You're definitely going to want the non-fast I/O version, unless you happen to have a Taito Fast I/O installed in your Vewlix. The @Niko multi works fine with just about any common JVS I/O, so the JVS ttx2 will give you a broader range of options.Hi, I'm not sure to be honest. I got a newly acquired chewlix that I'm wanting to set it up with NESiCAxLive. Do you know if just need the i/o controller board?
