So the patch is done. It can be found here: https://mega.nz/#!yQ0B0ARA!7haRldyFs7Dz-Xxjd7MjxWAT6VhhY3BT5ZzFvy-GrvU
To apply the patch, simply drag the ISO file for the game onto the application as indicated. I’ll also be posting this link on the main Index PSP page.
EDIT: A number of people have reported the game crashing on real hardware. To fix this, under recovery menu, go to advanced and make sure the option “force high memory layout” is disabled.
