Had fond memories of this kernel from my DSTT clone. Gave my old DS to my daughter and picked up a r4isdhc "2016" gold for cheap on a certain site that GBATemp promotes. It's a decent, speedy cart, but EGADS! The menu! Finding a game in a list of more than a dozen or so was painful.
Then someone told me you could install this alongside the original card soft, but you'd have to also boot into Ysmenu every time. But looking at the "multimedia_path.ini" made it seem that you could boot any .nds file from the "multimedia" icon, and I didn't get this thing for movie playback, so I changed it to ysmenu.nds. Quick and easy launch into a much better (and it seems more compatible with homebrew) system.
Thanks, RetroGameFan, for all your hard work. It truly is appreciated.
