MESS v0.79

posted in Emulator Release by narvick on Feb 20th, 2004

MESS, the Multi Emulation Super System, has been updated to v0.79. Here's what's new:
    New System Drivers Supported
  • [MSX2] Sony HB-F700P
  • [MSX2] NMS 8245 and NMS 8255
  • [MSX] National FS-4000
  • [MSX] Sony HB-75P


  • System Driver Changes
  • [APPLE2] Fixed a regression in caching disk data that would cause data to be lost when switching disks, or for switching disks to not be acknowledged
  • [MSX] Rewrote memory emulation
    • Adds support for subslots
    • Proper memory layout for the MSX2 drivers, with the diskrom in a subslot of slot 3
    • Adds support for Konami's Sound Cartridge (128kb)
    • Adds support for Korean 90-in-1
    • Adds support for Kanji ROM

    If no cartridges are supplied, it sets the sound cartridge in slot 1 and the FM-PAC in slot 2. The Snatcher, SD-Snatcher and the Konami Game Collections now work. Note that Sound Cartridge also behaves as a normal SSC

    With one cartridge supplied the FM-PAC is still set in slot 2 so R-Type and other ROM cartridges can still use it

  • [SUPERBRD] Updated driver with a better BIOS set and keyboard layout and added sound


  • User Interface Changes
  • [Windows GUI] Minor bug fixes regarding software listing and CRC calculations with respect to clone and compatible drivers


  • Source Changes
  • The core is based on MAME v0.79. This incorporates all features of the update to this core
  • As a consequence of the MAME v0.79 core, which has massive changes to the memory system, there is a greater likelyhood of regressions in this MESS release (as with MAME)
  • Introduced automated messtest testing facility, in order to prevent regressions in the future
  • Internal error reporting enhancements for image loading; still some work to do
