Re: Smaller font on the NXT
I have two font packages that I use (I didn't make them, but I did modify them). One is 3x4 active area, and the other is 4x5 active area. I don't know if ROBOTC supports .ric fonts, but it's fairly easy to use them in NXC.
See this page
for several examples, as well as several font packages. See this page
for a tutorial for building your own, as well as an explanation of how it works (to a very small extent).
With 3x4 font, and 1 pixel white space between characters, you can have 25 characters per line, and 13 lines (which equals 325 chars). Default font is 16 chars per line, and 8 lines = 104.
