Honestly just leave Solo 2000 in there unless you can interchange it with a 2P Mix board that has all the hacking done for you.

there are versions of the doubles mixes that have been modified to ignore the I/O checks so they will boot in a solo machine

they don't work very well though since you end up with 1 sensor per arrow
