I'm interested in buying any confirmed working Beatmania arcade upgrade/conversion kits (i.e. the 10 removable chips and the hard drive). As I'm mainly trying to test out my 5-key machine, I'm mostly interested in low-cost kits. Early mixes are fine, though I'm open to anything as long as you can confirm that it's working.
Obviously, chips/HDD are musts - marquee is optional, though always nice. The only one that I'd be willing to take chips only (i.e. without the HDD, since I already have one) is Beatmania Complete Mix 2.
PM me with offers. Thanks!
