Junkfood Custom Arcades (JCA) has launched a mini all-buttons controller for Super Smash Bros! Rumor has it that LBX stands for lunchbox, which goes along with the theme of the brand.

The LBX ships with JCA’s proprietary open-source GCC software, which is available to download and customize, but the LBX is compatible with other open source firmware as well. JCA suspects that there will be a few options made to work with their own hardware pinout. Needless to say, the LBX is tournament legal, and it has SOCD cleaning, preventing opposite directions from being registered simultaneously.


The LBX has the layout that Smashers have preferred as of recently and is undoubtedly reminiscent of the Frame1 and B0XX. Users of the aforementioned controllers should find themselves right at home.

The LBX comes standard with Kailh low-profile red switches but is also compatible with other Kailh Choc switches like the red pro or white. As for the custom black concave keycaps, they come standard on the LBX in addition to silencing pads being available on the store.

By default, the keycaps sound like you are typing on a keyboard, which you may have expected. The keycaps feel just fine and should not need an upgrade to be tournament viable, although you may prefer other switches.

You can flash Melee, ProjectM, and Ultimate modes right onto your LBX.


The robust LBX has plastic up top and metal at the bottom combined with an anti-slip pad. The weight is perfect for play on a table without compromising portability, the latter of which is even more convenient if you opt for the LBX pouch.

As for the custom PCB, it utilizes hot-swap sockets to make changing switches as easy as possible. If you opt for the separate Brook upgrade that should be available on the store, you would have standard console fighting game input options for the likes of PS and PC, but do note that soldering is required. You are six screws away from opening up the LBX if need be. Modding the LBX is possible but not particularly easy.

The USB port comes out of the back. Included is a braided USB-C to GCC cable that is six feet long. There is also a six foot USB-C to A cable for PC usage.


As the LBX is customizable, it can look as good as you want it to be. The material used makes almost any color scheme look good on the LBX. JCA made good use of the real estate, and the array of buttons given the limited real estate is pleasing to the eye nonetheless. This is another homerun for JCA in the aesthetics department. Note that LED was omitted from the LBX due to performance and power concerns.


The Smash community could not have asked for a better mini box controller that has the preferred layout of buttons. Switches and keycaps can be replaced if needed, and soldering should not be a deal breaker.
