ARCADEFORGE / SELECTION GUIDE
Which interface fits your setup?
Start with your video source and the device you want to play on. Compare the connection paths below and see when Pi2Jamma Premium fits your cabinet.
01 / IN AN ARCADE CABINET
Raspberry Pi to a JAMMA cabinet
Pi2Jamma v2 Pro or Premium connects video, controls and amplified audio to a suitable cabinet. Both provide native 15 kHz RGB output and direct GPIO controls.
You need a suitable 15 kHz RGB monitor, matching JAMMA wiring and an image for your Pi model. Premium adds RGB level adjustment and extra connections.
02 / ON A CRT TELEVISION
Raspberry Pi to RGB SCART
Pi2SCART sits directly on the GPIO header and outputs native 15 kHz RGB through SCART. Stereo sound reaches the board through the separate audio cable.
Your television must support RGB over SCART. You also need software configured for Pi2SCART and your Pi model. Plan your controllers separately.
03 / AN EXISTING RGBHV SOURCE
15 kHz RGBHV to RGB SCART
UMSA combines sync from a suitable RGBHV source and outputs RGBS through SCART. Your source must already be configured for 15 kHz.
Plan a regulated 5 V supply and the appropriate video and audio cables. Audio enters separately through RCA inputs. UMSA cannot convert standard 31 kHz VGA output to 15 kHz.
04 / PROCESSING RGB SCART
RGB SCART to a scaler or monitor
Sync Strike processes sync using an LM1881. RGB and sync are available for suitable downstream equipment; stereo audio can be taken from the RCA outputs.
Your monitor or scaler must accept the actual 15 kHz signals and their levels. Sync Strike preserves the horizontal scan frequency. Power comes from an external regulated 5 V supply or a suitable SCART source.
Compare the five interfaces
On a phone, swipe the table sideways. The connection paths above also explain the choice without using the table.
| Interface | Video source → Destination | Controls & audio | Check before buying |
|---|---|---|---|
| Pi2Jamma v2 Pro | Raspberry Pi GPIO → 15 kHz JAMMA cabinet | GPIO inputs, up to 6 buttons per player; audio amplifier | Pi image, JAMMA pinout, power and additional button wiring |
| Pi2Jamma v2 Premium | Raspberry Pi GPIO → 15 kHz JAMMA cabinet | As Pro, plus CPS2 kick harness and switchable CHAMMA pinout | Need RGB adjustment or extra connections? Match your cabinet wiring |
| Pi2SCART | Raspberry Pi GPIO → 15 kHz RGB SCART TV | Separate controllers; stereo audio through audio cable and SCART | Pi2SCART software, RGB capable SCART input and RGB SCART cable |
| UMSA | Existing 15 kHz RGBHV → RGB SCART TV | Separate controls; RCA audio inputs → SCART | Source already outputs 15 kHz; regulated 5 V supply |
| Sync Strike | RGB SCART → suitable 15 kHz scaler / monitor | Separate controls; stereo RCA outputs | Signal/sync levels, 15 kHz support and power supply |
Before you choose
Which Raspberry Pi models are described here?
Pi2Jamma and Pi2SCART are described here for Raspberry Pi 3B, 3B+ and 4, each with suitable software. A standard image is not automatically sufficient. Compatibility with other models is not promised here.
Can UMSA and Sync Strike replace each other?
The signal directions differ: UMSA takes 15 kHz RGBHV to RGB SCART. Sync Strike receives RGB SCART and processes sync for suitable downstream equipment.
Are all the cables and devices included?
Check the scope of delivery and selected options on the product page. Depending on the product and configuration, plan your Raspberry Pi, software, power supplies, controllers, television and signal cables separately.
