Real genesis sound compare to deflemask sound. What is the best?

Hi,

I started using deflemask a few days ago. And I'm wondering : does the sound is really better on real hardware? I have a megadrive 1 and the everdrive x7 flashcard. So I listened what I did on deflemask on my megadrive 1, but I can hear a "hum" on the real hardware and some instruments are too long (this can probably fixed with note off)

These who use deflemask, do you generally record on real sega genesis/megadrive or export directly to wav via emulator?

I'm just talking about the sound quality, not about the cool thing of play it with megadrive. I didn't compare yet with my monitor sound system yet but I yould like to know what people usually do.

PS : I use deflemask on an ipad, it sounds very good
