Wow, sorry, I patched the .xbe from the spanish translated version,
I'll try to fix that and upload an english version.
There is nothing I can do about geometry disappearing outside the 4:3 area, sorry. except maybe, crop the fov area, but this would result in a very tiny field of view.
About the game running 720p it should be possible, I tried to hex edit the game to do so, ( there is also a fantastic tool for that made by MarvelousMirth) that allows to jump the internal resolution higher than the developers intended to but the end result is the same, the game hangs at the first loading screen, we are missing something.
Some Sega games for the xbox are actually patchable to run at 720p on XBox,
Gun Valkirye. (playable)
Jet set Radio Future. (heavy slowdowns)
But as said Shenmue II refuses to start after patching the resolution, at least on my console.
Sorry again.
