The Biohazard games will have to wait until we add more Japanese releases for other consoles.

We are gathering price data for Famicom and Super Famicom now.  Please take a look at these game lists:

www.pricecharting.com/console/super-famicom

Let me know if there are any mistakes or missing games or other issues.  These are not linked from anywhere on the site or included in search results yet.  We are waiting for more price data to come in before full launch.

Please let me know when you are done.  I'd love to see it.  I'm also looking for some external sites that are doing it that I can share as examples for inspiration.  I'd love to share yours and link to your site.

Great feedback.  Many of the changes you suggested are now live.  Including the "powered by" image, all links open in a new tab, and all users (even the seller) will see the same results which makes testing easier.

This is live as of yesterday afternoon.  If you add a new item with box and manual (and we have a value for those items individually) we will calculate the value.

This change will propagate through the existing items in a collection too as we update collection values.

Thank you for your input on the wish list feature.  I'll look into this more and decide how best to implement it.

Great feedback.  That result is intentional.  Ideally I would like to change that behavior to make previewing a bit easier, but it is a fairly difficult thing to change in the backend.  Because the private browsing solution works I decided not to implement the fix until I get some more feedback from users.

Thanks for letting me know you would like that addressed in the future.

I've added both of those now.  They will show up on the site within 4-5 hours and prices will follow as soon as we see some sales data on them.

Yes, please let us know the titles missing and we will add them.
