OpenMSX v0.9.0 Changelog:

This release improves a lot on accuracy of floppy support, especially by the introduction of support for the DMK format. This means it should be possible to run all MSX disk software without patching it. Furthermore, our efforts to improve performance has some results: start up time has almost halved on a Dingoo A320! Here's the list with all highlights: MSX device support: - Bug fixes: - overscan: 512x512 demo by NYYRIKKI and Don't Cock It Up by Matra now work - cursor order in B-modes of GFX9000 - several small issues in existing MSX machine configurations - broken border rendering on ARM CPU's - 2nd drive detection on National machines - detail in MSX-AUDIO that prevented proper detection in MSX-AUDIO BIOS 1.3 - Accuracy improvements: - much improved accuracy for Floppy Drive Controllers (mostly WD2793 and alike) - added support for delayed motor off for disk drives, as in real machines implemented by the CXD1032 chip - disk drive rotation is now correct - added support for persistency of S1985 back-up RAM - added support for specifying the initial content of RAM and VRAM. Fixing this for the Philips MSX2's shows why Cas Cremers never noticed a bug in Akin, causing white pixels on the screen - Added initial support for Video9000: - new extension, which gives a new Video9000 videosource - the Video9000 can display the GFX9000 output superimposed over the normal VDP. Software which writes to I/O port 0x6F when a Video9000 is connected will make sure the right video signal is displayed. This is now emulated. So, use the video9000 extension instead of the gfx9000 extension to benefit from Video 9000 aware MSX software! - added video recording for Video9000 videosource - Added support for the FDC connection style of the Victor HC-9x - Added support for several floppy drive extensions: Sanyo MFD-001, Mitsubishi ML-30DC/ML-30FD, Talent DPF-550, AVT DPF-550, Philips NMS 1200 - Added Spanish Mitsubishi ML-G1, Spanish Mitsubishi ML-G3, Japanese Sony HB-10 and Talent TPC-310 machines New or improved emulator features: - MSX developer features: - more mappers now have a romblocks debuggable - added several new procs for break point conditions: address_in_slot, watch_in_slot - you can now have breakpoints and watchpoints anywhere in a MegaROM - previously hardcoded warnings for invalid PSG directions and di;halt detection are now a Tcl callback, which means you can e.g. let openMSX go into a break point when they occur, or disable them altogether - save_debuggable can now also save part of a debuggable - Console support/scripts: - added type command that can type from file and a special version with offset to type passwords) - added syntax highlighting for Tcl in the console - show errors in the console in red - implemented tab-completion for nested Tcl commands - OSD menu improvements: - list of machines and extensions are now sorted alphabetically - file lists are now filtered on extension case insensitively - Performance improvements: - OSD - start-up time - several scripts (reverse bar a.o.) - Miscellaneous: - guess_title script is now a lot better and is used to generate file names if no file name was given (e.g. to screenshots) - reverse bar has now even clearer colors to reflect recording (red) and replaying state - don't print an error when an initial CMOS/SRAM file isn't found - enable auto-run for cassettes by default - show an error message when using harddisk images larger than 2GB, because that is currently not properly supported - show progress on calculating SHA1 sum of large harddisk images - additional files for ROMs (like samples for Playball) can now also be in the same directory as the ROM file Build system, packaging, documentation: - Upgraded 3rd party libraries - Removed support for PPC on Mac and added build support for clang, which is also our new default compiler for Mac OS X - Added several utilities for DMK support: dumping tool, analyzing tool, creation tool and conversion tools - First step in phasing out the roms/ directories: removed them (including SHA1SUMS file which was redundant with the hardwareconfig.xml files) and new configs do not use the path with roms/ anymore; use the systemroms pool instead And of course the usual various bug fixes.
