Alright, since i didn't find much doc about that, here is the thing :

Normally, apps are automatically defragmented by the TI-OS when deleted.
However, that's not the case when they are deleted by a user program or app using _deleteapp (it just marks the app as deleted, $00 at 1st byte of 1st page).
Now, let's say i want to code a routine that will defragment the apps area.
In the case i have to erase page $68 or $69 (or both), i will of course have to erase the whole sector.
The thing is, that will include pages $6A & $6B (described as "certificate list" in the SDK).
Anybody knows what kind of data those pages are supposed to hold ?
Of course, i intend to restore them after the erase procedure, but is erasing them a problem ?

Nobody knows. The only thing BrandonW knows about it is that the OS will preserve any data in there when defragmenting apps. Since the OS does it, you should do it too---after all, something like zStart might decide to put something there.

Deleting it probably won't cause any problems, except for things that do weird hacks.

Ok...
I had to ask, since wabbit says those 2 pages are empty...
I just hope it is not supposed to include such infos as app locations, cause that would mean i'd have to update that stuff, and i'm definitely lazy about that =P
