Turns out that I was reusing a makefile intended to to test the 2-page modes
which reserved more than twice the amount of memory than necessary. I can 
load 2 fonts at a time now and I'm only ~1K short now.

Yes, I figured it out :) It seems that tgi_load_vectorfont doesn't clear the tgi_error
status even if it succeeds. That apart, unloading litt.tch and scri.tch and loading 
goth.tch before screen9 did the trick. Everything works fine now :)

Btw, me and my brother (who's not into 6502 at all) were using the Borland stuff
back in the days. He immediately recognized the fonts and was motivated enough
to port a mandelbrodt program he wrote for some cell phone to cc65, without knowing 
anything about 6502. It works but it needs a little more work, I'll share it when it's done.

This is one of the finest examples of what I call "technology recycling", stuff like "the
snake game" being the most popular game again during the early 2000s :)


ps: Why so low in 2007? :)
