&lt;br /&gt;
* [[Nicola Salmoria]] and [[Charles MacDonald]] FD1089 decryption:&lt;br /&gt;
** 100% accurate emulation of FD1089A, FD1089B should be considered 99% because it will have to be verified with other CPUs (it is 100% for all currently supported games).&lt;br /&gt;
** complete tables provided by Charles MacDonald for 317-0018 (Action Fighter), 317-0022 (Dunk Shot), 317-0168 (Aurail).&lt;br /&gt;
** partial tables derived by comparison with the unencrypted versions for Enduro Racer, Alex Kidd, 317-0024 (Time Scanner), 317-0033 (Alien Syndrome, 3 versions), 317-0027 (SDI). (actual working cpus are needed to obtain full tables)&lt;br /&gt;
&lt;br /&gt;
* [[Aaron Giles]] completed a big Sega Update:&lt;br /&gt;
** dunkshot graphics correct, controls hooked up&lt;br /&gt;
** sdioj controls hooked up&lt;br /&gt;

Note that in the process, he broke the title screen animation for Laser Ghost, and there is now a 1-pixel column error on ddcrew&amp;#039;s attract mode. These are known issues that I will try to address soon.&lt;br /&gt;
