is it possible to take a screenshot with a r4ds ?

I wondered if it was possible to take a screenshot with my r4.
if there is an application I would like to now wich.
thx

I would like to know myself XDIf there was it would work on all flashcards

I really doubt it. It would have to be some new firmware, because the game would need to be loaded by whatever's taking the screenshots. I wouldn't be surprised if the CycloDS team put this function in their firmware at some point, but the R4 is dead.

It's not possible on any flash cart at this point.

There are screenshot hardware functions available, I think only 1 screen natively (modifications could be made). I heard they weren't very good though.
