When creating a new folder, user should build a .prg file with the same name as
this folder. In our example above "prg1.prg" would be contained within a folder on the
SD card called prg1. The user must list all ILDA files under this folder to the .prg file.
The edited playing speed represents the speed in "ILDA mode". For example, user can
create an "aurora.prg" under the folder of "aurora".
When user adds new ILDA file to this folder, he should also edit this ILDA file to
the PRG file. In this way, user will find this ILDA file under "ILDA mode", and can set the
play speed.
