Yep Shenmue 1 had the exact same issue the 39 8E E3 3F swap to 8E E3 18 40 or 39 8E 63 40 fixed it perfectly there. The cutscenes were 21:9 and the UI was 21:9 alsoBy the way, reading back on this topic I got the impression that you had this working fine on 21:9.
Was it just for Shenmue I?
Shenmue 2 has the same 39 8E E3 3F value but when I change the values to either of the above the UI is still messed up.

combined with the new Shenmue I & II 16:9 Generic Hex Fix have at least made the controls visable now it still repeats but at least I can see what buttons to press. this makes it playable. Thanks
