I've translated "Sinnoh Region's Mythology" on this page: http://bulbapedia.bulbagarden.net/wiki/Sinnoh_myths
Sorry it's not an actually a link, I'm using my iPod. Anyway, here's the translation:
Lingrah vod, fod Sinnoh lost yun
Sunvaarseluh ahrk joor lahney
voaavaht lasse.
Votinvaaktaas nust vodreh voahraan
enook vorey. Nust drey.
Nust ofan rahzasse,
ahrk skiilan enook vorey.
Sunvaarseluh luaan voreyye
wah kos nuk wah voahraan joor.
Nii luaan Sunvaarseluh kos nuk wah
genun wah joor unstiid.
Ful wah daar sul, Sunvaarseluh genun
fod mu bo kotin lingrah veydo.
How did I do?
