+GRU Devlog 32 - yemu
+</title><description><![CDATA[
+
+<p>This 2 weeks I was coding yemu. I added handling for flags, so now after any operation ZF and
+NF flags changed to correct values. Also I added opcodes for CF manipulations, so carry flag
+can be set and unset. Also I was fixing and detalizing specs, because I needed it to implement
+other commands. I added logical instructions - AND, OR, NOT, XOR.</p>
+
+<p>This week I was mostly researching about something that can be interesting, but don&rsquo;t have
+enough information for a project yet. It is pretty complicated sphere, so I don&rsquo;t know when
+I will do something interesting there.</p>

-<p>Happy Chirstmas! Next GRU Devlog will be next year so Happy New Year! I hope GRU will grow
-and grow next year :D</p>
-
-<p>On last Sunday we have created mailing list after devlog. Currently it is not active, but
-but you can message us there - gru@lists.tildeverse.org. Then I tryed to make FILE struct
-for liblinux, but it wasn&rsquo;t working so it needed to be reimplemented.</p>
-
-<p>Then youngchief submitted some changes to our webpage. Also robyndrake contributed some fixes
-to coreutils.</p>
-
-<p>Also I had implemented printf and vprintf! It currently have %c, %d, %s so it will be useful
-for debugging. I have tryed to implement snprintf, but i had several problems with it so
-it is not done yet.</p>
-
-<p>Then chunk contributed logo for us! I think it looks nice!</p>
-
-<p>Last useful thing that I have done this week is very minimal FILE, it currently just has
-fd and nothing else.</p>
-
-<p>I hope we will make more cool things and finish current projects next year!</p>
-
-<p>Hope you liked this post! I wish everyone cool New Year!
