Slot-Brick 0.50 Brings PlayStation Support and Its Own Experimental OS

Version 0.50 of Slot-Brick is out, introducing PlayStation support, expanding hardware compatibility, and adding Slot OS, an experimental custom firmware option that allows the handheld to boot directly into the Slot-Brick frontend.

I’ve covered Slot before, but this is my first time writing about Slot-Brick. If you’re wondering what the difference is between the two, you’re probably not alone.

Slot is Brandon T. Kowalski’s original frontend, developed for Anbernic’s RG SP handhelds. Slot-Brick is an unofficial adaptation for TrimUI’s Brick family of handhelds. While both share the same cartridge-based interface, Slot-Brick has taken things further with additional system support and features tailored to TrimUI’s hardware.

Now, if you’re keeping track at home, kids, Brandon describes the original Slot as “just a glorified wrapper around mGBA and gpSP.” So, if Slot-Brick is a port of Slot, does that mean we’re now double-wrapped? Just like your dad encouraged you to do.

PlayStation support represents another milestone. Rather than attempting to fit disc-based games into the existing cartridge interface, Slot-Brick introduces a dedicated shelf where PlayStation discs spin into a virtual disc slot. The new functionality uses PCSX ReARMed and supports games with multiple discs. It’s an interesting addition that reminds me a little of Socket, another frontend that embraces the nostalgia of physical game collections.

Perhaps the biggest development is Slot OS, an experimental custom firmware option that allows the Brick to boot directly into the Slot-Brick frontend without first loading the stock firmware interface. According to the developer, startup is considerably faster than the traditional installation method. Slot OS runs from a microSD card and does not replace the handheld’s internal firmware. For now, the developer recommends the traditional installation method, as Slot OS remains experimental.

Version 0.50 also introduces Brick Pro support, alongside the existing Brick and Brick Hammer compatibility. The developer has adapted the controls and lighting for the additional hardware, although the dedicated Brick Pro Slot OS image remains experimental and has not yet been tested on physical hardware.

Beyond these major additions, Slot-Brick continues to refine its interface, game library management, and customization options. What began as a Game Boy-focused frontend now supports six gaming platforms and offers its own experimental operating system.

Nostalgia is great and all. I’m a sucker for the old days myself. Simpler times, when physical media ruled, certainly had their advantages and disadvantages. But are we starting to oversaturate the nostalgia market with all these options? Slot, Slot-Brick, Socket. What’s next? Socket-Brick with Kung Fu Grip?

If you’re like me and regularly experiment with different custom firmware and frontends, there’s some good news. Slot-Brick can be installed on a separate microSD card, so you don’t necessarily have to abandon your existing setup. For example, I currently use SpruceOS on my TrimUI Brick, but I can prepare another card for Slot-Brick and switch between the two. Just remember to shut down the handheld before swapping cards, and back up anything important before formatting.
