MSX device support: - V99x8: - fixed timing of VDP settings getting applied. This fixes the screensplit in Psycho World, Hydefos, Space Manbow and the Woei demo, and probably more. - fixed that sprites are not disabled instantly, but on the next line - Carnivore 2: - updated initial (out-of-the-box) flash content, with bootmenu 2.40 - added support for firmware version readout (now hardcoded on 2.30) - added support for SLM_cfg register - added reading from SCC, which also works on real hardware - V9990: fix location of bitmap cursor - fixed OPL4 12-bit sample decoding - fixed stereo settings of Daewoo CPC-400(S) - fixed loading/saving of flash content for ReproCartridgeV1/V2 mappers - fixed bugs in RTC (thanks to KdL and HRA!) regarding leap-year and days-in-the-month - added support for proper mapper registers readout on S1985 systems without mapper and with an external mapper that is larger than 512kB - added support for Zemina 25-in-1 mapper (thanks to BiFi and Hashem) - added new machines, thanks to: - Peter Hanraets: Victor HC-7, (partial) Hitachi MB-H2, Sanyo PHC-23J, Sanyo PHC-23 (old), Sanyo PHC-SPC, Sanyo PHC-30N, Sanyo PHC-33 (without built in tape drive features), Sanyo PHC-77, Sony HB-75, Sony HB-F700F, Sony HB-F500 (v1 and v2), AVT DPC-200, Mitsubishi ML-G10, Hitachi MB-H50 (without LEDs), Yamaha SX-100, Philips NMS 8250/19 - Arjen Zeilemaker and others: Toshiba HX-33 and HX-34 (except for the COPY button and special hardware for that) - Danilo Angel: Sanyo MPC-3 - others: Sony HB-75D, Sanyo PHC-28P - added new extensions: Popolon Sound Cartridge (with configurable size) New or improved emulator features: - by default also map the D-pad of a controller to the MSX joystick directions - fixed artifacts on 3x scaling with 512 wide MSX modes on SDLGL-PP - optimized file pool more, especially when alternative ROMs are to be found - more accurate resampling, without rounding errors - fixed possible crash when Tcl callbacks switch the active machine, e.g. using step_back in watchpoints - fixed autorun of tapes/laserdiscs interrupting the replay - fixed OMR replays with ato-run type command - faster switching to/from fullscreen, without changing the videosource - fixed laserdiscplayer eject command still showing the file inserted - make number of columns for showdebuggable configurable - fixed broken color_matrix setting (a.k.a. monitor_type) - fixed drawing of OSD progress info (e.g. while calculating hashes) - improved performance of calculating hashes of HDD images, especially when they're on a network drive - on Windows, make openmsx.exe a GUI application to avoid the separate extra text output window - added support for automatic internal conversion of SVI CAS files to WAV - added support for autoruncassettes for SVI CAS files - fixed autoruncassettes on some models like Yamaha AX150 - OSD menu: - menu button is now easy to disable with new osd_menu_button setting - removed useless frameskip controls - added full speed when loading control - tweaked special options in lists like [eject] - fixed navigating to file pools for disks - show media slot content the same way for all media - represent all media slots as slots, more similar to real hardware. You can now put both ROM cartridges and extensions in cartridge slots via the same menu - show I/O only extensions as such, as they will not take a physical slot in openMSX - allow searching also on _ and - characters in lists - show display names of what is in a media slot - show ROM info of just inserted ROM, not of the most likely running ROM - show also MSX slot number in list of cartridge slots - fixed handling of multiple identical extensions - display a message if a cartridge is removed - display the slot behind extensions in the Extension -> Remove menu - added Monitor type setting to the Video Settings menu - added OSD icon set setting to the Misc Settings menu Build system, packaging, documentation: - better support for macOS < 10.13, using HFS+J DMG format - target macOS 10.13 - build support for 64-bit RISC-V - SDLGL-PP renderer requirements are now relaxed to only OpenGL 2.1 again (was 3.3 in openMSX 16.0) - fixed building without SDL joystick support - C++ code is based on C++17 and thus requires a compiler supporting it, e.g. g++ 8 or later or Visual Studio 2019 or later - 3rd party updates of Tcl (8.6.10) and libpng (1.6.37)
