Work started on the BUS driver for Harmony/Melody last weekend. Provided that pans out Draconian will be rebooted to use it.
Sadly, it hasn't panned out. While the results are very impressive, BUS doesn't consistently work on some Juniors (or some 7800s). So cd-w and I have created CDF, a new bankswitch scheme that takes ideas from DPC+ and things we learned creating the BUS. CDF doesn't have as many features as DPC+, but is significantly more flexible (rather like the 2600 in that regard!) and better suited to projects that utilize the ARM in the Harmony/Melody.
We progressed far enough with it that I've already begun the Draconian reboot
as part of testing it. It's non-playable at this time, so builds are only available in my blog. Two
have been posted since the reboot, in those I've rewritten the menu and score routines to use CDF.
At this time those builds only work on a Harmony Cart. I'm adding support to Stella, but it's not yet in a publicly available build. However, I foresee it becoming available in one of the 5.0 pre builds in the near future so keep an eye on this topic
. On that note, if you haven't already, I highly recommend
you download the latest test build of Stella from there so as to provide feedback on the new TIA core - the more eyes looking for bugs the better!
