Shell Commands

[Kris_Perry]

That's a really good question, I thought I'd scour the leappad forums here and compose a list.

Are there any special tools for testing and debugging?

[hide]This method has only been tested on the LeapPad 2, but the Ultra uses the same test tools, so it should work on that as well.

First you will need shell access, then you can use the following commands:

touch /flags/no8sec
echo "/LF/Base/MfgTest/LaunchMfgTest.sh" > /flags/main_app

Restart the system and it should boot into the test menu. To boot normally again, choose the disable option in the test tools menu or simply run these commands via shell

rm /flags/no8secs
rm /flags/main_app

This will spit out a list of apps you have installed

cd LF/Bulk/ProgramFiles
grep "Name=" */meta.inf

Disabling the startup delay, copying an app to Main_App and listing files.

Since I suffer from CRS (Can't Remember Stuff) here are some things to do at the console:

1) Developer mode - On/Off
touch /flags/developer
rm /flags/developer

2) Keep AppManager from booting - On/Off
touch /flags/main_app
rm /flags/main_app

Number 2, as it turns out, will boot whatever you choose to put in the file "main_app".
The nice feature about #2 is, it stops the darn thing from continually shutting off as
it is prone to do when you want to fool with it. It basically just shows the splash screen.

Might I also suggest just running MfgTest directly with
./LF/Base/MfgTest/LaunchMfgTest.sh
or
./LF/Base/EmeraldMfgTest/LaunchMfgTest.sh
That way you don't have to worry about rm the flags XD

You can also load swf files directly with the following command (Works with Explorer, GS, Ultra)
./LF/Base/Flash/bin/saplayer <flash file>

If I've missed any feel free to add/quote them below!
