Introducing UInjectForge: A New Wii U Inject Builder

UInjectForge is my new application for creating personalized Wii U installable titles from your own game backups. It brings game preparation, artwork, runtime settings, building, and transfer tools into one workflow. If you arrived here expecting ZestyTS' UWUVCI, you're in the right place. This page now hosts UInjectForge.

Previously purchased ZestyTS' UWUVCI? Your purchase carries over to UInjectForge at no additional cost. You do not need to buy it again.

What Is UInjectForge?

Choose your console, provide your game and the required base or runtime, customize the artwork and settings, and build your title. UIF includes workflows for NES, SNES, GB/GBC, GBA, N64, NDS, GCN, Wii, TurboGrafx-16/PC Engine, and MSX. Requirements vary by system: some use compatible Virtual Console bases, while others need a separate homebrew runtime.

This is a new application, not another UWUVCI update or simply a new name for my old fork.

Why Build Something New?

After about six years maintaining UWUVCI, I wanted to take what I learned and build a different foundation. The goal wasn't just to change how the application looks, but to improve the process around making an inject.

• Native desktop builds:  UIF runs directly on Windows and Linux. The Linux version does not wrap the Windows application in a compatibility layer.
• A clearer workflow: Base/Runtime, Game, Artwork, and Build organize the process. Simple mode keeps everyday options accessible; Advanced mode provides additional control.
• Less file preparation: UIF accepts supported compressed game archives directly and handles split Wii WBFS files together when all parts are present.
• Built-in processing and packaging: Core disc processing and installable-package creation use UIF's own tooling, giving me more direct control over investigating and fixing those parts of the process.
• Storage and performance controls:  Choose where files are stored, check available space before building, and adjust performance settings to suit your machine.
• Batch builds and delivery tools: Queue multiple games, follow their progress, and use SD-card copying or network-transfer tools to move finished builds.
• Better troubleshooting information: Input checks, package validation, build-stage reporting, and exportable support bundles help identify where something went wrong.

My UWUVCI fork already improved parts of that experience. UIF takes the ideas further, with less dependence on a Windows-specific setup and a foundation that can support other platforms.

Availability and Expectations

Windows and Linux downloads are available now. macOS is planned next, with Android and iOS versions also in development. If you previously purchased the Mac version of ZestyTS' UWUVCI, your purchase still carries over. However, a macOS build of UIF is not included in this initial release.

Compatibility still depends on the game, base, runtime, and selected settings. Some advanced Wii/controller combinations need further hardware testing. PSP support is experimental and Tiramisu-only, while the separate Assistant and Aroma Bridge remain preview components. Package validation helps catch problems, but it cannot guarantee that every game will run correctly. You need a suitably configured Wii U and your own game files. Games, base titles, and keys are not included.

What's Next?

With V3.N2, I have retired from maintaining UWUVCI. I'm not retiring from Wii U homebrew development: UInjectForge is where I'm taking that work next, which is the secret project I mentioned in the last UWUVCI devlog.

Thank you to UWUVCI's contributors, everyone who supported my fork, and the single tester (you know who you are) who helped UIF reach this point.  Take a look at the downloads, try it with your library, and share what works well or could be clearer. Your feedback will help shape what comes next. If you come across a bug, please put it in a discussion post and provide as much information as possible. With everything being built from scratch and all of the possible permutations, I might have missed a few permutations.

Thanks,
ZestyTS
