Patch v1.11 — February 2026
Japan patch notes for version 1.11 — the stability update before v1.12, now baked into the Western release.
Disgaea Mayhem version 1.11 was released in Japan on February 26, 2026 by Nippon Ichi Software. It was the penultimate stability patch before version 1.12 in March 2026, and like v1.12, its fixes are incorporated into the Western build that NIS America shipped on July 23, 2026.
Western players do not download v1.11 separately — it is part of the cumulative Japanese patch history embedded in the international release.
Official Patch Notes
Nippon Ichi Software documented the following changes in version 1.11:
Crash Fix
- Fixed a bug causing the game to crash under specific conditions during normal gameplay (exact trigger not publicly detailed in English-language notes)
Visual Fix
- Fixed a bug causing green UI elements to display as grey under specific conditions — a colour-shift glitch affecting menus and HUD elements
Other Changes
- Fixed additional minor bugs not individually listed in the official announcement
Release Timeline Context
Version 1.11 arrived roughly one month after the Japanese launch on January 29, 2026 and one week before v1.12 on March 5–6, 2026. Together these patches represent Nippon Ichi Software’s pre-export stabilisation pass:
| Version | Date | Focus |
|---|---|---|
| Launch | Jan 29, 2026 | Initial JP/Asia release (PS5, Switch, Switch 2) |
| v1.11 | Feb 26, 2026 | Crash + colour bug fixes |
| v1.12 | Mar 5–6, 2026 | Fist skill crash + Item List crash fixes |
| Western | Jul 23, 2026 | Includes v1.11 + v1.12 fixes |
French coverage (JRPGFR) noted v1.11 rolled out on PS5 first, then extended to Switch and Switch 2 by late February 2026.
Impact on Western Players
If you launch Disgaea Mayhem on PS5, Switch, Switch 2, or Steam in July 2026:
- The grey-colour UI bug from v1.11 should not appear on an updated copy
- The unspecified crash condition patched in v1.11 should be resolved
- Any persistent crash on Western launch likely relates to unpatched edge cases or platform-specific performance issues rather than v1.11 bugs
For Fist skill and Item List crashes specifically, see the more detailed Patch v1.12 notes.
What v1.11 Did Not Change
Like v1.12, version 1.11 was a stability-only update:
- No weapon balance changes
- No Item World difficulty adjustments
- No new content, characters, or DLC
- No Cheat Shop parameter modifications
Build optimisations from the Tier List remain valid across v1.11 and v1.12.
Famitsu Reception Context
Around the v1.11 patch window, Famitsu scored the Japanese release 7/7/8/7 (average 7.2), praising power fantasy and gameplay loop satisfaction while not treating the title as a mainline Disgaea successor. Western launch reviews converged on similar themes — see Launch Reviews.

Frequently Asked Questions
Quick answers to the most common questions from Disgaea Mayhem players.
Do Western players need to install patch v1.11 manually?
No. v1.11 fixes are included in the July 2026 Western release build together with v1.12. Ensure your platform applied any day-one patch offered at launch.
What was the grey colour bug in v1.11?
Under specific conditions, green UI elements incorrectly displayed as grey. This affected menus and HUD colouration in the Japanese build before the February 26 patch.
Is v1.11 different from v1.12?
Yes. v1.11 (February) fixed a general crash and colour bug. v1.12 (March) added Fist skill combo and Item List crash fixes. Both are in the Western build.
Will NIS America publish English patch notes for v1.11?
NIS America typically publishes Western patch notes only for post-launch updates. Pre-launch Japanese patches v1.11 and v1.12 are documented here for reference.
