A Comparison of TRIMUI Brick Hammer Firmwares
The TRIMUI Brick Hammer has quickly carved out a niche in the retro handheld community. With its premium metal shell and gorgeous screen, it’s a highly portable device with a fantastic feel. But to truly unlock its potential and turn this “metal brick” into a powerhouse, choosing the right custom firmware is absolutely essential.
Like its predecessor, the original TrimUI Brick, the Hammer benefits from a dedicated community of developers. They’ve created several excellent custom firmware options, each focusing on a different user experience: some are aiming for minimalist, pick-up-and-play simplicity, while others offer feature richness and deep customization.
Below, we break down some popular firmwares to help you decide which system is the best fit for your Hammer.
1. NextUI: The Power of Simplicity
NextUI is arguably the community's current favorite. It follows the philosophy of MinUI but delivers a faster, more modern experience.
- Experience: The interface is extremely clean, focusing simply on game lists and box art, cutting out unnecessary configuration menus and "bloat."
- Performance & Battery: Being lightweight, NextUI offers great performance and is renowned for its Deep Sleep/Suspend function. This significantly boosts the Brick Hammer's battery life, making it a true "pick-up-and-play" device where you just hit a button to resume your game instantly.
- The Catch: Minimalism means a lack of advanced features. It does not natively support RetroAchievements, so if earning digital trophies is a core part of your fun, you might need to look at other options or use additional tools to get partial functionality.
2.Knulli: The Feature Monster
Knulli is a custom firmware based on heavier systems like Batocera, and its goal is to provide the maximum number of features and customization options available.
- Experience: Knulli has a more "console-like" feel, running a full RetroArch backend. This gives you granular control over every emulator, letting you use features like Rewind, Fast Forward, and Game Achievements.
- Functionality: It often has native support for Wi-Fi and Bluetooth, allowing you to transfer files remotely via SSH or connect a Bluetooth controller (if the Hammer supports it). It’s also the better platform for PortMaster, allowing you to play more native Linux-ported indie games.
- The Catch: As a feature "monster," Knulli is inherently heavier than NextUI, leading to longer boot times. On the Hammer's modest hardware, you might encounter a few more bugs, and the battery drain will be higher.
3. StockMix: The Stable Compromise
StockMix is essentially the original factory firmware, but with crucial optimizations and community enhancements built in.
- Experience: It retains the layout and familiarity of the official firmware, making it the least intimidating option for first-time custom firmware users. There is no steep learning curve here.
- Functionality: It fixes common bugs from the pure stock version and incorporates useful tweaks, resulting in a smoother, more stable experience overall.
- The Verdict: StockMix is the well-balanced choice. If you aren't interested in deep customization and just want better stability and compatibility than the stock OS offers, StockMix is the most reliable upgrade path.
4.PakUI:Simple UI, Powerful Tools
PakUI takes the lightweight foundation of the MinUI lineage and builds a robust utility layer on top. The result is an experience that feels fluid and focused, but doesn't require you to compromise on modern features.
Key Advantages of Choosing PakUI
- Speed and Simplicity First: PakUI maintains a quick boot time and a clean, intuitive user interface, focusing on game lists and quick navigation. It still provides that satisfying "pick-up-and-play" feeling that NextUI users love.
- Integrated Feature Set: Unlike NextUI, where advanced features must be added manually as separate extensions, PakUI integrates them via the built-in Pak Manager. This makes enabling essential functions quick and seamless.
- Essential Modern Features: PakUI is an excellent choice if you require these common features:
- RetroAchievements Support: A huge draw for those who want to unlock digital trophies while playing retro games.
- Built-in Scraper: You can download game artwork and covers directly on the device using Wi-Fi (a massive quality-of-life improvement).
- PortMaster Compatibility: Easily access and launch ported indie games.
