Introduction
The JVS-PAC is a small device that enables you to play MAME on your JVS cabinet with a minimum of hassle.
First off, there are a couple of important points that has to be made, and duly noted:
- JVS-PAC is not a business - this is purely hobby project, they are literarily made on my coffee table..
- JVS-PAC is not an ultimarc.com product - and I am not affiliated in any way with ultimarc.com. (I am however a happy customer, and Andy didn't mind me using the name JVS-PAC)
Short introduction to JVS
JVS, or Jamma Video Standard (sometimes even called JAMMA 2), is a specification by a JAMMA special sub-committee consisting of the major arcade game manufacturers.
JVS specifies the type of connectors to use for video (HD-15), audio (RCA) and power (JST VL), in addition to the communications protocol between the game board and the I/O board. In contrast to (old) JAMMA, JVS concentrates I/O functions in a separate board. The protocol is well documented, but only in Japanese (thank you google translate & altavista babelfish :) )
Short introduction to JVS-PAC
The JVS-PAC behaves like a JVS game to the I/O controller, and a USB keyboard to the computer it is connected. The keyboard output is mapped to standard M.A.M.E keys.
The main advantages of this setup is:
- No special (or modification to existing) cabling required - all buttons work out of the box
- You can swap between MAME and JVS games very quickly
- Your JVS cabinet stays original
- It's easy
