Hello !
I found out how the "Movie Critic" achievement was stored.
Turn every 4 bytes from 0 to 1 starting from address 0x2886 until address 0x29CE (included).
It should look like this :
0x02880: FF FF FF FF FF FF 01 00 00 00 01 00 00 00 01 00
0x02890: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x028A0: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x029B0: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x028C0: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x028D0: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x028E0: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x028F0: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x02900: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x02910: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x02920: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x02930: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x02940: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x02950: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x02960: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x02970: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x02980: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x02990: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x029A0: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x029B0: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
0x029C0: 00 00 01 00 00 00 01 00 00 00 01 00 00 00 01 00
After that, trigger an ATE and it will validate the achievement.
Note that to test this out, I've left the first 3 ATE to 00 (first line, 0x02880), started a fresh game, and it validated after viewing the first 2 ATE of the forest.
So I ended up having the byte 0x0288E to 00, and it still validated the ATE.
That's why I think you can just turn them all on, and watch any ATE, and it should work.
If that's not the case, feel free to tell me.
