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!

128 -------------------------
129 * Speed improvements (translation core now runs at roughly double the speed
130 of M3)
131 * GUI Overhaul - it's actually somewhat usable now. Also removed the gnome
