Heres a tip im hoping will help you and anyone else in the same boat!
When u get to a trigger point and have to press
or
u have to make sure when u press it the screen vibrates and u will see big white/transparent JP writing in the background, this indicates u pressed the trigger! Sometimes when an achievement pops up when u have to enter a trigger the trigger wont indicate so u miss it out.
Also make sure after every playthru u unlock a new "clear ending", which will be a new picture in the "Clear" section of "Extras". I checked everytime and twice a new picture didnt show up so I knew that I did something wrong with that playthru!!
Heres what I did on playthru 8:
01 Played it exactly like above.
02 After 7th trigger has quick saved, go into in game options with
03 Go into "Quickload" and highlight your newest save.
04 Press
on new save and it will turn
green.
05 Press
to exit out, select the left option both times.
06 Keep playing like normal.
07 After 12th trigger has autosaved, go back into options with
08 Press
on the 5 trigger saves after the green one.
09 Now quick saves for triggers 7-12 should be highlighted
green.
10 Press
to exit out, select the left option both times.
11 Keep playing like normal & complete the game.
12 From title screen go into "quickload"
13 Select the 1st
green quicksave(trigger 7).
14 Select the left option
15 Now press
on trigger seven.
16 Hold down
till cheev pops and u get to the next trigger point
17 Let it quicksave(although probably not needed, but doesnt matter)
18 Exit out into the main menu.
19 Repeat steps 13-18 for each next green quicksave
20 Work in the proper order
21 When u get to do the last one(12th trigger quickload) press
when u should and then keep playing and complete the rest of the game!
More achievements & a gamerpicture will unlock along the way!!!
