Some Questions about 3.Gen(RSE/RSS;FRLG/FRBG) region/language editing

[BlueMew92]

Hallo Guys, I´m new here because off some problems I have with save-editing on 3.Gen (at the moment)

So, my first Question is:

,,How can I edit the region/language of a save-file?" I want to make a (J)Japanese Emerald.sav an (E)EU/German/... Smaragd.sav

Is there a tool I missed on my search through the WorldWideWeb? Or do I have to Hex-editing it on my own? I need a little "CrashCourse" in Hex-Editing or even a Tutorial because I can´t finde a side where to learn it.

Next Question:

Does PSavFixV2 edit all 3.Gen checksums correctly or only R/S (E?/J?/UK?)

I hope for an answer
