TETRIS® THE GRAND MASTER 4 -ABSOLUTE EYE- News

Development Update: This is a technical update on our ongoing work.

This is a technical update on our ongoing work and recent reports we have received from users.

▼ Issue: Game Progress Being Reset (Reported by Some Users)
Some users have reported that their game progress appears to be reset upon restarting the game.

We would like to first provide a potential recovery method for those affected by this issue.

We have implemented a backup system within the game that stores up to 10 previous versions of save data.
These backups include progress information and option settings.

Backup location:
C:\Users\[YourUserName]\AppData\Local\tgm4\savedata\[SteamID]\backup

Files:

option.01.ini ~ option.10.ini

status.01.ini ~ status.10.ini

If your progress has been lost, please try the following recovery procedure:

Navigate to the folder above.

Choose the lowest-numbered backup file (e.g., option.01.ini, status.01.ini).

Copy and rename it to overwrite the current files in the following directory:

Save data location:
C:\Users\[YourUserName]\AppData\Local\tgm4\savedata\[SteamID]

Overwrite these files:

option.ini

status.ini

If the files still appear corrupted, try using the next backup in sequence.

Current Analysis and Findings:
To be fully transparent ? we do not yet know the exact cause of this issue.
We acknowledge the possibility that this could stem from a coding error on our side.

Based on the information provided by users who reported the problem, the following commonalities were noted:

The issue became noticeable after restarting the game.

Steam Cloud was enabled during the time of data loss.

Beyond these two points, we were unable to identify any consistent patterns.

We did, however, manage to reproduce a similar case internally under the following conditions:
After quitting the game, if Steam attempted to upload save data to Steam Cloud,
and the user closed the Steam client before the sync completed,
there were rare cases in which save data was lost upon the next launch.

We suspect that when the game tries to load the save data but finds it incomplete or corrupted,
it may treat the environment as if it were a first-time launch, and reset the data accordingly.

As a temporary and cautious countermeasure,
we kindly ask that players disable Steam Cloud for this game.

We are continuing to investigate the issue and working on a permanent solution.
We sincerely apologize for the inconvenience.

▼ Issue: Detection by Windows Defender (Trojan:Script/Wacatac.C!ml)
Some users have reported that Windows Defender flags the game as “Trojan:Script/Wacatac.C!ml.”

We have thoroughly checked the original code to rule out the possibility of an actual virus,
and we have found no malicious content or infection within the codebase.

We are confident that this is a false positive.

What is "Trojan:Script/Wacatac.C!ml"?
It is a broad, generic detection label used by Microsoft Defender to flag software that behaves “suspiciously,” even if it is harmless.

Script: Despite the name, this label can be applied to programs that do not contain JavaScript, VBScript, or any scripting at all.

Wacatac: Not tied to a specific malware family ? used generically for questionable behavior.

.C!ml: Indicates that the threat was flagged via machine learning algorithms.

We have already submitted a false positive report to Microsoft.

We will continue to monitor and investigate this issue as well.
Again, we apologize for the trouble and thank you for your patience.

Ver. 1.1.2 Patch Update Notice

This is an announcement for the Ver. 1.1.2 update.

※ Replay data from versions prior to 1.1.1 will remain compatible.

The following fixes and additions have been made:
Bug Fixes:
  • Fixed an issue where the “Replay” (Re-play) feature in certain option menus was not functioning properly
  • Corrected an issue with Hold-based placement guides not displaying properly
  • Fixed a problem in “Practice in Game Mode” where BIG Mino placement guides were not functioning


Changes:

  • Strengthened the custom backup process
  • For portrait-oriented screens, black borders will now be added to the top and bottom (stretch scaling has been removed)
  • If the configured monitor is not found, the game will now launch in borderless mode by default


As for the behavior during versus matches involving BIG Minos,
we are aware that it follows TGM series-style mechanics,
but since some players are perceiving it as a bug, we are currently evaluating the situation.

Ver. 1.1.1 Patch Update Notice

This is an announcement for the Ver. 1.1.1 update.

※ Replay data from versions earlier than 1.1.0 will no longer be compatible

The following fixes and additions have been made:

  • Added up/down arrow indicators in list-style menus when scrolling is possible
  • Corrected some Simplified and Traditional Chinese text
  • Adjusted fox character display
  • Added line clear visual effects
  • Added a “Retry” option to the pause menu in Game Mode Practice
  • Fixed a code error in the Diagonal Down option introduced in the previous update
    ・Adjusted related input behavior
    ※ Replay data from versions earlier than 1.1.0 will no longer be compatible

Additions:
  • Fixed an issue with the medal settings for MASTER mode in the “Practice in Game Mode” settings menu


Experimental Changes:
  • Began testing a response to false positives from antivirus software (disabled obfuscation)
  • Even if AVX is not detected, users can now choose to proceed after a warning message
    Please note: the game may still crash afterward; this implementation is experimental

Additional:
  • Began testing behavior during fullscreen mode


Thank you for your continued support.

Development Update: Upcoming Update Ver. 1.1.1

Development Update: Current Status Report

Here is the latest report on the current situation.

  • DirectInput Issue
    Similar to the AVX issue, this game does not officially support DirectInput.
    While we are not removing support immediately, we kindly ask users who are using DirectInput devices
    to switch to Steam Input if possible.

  • AVX Issue
    Currently, we are testing AVX-only systems (without AVX2) to allow the game to run,
    but this is causing performance issues for some users on AVX2-capable systems.
    Given that there is nearly a 4x performance difference in processing capability,
    it is difficult to continue supporting both environments equally.
    We kindly ask users to consider upgrading to AVX2-capable hardware if possible.

    Additionally, Mac and similar platforms are not officially supported.
    Attempting to support these systems through forced detection could be risky and unstable,
    so for now, we are releasing the game with the understanding that it may not run on such environments.
    We plan to conduct further tests when the timing is appropriate.

  • Spoiler Issues Due to Unauthorized Activity
    We’ve observed that spoiler content from game data analysis is being spread
    through community forums and external sites.

    As previously stated, we have no intention of restricting discoveries made
    through players' own legitimate gameplay and skill.

    However, data mining and reverse engineering diminish the value of the product?
    and more importantly, they can also undermine the achievements of skilled players,
    which is deeply disappointing.

    At the very least, we kindly ask that such unauthorized spoilers not be posted on this community board.


Thank you for your understanding.
