44 Version 1.9.9.1
45 ---------------
46 * Fix memory detection for 512kB case
47 * 800x600 mode
48 * Fixed timings
49 * Hint for AXP: Use -accel false -vyres -1 when changing resolution

52 Version 1.9.4.4
53 ---------------
54 * Preliminary Laguna support
55 * Overhaul color register routines.
56 * Associated with the above, console colors are now obtained from a LUT
57 called 'palette' instead of from the VGA registers. This code was
58 modeled after that in atyfb and matroxfb.
59 * Code cleanup, add comments.
60 * Overhaul SR07 handling.
61 * Bug fixes.
62
63
64 Version 1.9.4.3
65 ---------------
66 * Correctly set default startup video mode.
67 * Do not override ram size setting. Define
68 CLGEN_USE_HARDCODED_RAM_SETTINGS if you _do_ want to override the RAM
69 setting.
70 * Compile fixes related to new 2.3.x IORESOURCE_IO[PORT] symbol changes.
71 * Use new 2.3.x resource allocation.
72 * Some code cleanup.
