Will I see any difference from a class 4 SHDC card over a class 6 for edge (nds)

Hi.I ordered an edge so now I'm looking for a nice SDHC card. I found a nice 8bg one at low price but its only class 4. Will the emulator for my nds run games as smooth for a class 4 card as a class 6?Thanks for the help guys, I'm still new to all this nds emulation thing ;DP.S. If my question doesnt belong to this site forum at all, sorry about that.

Well, emulators shouldn't be compared to speeds of flashcarts/MicroSDs etc. Make sure to get Sandisk or Kingston brands, and you'll be fine.
