openMSX 0.12.0

Description

openMSX is an open source MSX emulator which is free according to the Debian Free Software Guidelines, available under the GNU General Public License.

 

For copyright reasons the emulator cannot be distributed with original BIOS ROM images. OpenMSX includes C-BIOS, a minimal implementation of the MSX BIOS, allowing some games to be played without an original MSX BIOS ROM image. You can also use your own BIOS ROM image if you please.

 

OpenMSX uses a distinctive emulation model to achieve the highest level of accuracy possible. It is available for multiple platforms including POSIX and Microsoft Windows operating systems and emulates a large amount of MSX (related) hardware, including:

  • MSXturboR
  • Moonsound
  • IDE Controller by Sunrise
  • GFX9000
  • Pioneer Palcom LaserDisc

 

Notable features include:

  • Hard- and software Scalers
  • Debugging
  • Tcl Script Support
  • Cheat Finder (through Tcl)
  • Game Trainers (through Tcl)
  • Audio/Video recording
  • Reverse support (go back in emulated time to correct mistakes or debug what happened)

 

OpenMSX has an open communication protocol to communicate with the openMSX emulator. Utilizing this communication protocol enables to write versatile add-ons for openMSX. Projects making use of this protocol include the following applications:

  • openMSX Catapult (by the openMSX team)
  • openMSX Debugger (by the openMSX team)
  • openMSXControl plugin
  • NekoLauncher openMSX
  • openMSX Peashooter
  • openMSX Control Plugin for Gedit

 

Currently Catapult, a GUI developed for the emulator that is part of the project, is being redeveloped utilizing Python and the Qt toolkit.

 

The openMSX Debugger is also under development, written in C++, also utilizing the Qt Toolkit.

Changelog

This was going to be (mostly) a bug fix release. But at the end we also got inspired by Grauw to add a lot of MIDI devices. And, reviewing what we changed the last 10 months, we saw that we also got loads of help from several people to add many new machine configurations and added some fun stuff like Sensor Kid and (experimental) Beer IDE emulation. On the emulator features category we give you stuff like triplesize video recording, some TAS enhancements and a callback for too fast VRAM access. So, enjoy this 'various features and bug fixes' release!

Here's the list with all highlights and details:

MSX device support:

  • fixed (S)RAM writing on turboR
  • fixed border color in screen 11/12
  • fixed some details of SD card emulation (found with FUZIX)
  • fixed clipping bug in sprite-mode-1 drawing
  • fixed crash in openMSX when using the AVT DPF-550 extension
  • fixed support of 8kB RS-232C ROMs (which is the only correct size!)
  • fixed emulation of joystick mode of the mouse
  • fixed broken MegaFlashROM SCC+ (introduced with openMSX 0.11.0)
  • improved trackball movement emulation so that JoyTest can also detect it like on real hardware
  • fixed touchpad joystick pins (fixing detection in JoyTest)
  • tweaked volumes of SFG-01/05 against the PSG
  • added Panasonic FS-A1WSX/WX variant ot the MSX-MUSIC mapper
  • added proper YM2148 emulation (MIDI in/out for Yamaha SFG modules)
  • added proper MC6850 emulation (MIDI in/out for Philips Music Module)
  • added emulation of FAC MIDI Interface
  • added emulation of Sensor Kid, ported from yayaMSX2SK, which is based on Mr. Takeda's Common Source Code Project
  • added emulation of BeerIDE (experimental)
  • added many new machines: Canon V-25 (thanks to Rudi Westerhof), Canon V-8, Fenner/Samsung SPC-800, Hitachi MB-H1, Toshiba HX-10D (thanks to Ricardo Jurcyk Pinheiro), Canon V-10, Canon V-20 (JP), Spectravideo SVI-728 (ES), Mitsubishi ML-TS2 (partly, it's still work-in-progress), Sony HB-101 (JP), Sony HB-201 (JP), Sanyo MPC-6, Mitsubishi ML-F120 and ML-F110 and Hitachi MB-H3 (thanks to Werner Kai) and Yamaha AX350IIF (thanks to Rudolf Gutlich)

New or improved emulator features:

  • added "too_fast_vram_access_callback": you can now run a Tcl script when the running MSX software accesses VRAM too fast, e.g. break to debug
  • added display of 'movie length' in TAS mode. This is the length of your 'movie' if you upload it to tasvideos.org
  • added -triplesize to video recorder: allows creation of video files in 960x720 pixels, for which YouTube renders videos at 60 fps.
  • some fixes in keyboard mappings
  • fixed slow console when emulation speed is very low
  • add a snapshot 'near the end' to the OMR when saving it, allowing quicker continuation of the replay after loading it
  • similarly, add snapshots when fast-forwarding to the target time, so they can be used to jump back more quickly
  • show reverse bar in green when replaying in viewonly mode
  • added a converter from/to OMR to/from text, which allows you to more easily edit the OMR outside of openMSX
  • improved implementation of 'auto-save' feature of replays: the setting will now persist over openMSX sessions
  • added an OSD overlay for Metal Gear

Build system, packaging, documentation:

  • replace mingw32 build support with MinGW-w64 build support on Windows
  • updated our website and other URL's to point to http://openmsx.org/ or GitHub

And of course the usual various bug fixes and performance improvements.
