I've just recently started trying to learn 6502 machine language, and it can be a
tough language to program in, and is
especially difficult to debug. I can
imagine that it takes a lot of time and
talent to code a quality game in machine
language, particularly considering the
tight memory constraints of the 2600. To
echo what's already been said, I guess I
feel that it's important to support the
people who put the time and effort into
programming these homebrews. They're
producing great games and helping keep the hobby alive.
