Release notes for lxdream 0.9.1 "Turtle"
nkeynes@177
     2
===================================================
nkeynes@177

nkeynes@1048

Lxdream 0.9.1 is mostly a performance release (core emulation is a good
nkeynes@1048
     5
33-50% faster, although rendering performance is still bad), with a few new
nkeynes@1048
     6
features like VMU and LIRC support. As for 0.9, the majority of software can
nkeynes@1048
     7
be expected to "just work" with minimal problems.

nkeynes@897
     9
Nevertheless this should still be considered an alpha release, with many 
nkeynes@897
    10
unimplemented features remaining. You're unlikely to see 'perfect' emulation,
nkeynes@897
    11
and we're nowhere near being bug-compatible (in other words, don't expect your
nkeynes@897
    12
code to work on the real hardware just because it runs correctly in lxdream).

Changes since 0.9
nkeynes@1048
    15
-----------------
nkeynes@1048
    16
* Lots of core performance improvements, especially with the MMU turned on
nkeynes@1048
    17
* VMU support (memory card only)
nkeynes@1048
    18
* GDB remote debugging support
nkeynes@1048
    19
* Quick-save states
nkeynes@1048
    20
* LIRC driver
nkeynes@1048
    21
* Now uses the ~/.lxdream directory (by default) to store runtime data
nkeynes@1048
    22
* Audio + input drivers are now built as plugins
nkeynes@1048
    23
* OSX: fullscreen support, minor UI improvements

Known issues
nkeynes@897
    26
------------
nkeynes@897
    27
The following are known problems in 0.9 that will be fixed in the next major
nkeynes@897
    28
release - in other words, you don't need to report them - we already know :)
nkeynes@897
    29
nkeynes@897
    30
* Graphic artifacts related to translucent triangle intersections, sorting errors 
nkeynes@897
    31
  and/of lack of depth precision.
nkeynes@897
    32
nkeynes@1048
    33
* Rendering performance ranges from barely acceptable to abominable.
nkeynes@897
    34
nkeynes@897
    35
* The SH4 emulation is not cycle accurate, and (by default) usually runs
nkeynes@897
    36
  slower than the real one. This cause some programs to have timing problems
nkeynes@897
    37
  or to break completely. In some cases this can be worked around by
nkeynes@897
    38
  adjusting the CPU scaling factor (-m command line option)
nkeynes@897
    39
nkeynes@897
    40
* Audio quality generally ranges from poor to horrible, interrupted by the
nkeynes@897
    41
  occasional bit of fair-to-middling sound.

System requirements
nkeynes@897
    44
-------------------
nkeynes@897
    45
Linux:
nkeynes@897
    46
   GTK 2.6+
nkeynes@897
    47
   Current (2008 or later) ATI or NVidia binary OpenGL drivers 
nkeynes@897
    48
      - If anyone wants to fix the free drivers, lxdream specifically
nkeynes@897
    49
        requires a working implementation of either the EXT_framebuffer_object
nkeynes@897
    50
        or GLX_SGIX_pbuffer extensions. 
nkeynes@897
    51
nkeynes@897
    52
OS X:
nkeynes@897
    53
   System 10.4 or later
nkeynes@897
    54
nkeynes@897
    55
GCC, Make, etc.
