Good
Deal Games constantly receives inquiries about how to program
for the classic systems. In response to reader demands,
we contacted ace Colecovision programmer Daniel Bienvenu
and he was kind enough to share his entire documentation
and toolkits. This is simply HUGE as these docs and tools
would require years to develop. Thanks again Daniel!
We cannot express how thankful that we are to Daniel for
his very generous donation. The contents of all the materials
are simply too extensive to cover on this page, but you
can download the documents in their entirety below.
