Due to the nature of Gen 1 to 7 Mew transfer, there really isn't much that would be changed. I recall ID also being needed, not just OT. GF didn't even prohibit that mew being shiny, in fact the only shiny mew that can exist is a Japanese gen 3 mew, but the GTS has been full of hacked shiny mew...
We all be glad if you can upload them. On a personal note, I prefer the savegame being uploaded rather than the pk1 file. If you don't mind uploading it, I would appreciate it. In any case any contribution is awesome!
