====== MEGA65 Wiki ======


Here's an initial attempt to wiki-fy existing knowledge on the Mega65 system garnered from the user forums and Paul Gardner-Stephen's blog.

It's intended as a draft effort, to demonstrate how this information would look when presented in this form.

For now, I'll just add pages into a linear list below. Later on, as content grows, I'll try provide more hierarchical/tree structuring.

===== Introduction =====

  * [[https://c65gs.blogspot.com.au/2014/01/motivations-and-goals-for-project.html|Motivations and Goals for the Project]]

===== Walkthroughs =====

  * [[MEGA65 Prerelease Starter's Manual]]
    * Steps for how to get your Nexys board up and running with the MEGA65 bitstream
  * [[Preparing a build environment in Cygwin]]
    * For windows users that don't want to jump ship completely to Linux
  * [[FPGA Development Walkthrough]]
    * Guides you through the installation of the Xilinx ISE WebPack software and its usage
  * [[https://github.com/MEGA65/mega65-core/blob/master/doc/index.md|MEGA65 GitHub docs]]
    * Search these github docs via the 2nd search-bar above
    * A few github *.md doc files presently accumulating in the official github repo.
    * They cover some common ground as the existing wiki walkthroughs, with more dev-related details
    * They also have a more linux-centric approach, if that's your preferred path (over windows-cygwin)

===== Documentation =====

  * [[https://docs.google.com/document/d/1fmEUg6hDdWRb2tFZ3n4LG7S1mNP04_SUAW5DrE8zRpk/edit#|C65GS System Notes]]
