As someone who owns the Japanese version... the OP is selling the Chinese version. This is an actual PCB that can be used in JAMMA or JVS. Either in 15khz or 31khz. But in 15khz, it will run in interlace. In 31khz, it will run progressive.
For all interested, this is official hardware. It's called the System Board Y2. It has options for both JVS and JAMMA. For KoF 2002, this is essentially what KoF '98 Unlimited Match was on the PGM2. There's hi-res backgrounds, character portraits, and a pretty cool animated intro. The soundtrack is also arranged and is excellent! The version I have allows for Chinese or English language selection. It also has a button config in the soft settings which I always find handy. If you like KoF, it's pretty great all around.
