Sounds like someone is trying to save thier sphere world, to transfer it to a RunUO shard
You would need an Export function in your Sphere shard, frst off... Then you can use the Export items, and export the world, 0, 0, - whatever your map is at the SE corner.
If you have the Import/Export that my friend Allmight has submitted to the Forums, you can then use it to Import them to RunUO.
I know nothing of Sphere though, so I am unsure how any export script works for it, and if it writes to a *.wsc file the same format that the DHR Import/Export for RunUO reads/writes.
But if it is compatible to UOX *.wsc files, then it will work fine.
