Turbo --> Duo connector and other random Duo questions

Hello all,
I finally got a Turbo Duo about a week ago and I need to come up with a
solution for its dreadfully short controller cord length.  Since I already
had a TG-16 with two controllers and a Turbo Tap, I was planning on buying
the adapter cable from TZD that allows you to use Turbo accessories on the
Duo. My first question is that I realize this will work fine with the Turbo
controllers, but will this cable also work with a Turbo Tap (with several
Turbo controllers) plugged into the Duo? Also, does anyone know what the
length of this cable is? I'm thinking I will have to buy controller
extensions on top of this if it is really short.

Secondly, along with the Turbo Duo I received the U.S. Hu of Samurai Ghost
with manual. The game appears to be a sequel to a Japanese Hu I have (which
I also have on a Namco Museum disc where it is called The Genji and Heike
Clans). Is this one of the games that TTI put out without a box like Magical
Chase? How many games did TTI release with only a booklet and game?  I'm
assuming its a pretty rare late release considering GameFAQs doesn't even
have a listing for it.

My next question I have asked before but wanted to pose again if anyone had
any further information to add.  I have the "green diving board" convertor
for Japanese HuCard games and would like to use this on my Duo. It works
perfectly on my regular TG-16, but not the Duo. It also fits perfectly in
the Duo but will not load the games (did the same thing on my friend's Duo).
Does anyone know a simple mod I can do to it to make it function correctly?

And finally, I have a few extra games up for sale/trade now if anyone is
interested.  Currently I am seeking a copy of Parasol Stars (must have case
and book but not necessarily outer box) and I will trade more than one of
these games to get it.  I will also accept other trade offers you may have,
please e-mail if interested.
Here is the list:
1.Last Alert (CD)- case, cd, manual all in excellent shape
2.Ninja Spirit (Hu) - Hu, generic cd case with photocopied manual
3. Blazing Lazers (Hu only)
4. Sidearms (Hu only)
5. Two copies of Keith Courage! (Hu only) ;)

Thanks!
