Someone did a semi-translation of Shenmue II for Dreamcast, as there was only ever English text with Japanese dialogue on that version. As the later XBOX version had dialgoue, this eventually appeared
Shenmue 2 Full English Xbox Speech mod for Sega Dreamcast.
I've never tried it, partly because the audio is so downsampled it's supposed to sound appalling, partly because I really can't stand the English dubbing of Shenmue unless it's for a brief laugh.
On the matter of translations and language, in the past I've been in many situations where I've gotten by but wished I could read just a little Japanese. On the Gamecube I've got the Japanese versions of Resident Evil (which had English dialogue but Japanese text) and Phantasy Star Online 1+2 Plus (which you can select English for...when you eventually find the options menu!).
At the other end of the scale are things like Final Fantasy for WSC or any of the Metal Gear games, all a nightmare with no English.
