Recalbox RGB JAMMA 2 brings Raspberry Pi 5 to arcade cabinets

Recalbox’s RGB JAMMA 2 is less about novelty and more about making a Raspberry Pi feel like real cabinet hardware. The practical win is the workflow: instead of fighting a loose DIY stack of boards, adapters, wiring and heat, the new setup is built around the Raspberry Pi 5 and packaged for JAMMA cabinets with a matching adapter, a white resin-printed case, an information display and a 40x40x20mm fan.

That matters because arcade cabinets are cramped, warm and awkward to service, and Recalbox is clearly trying to reduce the usual friction points. The company described RGB JAMMA 2 as a “logical evolution” of the first model, not a fresh reinvention, and the difference shows up in the details. The official shop lists the RGB JAMMA 2 Complete Kit, Pi 5 only, at €130, while the Raspberry Pi 5 and SD card are sold separately. The kit is aimed at people who already own a JAMMA cabinet or are ready to build a more complete setup around one.

The hardware story is only half of it. Recalbox says the new board adds interlaced display support at 480i, native GunCon support and coin counter support, all of which push it closer to the kind of cabinet-first setup operators used to have to cobble together manually. The product page goes further, listing 15kHz and 31kHz output, 0.5 ms input lag, 3- and 6-button support, CHAMMA kick-harness support for CPS1 and CPS2, a 15-watt mono amplifier, stereo jack output, TATE mode, support for mechanical and electronic coin changers, Game Center mode and 4-player mode on the CPS2 kick harness.

Recalbox’s own wiki makes the target audience plain: JAMMA standardized arcade wiring in the 1980s and is still common in older CRT cabinets, and this product is not for people who do not own or plan to buy a JAMMA machine. That is the right kind of bluntness. RGB JAMMA 2 is not trying to be a universal retro box; it is trying to be a cleaner, more disciplined cabinet brain for people who want the setup to behave like an arcade board, not a science project.

The Raspberry Pi 5 gives that idea real headroom. Raspberry Pi announced it on September 28, 2023, with pricing starting at $60 for the 4GB model and $80 for the 8GB model, and said it delivered more than twice the speed of the Raspberry Pi 4. That extra room is exactly why this kind of JAMMA build makes sense now: enough power for demanding arcade and console content, without the mess that used to come with making a Pi behave inside a cabinet.
