. melonDS is an open source Nintendo DS(NDS) emulator. melonDS is part of a second wave of DS emulators. There are a few other emulator projects that are part of it, which you might have already heard of. Either way, check them out!
