Small thing: The th095e.exe file doesn't have the icon with the "E" on it (like the installer does) like most of the other english exes. Not that important though.
Also, what was the actual reason behind needing a different score.dat for the english version? In every one of the other patches, I'm pretty sure they both share the same one. What's different about StB? It would be nice to be able to play both language versions and not need to clear everything twice (or just do everything in the JP version, then convert it using the patch, which kind of defeats the point)
Finally, did you say you removed the text on the best shot? On the english version, my best shots are garbled text at the moment, but they are copied data from the other. Maybe it would just be better to not display it in the english one like you were doing, to allow both exes to use the same data as well.
Thanks for all the work though, it's nice replaying things in my natural language.
