Tails7 is a project I've been developing since 2025; its goal is to replace the outdated Mode 7 Ex extension from the early 2000s with a modern engine that performs better on newer hardware.
Tails7 uses shaders to render the ground and polygons; wait, polygons?
- Yes, Tails7 has a built-in example of simple polygons, but they are limited in terms of how points can be placed for the polygon to render correctly.
This engine is designed to be ported to other runtimes; it currently supports Windows, Android, iOS, and macOS; (note that a platform-specific DLC is required to port the game).
What if the GPU doesn't support shaders or supports them with limitations?
- Windows:
- When the game is rendered by the CPU (DIB), a memory leak may occur due to the massive scale of objects, also Ground Render and Polygons are invisible;
- When the game is rendered using Direct3D 8, objects that require shaders will be still invisible (Ground rendering and Polygons), but no memory leak.
- You can use Direct3D 8 (not recommended) for partial functionality, and for full support use Direct3D 9 or Direct3D 11.
- Android, iOS and macOS:
- Not yet tested.
In terms of "modularity", Tails7 relies on "modes" to determine how to calculate mapping, position objects on the screen, calculate distance, scale, rotate, etc. It's easy to add your own new mode.
- The latest stable release is R1.0.2_29.11.25;
- The latest preview release is R1.0.3_22.06.26a (Recommended for use);
- This description was last updated on July 3, 2026;
- You can find the tech demos on Itch.io
- (the code is terrible, but it shows off the engine's capabilities)
- Do you need the documentation?
- here's the link.
I would like to sincerely thank them because the project would not work out:
- Sketchy / MuddyMole
- Linky
- Glace Sue
- Clickteam
- KYwoo
- PsichiX
- NaitorStudios
- Clickteam Fusion 2.5:
- Link to the standalone version;
- Link to the Steam version;
- Required minimum Fusion build: 296.9;
- Tails7 requires that you have the "+" Fusion DLC; without it, you'll get an error when launching MFA:
- The project must be set to Direct3D 9 or Direct3D 11 Display Mode! Otherwise, the calculations will not work!
- Basic knowledge of how to use Clickteam Fusion
- Foxioo Shader Pack is installed
Installation process
1. Press Code -> Download ZIP.
2. Choose the folder where you want to download the entire zip file.
3. Open the folder where the Tails7 zip file is located.
4. Extract the Tails7 zip file.
5. In your browser, now go to the GitHub page of the FSP package (If you have FSP installed, skip to point 9).
6. Also click Code -> Download ZIP to download the shader pack that is needed for Tails7.
7. In Clickteam Fusion, go to Tools -> Windows Explorer, a window should open showing where Fusion is installed.
8. Move the **Foxioo Shader Pack** folder from the zip subfolder to the Effects** folder where Fusion is installed and restart Fusion.
9. Return to the folder where you downloaded the project and open Tails7.mfa.
10. When Tails7.mfa opens in Fusion, run the Runtime.
11. Congratulations! You have successfully installed the engine and can start working on your project/game!
