Details

This patch allows you to open any bitmap
backdrop size or smaller and display it.
It wil display a random 2 digit password
before the image. To exit select power
on the sansa and enter the password.
Use select on the sansa to exit without
a password (backdoor)
Just a proof of concept for password protection.
You could make a WPS screen to display.
select a bmp and use open with to set the config file
and then run the plugin.

Reason for closing:  Rejected
Additional comments about closing:  totally pointless because resetting the player or even plugging in usb is enough to get round this.
enabling party mode is more likely to stop people fiddling than this.

"Nice" password protection, if I press power it asks for the password but if I press select it quits without asking. (Irony)

yes select is a backdoor.
Easy to lock it down, remove some code, but I forgot the password
so many times while testing I put in the backdoor.
The matrix_pass  FS#7920  screensaver has no backdoor.

Even without a backdoor, what's stopping someone resetting the device to access it? Don't know if the Sansa has a hardware shut down/reset, but many targets do...

This provides as much protection as a win98
password protected screensaver. This is only
to keep honest people from poking where they should not.
