I found it runs with less problems with no$zoomer 2.3.0.1 (does not have EX options at all) than 2.3.0.2.
Well actually I skipped back to 2.3.0.1 not long after the intro which seems to have some corruption on 2.3.0.2 regardless of EX options, and yeah, EX4 puts back the clock in 2.3.0.2 (it's visible in 2.3.0.1).
Without no$zoomer, only the clean emulator, all of the issues are present.
Anyway...I can't find any way to fix the missing text and corrupted char images either.
Also the words "Victory" and "Defeat" for battle conditions are not visible either ..well we can say not visible since 1 visible letter doesn't count and there are more of these little corruptions but it's OK in general

...it's not a big problem like the main text in the story.
