I'm after a complete (& in good condition) Gem Smashers for the GBA, published by Metro 3D (M3), developed by Frame Studios & released in the US in 2003. There are a few copies on Amazon.com going for roughly $20.00, although the sellers won't ship to the UK. And I haven't seen any copies on eBay at all.
If anyone can help me out, I'd be very grateful. I am in the UK, so postage will be around the $10-$12 range. Thanks.
