gbalzss by Andre Perrot
get it here:
http://gbadev.org/tools.php?showinfo=56quite a nice little command line program.
the first time, i decompressed the spanish one instead of the english one. it definitely left me pretty confused until i realized that there was more than one directory containing the same files, but in different languages.

6C306C30 comes at the end of each text box worth of text, it looks like.
quite a few files are uncompressed, which is nice.
also, based on what i've read, all of that cast_event_msd isn't compressed, either. i guess someone was taking the actual compressed files out of it with a hex editor, and decompressing them with gbalzss. the procedure seems fairly un-complicated.
at any point, can you select kana as a menu option anywhere? cause it's mentioned a few times in the "babil_menu.msd" file.
this is pretty cool to look through.
when you use focus a few times, is there ever a way to tell how many times you have, outside of just paying attanetion and counting? cause i don't remember seeing this(from babil_battle):
R.o.u.n.d.s. .o.f. .f.o.c.u.s.:. .%.c.h.r.8.4.%
also, at the end: D.u.m.m.y.5.....D.u.m.m.y.6
in babil_item, i found O.m.e.g.a. .T.a.i.l.....Z.e.m.u.s. .T.a.i.l, which is neat to see for myself, even though everyone knows about it already. there's also "dummy 1" through "dummy 40" in there. those tails are actually mentioned more than once. there's the item name then the "the tail of ****" description.
