The 2nd VCF Montreal dates have been announced, and they have moved a few
months ahead to avoid the dead of winter (it was in January earlier this
year; the next one is November 7-8 this year as well). It’s at a new
location closer to Montreal proper (Champlain College Saint-Lambert):

Game On news (all Coco related platforms):
==========================================

None of the usual game play videos or speed runs came up. You'd think it's
the last week of summer holiday or something. A few MC10 games... so we
didn't split them out this week. Let's pretend it never happened.

Coco 1/2/3 (and multi-platform)
-------------------------------
1) Chris Burke has been teasing with several posts on Facebook about getting Doom to run on a Coco 3 (maybe accelerated via emulator, maybe not). He has been working on the palette settings and using dithering patterns to match as close as we can. (I will mention that this video is running on a modern Linux machine, but it is using the palettes & dithering that would be doable on a Coco 3):
https://www.facebook.com/groups/2359462640/posts/10164685231147641/
Some more dithering options:

7) Glen Hewlett posted on his blog that he now has his Disk Extended BASIC stand alone assembly library ready. This lets you call disk routines *without* requiring Disk BASIC at all (and thus using memory for all of it’s functions when you don’t need them):
