I did a bit of checking for Pixeljunky. In addition to what he requested, there's a fair amount more.
Dracula X ￥12,000 (complete and mint)
Dragon Knight and Graffiti ￥5700 (one in good condition, one slightly less so but including postcard.)
Hi Leg Fantasy ￥8400 (includes GE card)
(Pixeljunky has first dibs on these)
Also:
Popful Mail ￥5000
Bazaru Degozaru ￥12,000
Downtown Nekketsu Monogatari 13,000
Also, they had a front loading Neo Geo CD boxed for 18,000. Those are rare, IIRC.
Oh, and Darius Alpha for 84,000, but I don't think I want to trade for that much. 
I bought these from an online Japanese store two months ago:
Popful Mail ￥4,190
Downtown Nekketsu Monogatari ￥5,590
I thought that was a little funny, so I went back and double checked. The Downtown Nekketsu Monogatari was sealed. The Popful Mail is complete and in very good condition.
Are you in Tokyo ? I'd like to get PC Genjin 3 Special and if you can get it this week-end, I can give you an address in Japan where you can ship it.
Sadly, there are already two other people who are interested in getting the Bonk 3 taikenban. If they both drop out, I'll let you know.
would you ship to new zealand at all? and do you think the store would shift on any prices at all? 
I suppose I could do that. What are you interested in?
The prices won't shift. Those special versions have been sitting there for a couple of years with no changes.
