+In this directory, you will find the source file for the main font used by
+CATSFC. It's an Adobe BDF file, which is fed into the emulator when running
+in "font dump" mode to produce a more efficient representation in an "ODF"
+format. The font is based on the one used by Pictochat, with a few more
+characters that Pictochat does not have (but no Japanese characters).
+
+You can edit the font in an application that reads BDF bitmap fonts, such as
+FontForge. Open the font in the application then export it again as BDF.
+One case where you would want to do this is to add new glyphs to support a
+new language.
+
+To include the more efficient representation (ODF) in CATSFC/system after
+editing the BDF file:
+
+ 1. If your font added characters beyond U+2193 DOWNWARDS ARROW, adjust the
+    maximum codepoint in source/nds/bdf_font.c, after the first instance of
+  > #ifndef HAVE_ODF
+ 2. In source/nds/bdf_font.c,
+  > #define DUMP_ODF
+    and
+  > // #define HAVE_ODF
+    This will make the plugin read the BDF source and write an ODF file.
+ 3. make
+ 4. Copy the new plugin to your card, under /_dstwoplug.
+ 5. Copy the .bdf file to your card, under /CATSFC/system, as Pictochat-16.bdf.
+ 6. Run the plugin on the Supercard DSTWO. It will briefly load, then display
+    "Font library initialisation error -1, press any key to exit". This is
+    because it tries to load the Chinese font's source, Song.bdf, which you
+    don't have. Regardless, it does dump an ODF file for Pictochat-16.bdf.
+ 7. Copy the .odf font somewhere on your hard drive if you want to keep a copy
+    of it. Delete the .bdf file from your card.
+ 8. Reverse the changes made in step 2.
+ 9. make
+10. Copy the new plugin to your card, under /_dstwoplug.
+
+And you can use your new font!
+
+Finally, you may want to send your .bdf source file to a CATSFC developer
+or commit it to a fork on Github, for inclusion in the plugin. You may also
+want to send your changes to CATSFC/system/language.msg for the same reason.
