MSX device support: - fixed VDP type of Sony HB-501P - fixed a bug that caused hangups on some machines when resetting during the logo animation - fixed ROM block debuggable for Sunrise IDE - improved accuracy of WD2793 FDC and disk drive emulation - added support for Spectravideo SVI-318 and SVI-328 pre-MSX computers: - most SVI support was implemented by Tomas Karlsson. With NYYRIKKI's help we fixed most last details - added in Contrib a tool to convert SVI disk images to DMK so they can be used in openMSX - added SVI support to several scripts (thanks to NYYRIKKI): cashandler, type_via_keybuf, listing - note the following limitations: - only WAV images are supported for cassettes. The stereo feature (music/sound on the other channel) is not supported. - only DMK disk images can be used - nothing is done to prevent the user to mix MSX and SVI hardware/software. This will not work, of course. As we are not SVI enthusiasts ourselves, we rely on contributions from others for the SVI support. - added accurate M1 cycle emulation - added support for ASCII8 mapper with 32kB SRAM - added initial support for the ASCII paddle input device (paddle 1 and 2 only) - added new machines: Bawareth Perfect MSX1, Al Alamiah AX370 (thanks to alshamaa), and as already mentioned: Spectravideo SVI-318, SVI-328 and a superexpanded SVI-328. - added new extensions: Konami Ultimate Collection, ASCII Japanese MSX-Write, ASCII Japanese MSX-Write II and Tecall TM220 MSX-RAMFILE New or improved emulator features: - performance improvements: - reverse feature - hq resampler - fixed issue with remote connections on Mac OS X/FreeBSD - changed default sound driver on Windows to SDL, because the DirectX sound driver has been removed - fixed creation of new HD images - changed the default renderer to SDLGL-PP - (probably!) fixed stability of MIDI-in on Windows. Unfortunately we didn't find someone to help us test this properly - also improved stability on external connections in general - allow to specify initial content for flash ROMs. This way it is possible to use MegaFlashROMSCC+SD like how the actual hardware is also shipped: preflashed. - several improvements on the listing command (thanks to NYYRIKKI) - added automatic file numbering for record_channels - added a tron script (thanks to NYYRIKKI) - added script that records to a new AVI file if the framerate changes (thanks to BiFi and FiXato for their initial version) - added mapper selection to OSD menu for unknown ROMs - automatically pad ROM files if they are not a multiple of the block size, instead of refusing to run that ROM - added OSD button to invoke OSD menu in the top left corner - added VGM recorder script (by Niek Vlessert) to help you record MSX songs into VGM files, supporting PSG, MSX-MUSIC, MSX-AUDIO, OPL4 and SCC Build system, packaging, documentation: - migrated from SDL threads to C++11 threads - removed support for Maemo5 - moved Windows build to Visual Studio 2017 - upgraded C-BIOS to release 0.28

- Improved emulation of Trakball controller, eliminating bias in left/ right directions. Thanks to Thomas Jentzsch for the idea and code. Related to this, added 'tsense' commandline argument and associated UI item, to allow changing sensitivity of mouse trackball emulation. - Added preliminary support for multi-threading in the Blargg TV effects code. This is still a WIP; more improvements are coming. Related to this, further optimized the TIA rendering code. Also added 'threads' commandline argument and associated UI item to enable/disable multi-threading. Thanks to Thomas Jentzsch for the bulk of the work in this area. - Blargg TV effects now no longer cut off the right side of the image (by several pixels) in certain cases. - Updated CDF scheme to latest version from Spiceware. In addition, this scheme now supports versioning, so older and newer ROMs will continue to work. - Fixed an annoying bug in Linux, where Alt-Tab'ing out of a window and then back again would pass a 'Tab' key event to the app, which in most cases would navigate to the next UI element. - Fixed potential issue with state file saving and the debugger; under certain circumstances a rewind would give a different state than before (note that the state file format has changed because of this). - Fixed lockups when entering the debugger under certain circumstances. - The debugger 'listtraps' command now shows all traps set, not just the first one(s). - Reverted joystick changes for Decathlon ROMs from last release, as it was added by mistake.

Bug fixes: - Breakpoints now trigger on both addresses of a 16-bit memory read or write. Enhancements - Updated ZXpand emulation to use the ROM and firmware of the ZXpand+ model. AY sound is not automatically selected. - ROM files have been renamed to follow a consistent scheme: [system].[modifier](.[modifier]...) - A Save option has been added to the TZX Edit General Data Block window to allow saving of ZX80 and ZX81 programs. - The character representations of the data shown in the TZX General Data Block window can now be viewed using the ZX80 character set.

- With Windows8/10 when "Play Installed CD" is selected, fixed the problem that Ootake stopped. - When "Sorcerian" is started, the title screen is launched immediately. (launched with [I] button pressed) If you do not need this, please uncheck [Adjust Sorcerian BGM Repeat] of [Setting->Improve] menu. - [Auto Skep Opening (Sorcerian)] was added to [Setting->Improve] menu. If this menu is checked, when "Sorcerian" is started, the title screen is launched immediately.(launched with [I] button pressed). By default this is off. + When this menu is checked, if you reset the game with [SELECT]+[RUN], you can see the opening demo. - In "Sorcerian", when the party returned to the castle, fixed a problem where BGM was disturbed. - The operation of the PCE built-in sound (wave memory sound) has been brought close to the real machine. In "Xevious - Fardraut Densetsu", when PAUSE was released, the problems that sound became thin was solved. - When "Gotzendiener" is started, it is starts with Multi-Tap removed. The problem that the motion was unstable has been solved. (This problem will occur in the same way on the real machine) - Additionally, a detailed part has been improved and corrected.
