<h2 align="center">Known Bugs</h2>

VCC definitely has a few bugs, but some are a little more "evasive"
than others.

0. Composite & RGB colors are *not* exactly correct. This is being
worked on.

0. The CPU is not exactly "cycle accurate". It's just a hair slightly
faster than a real CoCo 3 and there are a couple of things that this
causes problems in. For example "Popstar Pilot" has a screen flicker
and a couple of SockMaster's demos will not work correctly. These
programs count cycles in the render process and VCC is slightly off
in timing. As soon as we find the timing issue, this will be fixed.

0. When using VCC & DriveWire4, sometimes when doing a cold start (F9
twice), VCC & DW4 will lose sync, and VCC will have to be restarted.
This is mostly DW4 related and we don't think VCC is the culprit.

0. There's a problem in the disk drive emulation in which IRQs are not
being handled correctly. It doesn't bother "normal" use, but if you
play around with the drive commands directly via ML, it will show
it's nasty head.

If you know of any other bugs, please report them to the "Issues" page
on the VCC GitHub site where you downloaded this installation package.
