EDIT 1: I can now confirm that this happens with all Gen 3 games, not just Emerald.
EDIT 2: Seems as if any Trainer Info modification has this effect. I had a FireRed save file with the Trainer Name "MATT", and simply changed the Play Time from 0:00:12 to 0:00:01; this then made PKHeX view the save file as Japanese rather than English.
Tested with latest commit and all Gen 3 games (most testing done with Emerald). To replicate:
Load any English Gen 3 save file
Open Trainer Info Editor
Change Trainer Name to something with 4 or less characters
Save changes and export SAV
When loading the save file up a second time in PKHeX, it now automatically detects the save file as Japanese, rather than being English.
In my first set of testing, the Trainer Names were:
"MATT!" (unmodified); was recognized as an English save file
"MATT!!" (modified); was recognized as an English save file
"MATT" (modified); was recognized as a Japanese save file
In my second set of testing, the Trainer Names were:
"MATT" (unmodified); was recognized as an English save file
"MAT" (modified); was recognized as a Japanese save file
