Simply copy the 'data' and 'sprite' folder to your LF2 and copy these thing to your 'data.txt' in your 'data' folder.

id: 695 type: 0 file: data\template_ex.dat
id: 696 type: 2 file: data\template_ball.dat
id: 697 type: 3 file: data\template_ball2.dat

(the template require some .wav, but it won't be a problem if you're using normal LF2.)

Happy studying! ;3
