ok, checking the first version of the spanish translation I did in the past for SI+SS, and not testing the DOS versión throughfully, I'm doing it right now.
I added some of the fonts for spanish language, accents, 'ñ'... and another little things, and I played flawlessly with Exult the translation.
Comparing a bit more DOS/Exult versions, and using the same FONTS.VGA and USECODE texts, I've found this things:
Scroll text in spanish
Dialog text in spanish
In fact, this is not a running problem, it works well, but as you can see, somehow the fonts are not printed in-game equally. You can see that in DOS texts there is lower spacing between lines, and Exult seems to treat different this thing.
I've edited the Fonts to have his offsets (coordinates x,y) to align with the rest of characters.
Is supposed that this is how work in Exult?
