I was just going to point this wikia page
RBF fonts - CHDK Wiki out to you,
when I realized there was nothing usable there... anyway there is now: a link to all menu and symbol fonts that
I could round up in my archive.
How to: put the .rbf files from the 'fonts' directory in the /CHDK/FONTS on your card, and likewise
.rbf from 'symbols' into /CHDK/SYMBOLS on your card.
Then (in CHDK) goto to menu 'Visual Settings' and choose select 'Menu RBF Font...' select your font - they come
in all sizes. Likewise for menu symbols (just make sure font size > symbol size, or it won't show)
hope that helps,
wim
