These are the most common known problems with VICE 0.13.0:

- the `automatic' refresh rate setting does not work too well under Unix:
  it usually gives a refresh rate that is lower than the one you would get
  with a fixed value at 100% speed;

- audio support on Solaris and HP-UX is buggy; in particular, the behavior of
  the automatic refresh rate setting is wrong when sound is enabled, and the
  driver does not stand slowdowns as it should;  [in 0.13.0, it is likely not
  to work at all]

- the TextField widget can cause an X protocol error on XChangeProperty():
  to fix this, recompile with the `--disable-textfield' option and (please)
  tell us (we only experienced this once, on a DEC/Alpha machine, and did
  not have the time to find out why);

- changing SID registers often is slow (e.g. when playing samples using the
  volume register);

- setting a maximum speed limit does not always work because of limited timer
  resolution on many systems;

- P00 file name handling is not exact, as you must use the file system name 
  (with the P00 extension) instead of the one specified in the P00 format;

- GCR writes to disk images in full 1541 emulation mode are not 100% emulated
  (the provided emulation should be enough for most pourposes, though);

- there is no support for wildcards on the FS drive access, but they can be
  used when reading the directory (eg. LOAD"$:gamez/*.p00",8);

- the VIC-I chip in xvic still lacks important features and is still under
  construction;

- the CRTC chip in xpet only supports the basic features and is still under
  construction;

- the VIAs in the PET, VIC20 and 1541 emulators are _not_ cycle-exact;

- xvic and xpet do not support tape images;

- the C64 and VIC20 cartridge ROMs are not emulated;

- the VIC20 has no joystick;

- changing the REU image name via resource files has no effect until exiting;

- dithering on monochrome X11 servers is *very* slow;

- adaptive sound speed is not supported on MS-DOS.
