I've been studying the VIC-II datasheet and how the C64 initializes it when
booting.

The only thing I've seen while booting is

LDX $#FF
[...]
STX $D016

that I think is a kind of "enable 40 columns text mode". Then, I think that
things like the base memory address and foreground and back colours are also
needed to be set, and that's it, isn't it? Because once set, the VIC-II just
reads memory and renders the data it finds there, leaving up to the KERNAL,
BASIC or whatever is running in the machine to generate that data.

What do you think?
