unfortunately, NB Rangers Returns is the ONLY osu! beatmap that emulates DJMAX Technika's gameplay. you'll have to do the beatmaps yourself if you want more. and based from my experience, making a Technika-emulating beatmap is VERY tedious job (the beatmap on the osu! teaser image i posted earlier took me 5 hours just to set up the timing lines).
if you're really determined to create your very own technika-emulating beatmap, download this pack

it's actually a technika chart simulator for flash, but it has some things inside it you'll find very handy, especially the image files.
