Currently I lack time to write an installation guide and so on. I hope you find your way with some effort. As Ken says in post #2, you might use the first posts of the "Kobo Start Menu 7" thread to get you started.
If currently KSM 07 is running on your device, it is sufficient if you install the KoboRoot.tgz of the KSM 08 package (with "handle update" > "install update" [do not use "install partial update"]). After KSM 08 is running, select "tools" > "activate" > "set runmenu settings.msh" > "always". You can then delete .adds/kbmenu in order to remove the now useless files of KSM 07.
If currently any KSM 08 test version is running on your device, please delete it before installing this version. You can find delete_KSM08.zip there.
Those files of KSM 08 that are located on the user partition are in .adds/kbmenu_user.
Selected topics:
Copy files from/to the system partition
USE THIS PACKAGE AT YOUR OWN RISK!
