Frequently asked questions
A few quick answers from our technical pages. Always check your particular hardware before connecting anything.
Do all DB15 supergun controller ports have the same pinout?
No. Button assignments and some conventions vary by supergun model and revision. Verify the exact pinout first.
Are JAMMA and JVS interchangeable?
No. JAMMA uses a PCB edge connection carrying several signal types, while JVS uses system-specific I/O boards and communications.
Can I buy USB2JAMMA today?
Not yet. Design and validation are still in progress. We are not making commercial compatibility claims.
