Mortal Kombat 11: Aftermath — Update 1.0.17

Mortal Kombat 11: Aftermath’s Update 1.0.17 continues NetherRealm’s pattern of balancing gameplay, fixing bugs, and polishing presentation for the fighter’s extensive roster and story-driven expansions. This article summarizes the patch’s key changes, analyzes their competitive impact, and highlights what players should test next.

Should You Install Update 1.0.17?

Fixed a bug where some character towers would not load.
Improved online desyncs when playing against PC or PS4 players (cross-play is not fully supported, but netcode improvements help).

Installation Steps:

Merge Files: Place the Base NSP, Aftermath DLC NSP, and the Update 1.0.17 NSP onto your SD card (root or /install folder).
Open Installer: Use Tinfoil (v16.0+) or DBI (backend).
Install Order:
- Install Base NSP first.

- Install Aftermath DLC NSP.

Patch highlights

Major bug fixes affecting character interactions, move properties, and cinematics.
Balance adjustments for multiple fighters: frame data tweaks, damage scaling changes, and adjustments to special moves and combos.
Online improvements: rollback/netcode optimizations and matchmaking stability fixes.
UI and accessibility: menu fixes, language/localization fixes, and minor HUD adjustments.
Quality-of-life: reduced loading hitches, corrected trophy/achievement triggers, and fixes for Aftermath story/chapter progression hangs.

Is the Switch 1.0.17 Version Worth It?

While the PS5 and Xbox Series X run MK11 at 4K/60fps, the Mortal Kombat 11 Aftermath NSP Update 1.0.17 finally delivers a portable experience that is "good enough."

Pros: All DLC intact, functional Story mode, stable 30fps gameplay (60fps on character select screen).
Cons: Textures are muddy compared to current-gen; the Krypt still stutters slightly.

If you are traveling or play exclusively in handheld mode, version 1.0.17 is the gold standard.

Q4: Does this work on Yuzu Emulator (Steam Deck)?

A: Yes. Yuzu EA build 3600+ runs Update 1.0.17 flawlessly at 60fps. You must enable "Use asynchronous shaders" and set CPU accuracy to "Unsafe" for the cutscenes to render correctly.

Visuals

Dynamic resolution scaling has been relaxed slightly in Docked Mode (900p target down from 1080p, but more stable).
