Kingdom Hearts Final Mix Platinum Guide (PS3, PS4)

PS3 / PS4

For Final Mix on PS4, decide which challenges to combine and which deserve a separate run. Proud covers difficulty, while Speedster, Undefeated and Unchanging Armor impose restrictions that can complicate a completionist playthrough. Do not copy PS3 playthrough counts: PS4 difficulty trophies stack. Then treat the journal, synthesis and Gummi Ship as separate collections, none automatically completed by defeating the final boss.

On PS3, Final Mix is part of HD 1.5 ReMIX. You need three clears at different difficulties and every Gummi blueprint. On PS4, in HD 1.5 + 2.5 ReMIX, difficulty trophies stack and 30 blueprints are enough.

Required difficulty: PS3: three clears. PS4: Proud also awards the lower difficulty trophies.
Missable trophies: Restricted runs require conditions maintained from the beginning.
Online: No multiplayer required.

On PS3, plan three clears and finish the Gummi collection

Set aside a Beginner save for the under-15-hour run with starting equipment and no continues. Use Final Mix for the journal, optional bosses and Gummi Ship work, and a third save for the Proud clear. On the collection save, track blueprints from Geppetto in Traverse Town, enemy drops and mission rewards in each world. Check the level 3 missions as well: they count towards the full PS3 collection.

Keep the three saves separate until the difficulty trophies unlock, and check blueprints in the Gummi menu.

On PS4, separate Proud from the restricted run

You can complete Proud for difficulty and prepare a more comfortable second run for time, equipment and continues. Combining everything is a personal challenge rather than a necessity for organising platinum. Label both sets of saves clearly; changing equipment in the wrong file compromises a condition not repaired at the final boss.

Distinguish Proud saves from the restricted-run saves.

Read exactly what must remain unchanged

Unchanging Armor concerns equipment, including weapons and accessories; do not confuse that with abilities or consumables. Undefeated concerns using Continue, so check the selected command after a defeat. Remind yourself of the restriction before a dedicated session; a normal completionist-playthrough habit can invalidate the run without an obvious warning.

Do not change weapons or accessories in the Unchanging Armor file.

Use the timed run for story rather than collections

Speedster requires defeating World of Chaos within 15 hours. A dedicated run is not the time to search for every Dalmatian or rare material. Prepare the world route and check time at major saves; looking only before the last encounter makes it difficult to identify where the available margin was spent.

Check the timer at saves before the concluding worlds.

Use the journal to identify the missing category

In the completionist run, compare Dalmatians, Trinities, reports and minigames in Jiminy’s Journal. A sealed world can still contain collections or optional challenges. Record the missing category before returning, distinguishing general exploration from targeted cleanup. Prepare optional bosses with appropriate abilities and items outside the speedrun’s restrictions.

Inspect the unfinished journal category before returning to a world.

Separate synthesis from Gummi blueprints

Synthesis Master concerns synthesised items, while PS4 Gummi Ship Collector asks for at least 30 blueprints. Keep separate material and route lists rather than applying the old PS3 all-blueprints requirement. Read each Gummi mission’s objective; clearing a route and satisfying a special mission are different actions.

Check PS4’s 30-blueprint requirement before hunting every blueprint.
