I modded the TSRO sro_client into an english client.
Much faster than pk2 editing in my opinion.
Works. Virus free.
Directions: All you have to do is update silkroad online to the latest, which currently is 1.201 I believe. Replace the current sro_client with my modded sro_client. Enter game and things will be in english.
