Thanks for this suggestion and kind words about the site.

We are working to add more Japanese consoles because their value is very different and there are lots of exclusives.  I'll wait to see how this issue is received by the community to decide how to prioritize it with other suggestions.

We don't track hardware from other countries at this time.  Just NTSC released hardware.

Not enough info.

I'll see how popular this request is before adding these.  We don't generally track 3rd party hardware, but these are pretty valuable so if users want this added we will do it.

We have the Pokemon Center GBA here:

Green 3DS is here:

Was the "Wonderful World" DS released in the USA?  I don't see any sales from the US, just Europe and I don't see any hard evidence that it came out in USA.

Added it now.

A good list of Fairchild F games:

Fixed.
