v1.7.4.2-hotfix · Oct 25, 2026

After the previous releases v1.7.4 and v1.7.4.1, the critical bug was discovered on 3DS and Wii platforms that makes some effects being invisible. The suitable builds were been replaced at the previous v1.7.4.1's page as other platforms weren't affected by this problem.

This post contains Nintendo 3DS and Nintendo Wii only builds, for other platforms, you can download packages at the main post here. Also, all the binaries had been updated at the main post to prevent users downloading faulty builds without knowlege of that.

Hotfix changelog for 1.7.4.2

3DS / Wii: fix TheXTech 1.7.4.1 bug where NPC death effects would not display incorrectly. (@ds-sloth, thanks to @Wohlstand for the report)

v1.7.4.1 · Oct 18, 2026

When this update was supposed to be a small hotfix that fixes two small but annoying bugs, it also introduces the ability to use several graphics without cropping to original sizes. For example, BGO, some effects, terrain cells at the world map, scenery objects, and level points, now can have any size as big as you want. This only will work for levels and episodes are made for TheXTech. When playing episodes saved with old formats, they will have exactly same limits as before this update. However, objects of custom ranges will be expandable with no matter of the level or episode format.

EDIT: A Hotfix release 1.7.4.2 was out to address invisible effects bug on 3DS and Wii. Affected builds were been replaced in this post.

Known issues

Audio may be choppy on Old 3DS.
Texture load stutter is present on Wii.
The screen may slightly judder during section resizes on 3DS and Wii.
On 3DS, background texture may start to flashing. (https://github.com/TheXTech/TheXTech/issues/816) (Possibly solved, the primary reason of this is an out of memory).
On 3DS the crash happens on attempt to quit by the home menu. (https://github.com/TheXTech/TheXTech/issues/738)
On Windows 10 when running OpenGL with some ~2006 Intel iGPU on laptop, game would crash (possibly fixed).
On Windows XP SP0 that uses S3 Savage 4 video card is impossible to dynamically switch video modes: the game just crashes (blame video drivers by theme selves as they were always very bad, according to random talk of people from the 2000s (in Russian) ).
On Linux/Wayland, Window icon can't be changed while running game. (https://github.com/TheXTech/TheXTech/issues/939)
On Linux/Wayland, Mouse cursor doesn't gets unlocked from window on toggling windowed mode after fullscreen. (https://github.com/TheXTech/TheXTech/issues/937)

On iOS devices (iPhone 6S and newer that has the Taptic Engine equipped), when the tactile vibration is activated while playing using touch screen, the device might start to infinitely buzz at any random moment. To escape this problem it's need to switch from the game app to any other or to the main screen using home button or the home bar (depending on the device model) and wait when vibration will stop, and then, return to the game.

v1.7.4 · Oct 5, 2026

This is not a usual update. While it offers several bugfixes and features, it has three significant changes:

The first release with the official iOS and tvOS support!
Compiled Haiku binary releases are now available!
We changing the versioning model!

iOS and tvOS support

Since the foundation of the project of TheXTech it was never available at Apple mobile platforms such as iOS. And since this release it's now possible to build and install the engine on iOS-powered devices such as iPhone, iPad, and iPod Touch. However, this doesn't means the game app will be available at the AppStore. Instead it's available in a form of the IPA package that you need to install on your device using the Sideload method or build it from the source code using suitable Xcode kit on your Mac. All the details you can find at the TheXTech's Wiki documentation.

Haiku binary releases

Before this release it was a challenge to build the suitable CI image to automatise producing of binary release for the Haiku platform. And thanks to the Cross-platform Actions project, this became easy, and now TheXTech finally has the binary release for the Haiku operating system!

Versioning system change

The old format of versioning of "1.3.x.y" was a major problem for a while. It sets a lot of limits and prevents to properly release important hotfixes and let several package managers to properly handle them. Since this version the ".3." part of the version gets completely removed, and instead of "1.3.7.4" we are releasing "1.7.4"!

This is a minor hotfix for the 1.3.7.2 release that resolves an unexpected problem that occurs exclusively on 3DS, and might occur on Wii, and PSVita:

(Watch this video with a sound)

https://github.com/user-attachments/assets/fc8dd73f-6d64-4c27-a6ca-d6ba11d57b86

v1.3.7 · Jan 20, 2025

This is a large update. We worked long and hard on this update, and we finally ready to present this big update for you all! This update will be the biggest in TheXTech's history and features a huge set of features, bugfixes, and improvements.

Thank you to @0lhi who served on our core development team for design and quality assurance from version v1.3.4 (2021) to v1.3.7 (2025). His contributions are much appreciated.

**EDIT: A small hotfix for PortMaster has been released very soon: https://github.com/TheXTech/TheXTech/releases/tag/v1.3.7-hotfix1**

Most important changes

Widescreen and small-screen support, done right. No hacks, no editing luna.lua, no broken spawns. Play all of your favorite SMBX 1.3 content at your device's native resolution for a smooth and polished "remaster" experience, while the engine keeps track of which important items would have been onscreen (or offscreen!) in SMBX 1.3.

Classic playstyle for classic content. Disable TheXTech's unnecessary bugfixes and new features to play your SMBX 1.3 content the way its authors intended it, or go totally Vanilla (at your own risk).

An options overhaul. No more editing thextech.ini, every single game setting can be changed in the new in-game options menu.

Refined player select. A huge thank you to Savby for reimagining our text-based player select menus with an intuitive and colorful interface that feels right at home on your TV.

Multiple asset packs. TheXTech is good for more than just SMBX, and now you can conveniently switch between asset packs within the engine itself. Just add your extra asset packs to the assets subdirectory in your TheXTech folder, and switch by holding select at the main menu.

Beta 4P support. Ever wanted to play Battle Mode with 3 of your best frenemies? Now you can! This version introduces shared and split screen 4-player co-op and split screen 4-player battle. Please share your feedback and experiences with us so we can make it better!

Edit 2024-11-02: the included source package will fail to build for an arm64 Linux target (#855). Tag v1.3.6.6-1 fixes this issue.

Source code: Important note

If you want to obtain the source code pacakge, please take one of three archives named thextech-full-src-v1.3.6.6. Don't download the default source package as it will miss submodules. And because of that, it's unbuildable.

Edit 2024-11-02: if you are building for arm64 Linux, your build is likely to fail due to an incompatible ASM file mistakenly included in the build. As a workaround, you can modify 3rdparty/AudioCodecs/libopus/CMakeLists.txt. Replace the line if(OPUS_ARM_ASM AND CMAKE_COMPILER_IS_GNUCC) with if(0). See #855 for details.

v1.3.6.1 · Oct 14, 2023

We worked on this update long and hard, and now we're ready to present a bunch of new features and fixes! This is a checkpoint release after which there are major works will be started. But don't worry, if any issue occurs with this version, hotfixes will be released.

This is the first version that introduces true kind of internationalisation: now it's possible to have game being translated into many languages, including translations for episodes! (to translate episodes, the not-yet-released Moondust Translator component is required).

This update introduces the experimental OpenGL rendering that brings back the bitmask render (which is required to accurately reproduce the glitchy colours rendering of some levels that do use bitmask render for tricks).

Note: The rest of assets packages had been updated to add new directories fonts and languages that contains new fonts that allows to print non-ASCII characters, and some translations for the engine (currently, Russian and Chinese [both Simplified and Traditional] translations are available at this release, and other incomplete translations are available at the official repository). You may want to contribute to the translation process using the WebLate platform. A new file called editor.ini has also been added to enable customization of the in-game editor's features and is now required to use the editor.

Most important changes

Added real kind of internationalisation: fonts are able to print non-ASCII, TTF support, and multi-languages support. The game since now can be translated into other languages. This update makes TheXTech being a first branch of SMBX that features native multi-language support. While SMBX being English-only all the time, gives a lot of limitations to the whole world: a lot of people just don't know English, and the multi-languages support will get them to better understand the game and much easier get into it!
Experimental OpenGL support that allows bitmask render to bring back the support for colour tricks that were used at several vanilla levels and episodes and packed games (for example, "Reign of the Gatekeepers").
Added Homebrew Switch support. The game is now able to work on hacked Switch consoles or on emulators such as Yuzu.
Updated SDL2 and MixerX libraries. There are more game controllers got supported, and the support of existing controllers had been fixed somewhere. Now the game supports new music formats such as WavPack (wv) and PXTone (ptcop and pttune).
Added opt-in Discord Rich Presense support for these players who want to tell more about the game that they play. It's disabled by default, and you can enable it by editing of the settings/thextech.ini file.
The keyhole framerate fix now enabled permanently. That means, if you run an episode for speedrun, pay attention that keyhole exit will add 192 ticks instead of 300 as it was originally. The vanilla game used a different frame rate (100fps instead of 65fps) during keyhole exits which led to an inflated In-Game Time.
Various in-game editor features including the Magic Block automatic tiling mode, a first for the SMBX ecosystem!
Performance improvements that lower the game logic's CPU consumption on low-end systems.
