I haven't seen this anywhere, so i am going to throw this out there.
This is how i organized my 1.0 eboots, i have converted ALL of my eboots to 1.0 and they all work great.
it will allow you to edit the date of files/folders (Windows only).
the psp organizes your games by the date of the folder that is it in.
so in windows, i displayed a detailed view in my games folder and right clicked on each one in reverse order clicked the edit date option. then i clicked the now button to set the time on the folder.
if done in reverse order, they will display in the correct order when you view them on your psp.
