These are the most common known problems with VICE 0.12.0:

- audio support on Solaris and HP-UX is buggy; in particular, the automatic
  refresh rate setting is known not to behave as it should when sound is
  enabled, and sound does not stand slowdowns as it should (and as it does on 
  other systems);

- 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);

- invalid Directories on D64/X64 disk-images can make the emulator and the
  c1541 utility die with a Segmentation Fault, instead of reporting an error
  (this is not a problem when hardware-level 1541 emulation is enabled);

- setting the CIA latch registers to low values can make the speed drop down a
  lot (if you find a game that runs _much_ slower than usual, you have probably
  caught this bug);

- reading the keyboard ports from the CIAs is slow;

- setting a maximum speed limit does not always work because of limited timer
  resolution on many systems (e.g. on Linux, the maximum resolution is 10msec,
  so setting speed limits above 200% always gives 200%);

- 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;

- the hardware-level 1541 emulation handles GCR only upon reading, not writing;
  write support is achieved by patching the drive ROM, and this can cause
  trouble; moreover, there is no support for formatting tracks (yet);

- Heart Of Africa for the C64 does not like our write traps (it could work in 
  read-only mode, but it is not implemented yet);
  
- 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;

- xvic and xpet do not support tape images;

- the C64 and VIC20 cartridge ROMs are not emulated;

- the VIC20 has no joystick;

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

- the MS-DOS version is not fully functional yet.
