In the internal memory root folder you should have:
PRSPInstaller with some content (installer.sh and prsp folder with some stuff)
test-startup folder with startup.sh (you should get them from
this archive)
That's it.
PS
Just came to my mind, some of the earlier versions of boroda's firmware do not have this "launcher" feature, so get the latest version (which is 1.05k at the moment).
