     1 Release notes for lxdream 0.9.2 "Slippery Turtle"
     2 ===================================================
     4 Lxdream 0.9.2 primarily focuses on improving rendering performance, which is
     5 up to 3x faster than 0.9.1 (depending on hardware and scene details). The
     6 CD-ROM device layer has also been rewritten to provide more flexibility and
     7 introduce some new features. 
     9 Nevertheless this should still be considered an alpha release, with many 
    10 unimplemented features remaining. You're unlikely to see 'perfect' emulation,
    11 and we're nowhere near being bug-compatible (in other words, don't expect your
    12 code to work on the real hardware just because it runs correctly in lxdream).
    14 Note that command-line options for running binary executables have been changed in this
    15 release:
    17    lxdream -e homebrew.bin
    19 will load and execute the binary directly, while
    21    lxdream homebrew.bin
    23 will now embed the binary into a bootable disc image, and then boot into the 
    24 disc.
    26 Changes since 0.9.1
    27 -----------------
    28 * Lots of tuning of rendering performance.
    29 * Can now boot and run homebrew discs without requiring the BIOS rom image.
    30 * Automagic wrapping of executable files in disc images.
    31 * New dependency on libisofs
    32 * Minor bugfixes
    34 Known issues
    35 ------------
    36 The following are known problems in 0.9 that will be fixed before 1.0 - 
    37 in other words, you don't need to report them - we already know :)
    39 * Graphic artifacts related to translucent triangle intersections, sorting errors 
    40   and/of lack of depth precision.
    42 * The SH4 emulation is not cycle accurate, and (by default) usually runs
    43   slower than the real one. This cause some programs to have timing problems
    44   or to break completely. In some cases this can be worked around by
    45   adjusting the CPU scaling factor (-m command line option)
    47 * Audio quality generally ranges from poor to horrible, interrupted by the
    48   occasional bit of fair-to-middling sound. 
    50 System requirements
    51 -------------------
    52 Linux:
    53    GTK 2.6+
    54    Current (2008 or later) ATI or NVidia binary OpenGL drivers 
    55       - If anyone wants to fix the free drivers, lxdream specifically
    56         requires a working implementation of either the EXT_framebuffer_object
    57         or GLX_SGIX_pbuffer extensions. 
    59 OS X:
    60    System 10.5 or later
    62 GCC, Make, etc.
    64 Building
    65 --------
    66 From the base directory
    67 ~$ ./configure
    68 ~$ make
    69 ~$ make install            (optional, GTK only)
    71 Enjoy!
