Emulator Problem: Emulators on Dreamcast?

Dear Readers,

Today I finally acquired a Dreamcast game system. I was wondering if it is possible to run emulators on the Dreamcast itself. I'm pretty sure you can by what ive seen looking around the internet, but there are no tutorials on how to run the emulators on the Dreamcast. If it is possible to run emulators on a dreamcast, can someone please either send in the right direction for a tutorial or tell me how to do it. I am looking a complete tutorial that will explain everything about emulation on dreamcast from square one. Thank you for your help.

So no one knows I take it?

Yeah it's very possible. I play NES, SMS, Atari VCS, Atari 800, Genesis and SNES on it all the time. In my opinion NES, SMS and Genesis emulation is the best. The others can be kinds stubborn to use and SNES emulation is very slow on most games with the exception of simple games like Mario World or Killer Instinct. NesterDC SE is by far the very best of them all IMO.
