The TrimUI Brick Hammer just got a serious audio upgrade. Thanks to a new RockBox port running through MustardOS, this compact retro handheld can now double as a capable MP3 player with serious throwback appeal.
RockBox turns TrimUI Brick Hammer into a music machine
Music playback on gaming handhelds isn’t a new idea, but RockBox gives it a fresh spark. Through the MustardOS custom firmware, users can now load RockBox on the TrimUI Brick Hammer and enjoy a dedicated MP3 player experience with modern file support.
That means it’s not just playing MP3s. RockBox supports FLAC, ALAC, GBS, MOD tracker files, and even gapless playback. It works with the built-in DAC for clean sound and plays nicely with a range of file types most standard players ignore.
My Arcade launches two Pac-Man handhelds with five retro games and classic hardware to celebrate the game's 45th anniversary.
Easy setup brings RockBox to more than just the TrimUI Brick Hammer
The process isn’t locked to one device. While the TrimUI Brick Hammer takes the spotlight, other handhelds like the GKD Pixel and Anbernic RG35XX can also run RockBox using similar methods. Disco Disco Gaming’s YouTube walkthrough explains the steps clearly.
Users flash MustardOS onto an SD card, boot the handheld, then install PortMaster a small Linux port manager. From there, RockBox can be added and launched like any app. It’s a few steps, but nothing too technical.
MP3 player mods are making a quiet comeback
Dedicated music players may have disappeared from store shelves, but among retro handheld fans, they’re making a low-key return. This mod is part of that trend. For some, it’s nostalgia. For others, it’s about ditching phone distractions during music sessions.
Here’s what makes this mod appealing:
- Gapless playback and broad codec support
- DAC-based high-quality output
- Works on multiple retro handhelds
- Installation is simple with MuOS and PortMaster
- Free and open-source software roots
RockBox gives the TrimUI Brick Hammer new purpose
Bringing RockBox to the TrimUI Brick Hammer isn’t just clever, it’s useful. It makes the device more versatile without needing extra hardware. And with support for lossless formats, it’s far beyond a novelty.
Retro handhelds aren’t just about games anymore. Sometimes, they play the hits in more ways than one.
