BletchMAME

BletchMAME is a new experimental front end for MAME. Unlike existing front ends (which function as launchers, keeping MAME’s internal UI), BletchMAME replaces the internal MAME UI with a more conventional point and click GUI to provide a friendlier experience in a number of areas (such as profiles, input configuration and a number of others). While BletchMAME is intended to support all machines supported by MAME, it should be particularly suitable to computer emulation.

Running BletchMAME

To run BletchMAME, run the installer (BletchMAME.msi on Windows) and BletchMAME will install, or install manually from the ZIP file. The first thing you must do is point BletchMAME at a locally installed version of MAME 0.213 or later. BletchMAME will take some time to read info from MAME, and when this is complete you can run the emulation.

  • Beginings of a MAMEUI-style machine folder and snapshot view
• 2.4 (2021-Jan-3)
  • Updated various parts of the worker_ui plugin in response to breaking LUA changes in MAME 0.227
    • An implication is that previous versions of BletchMAME will not work with MAME 0.227 or greater
    • Because MAME 0.227 doesn’t support hot changes to mouse capture, the mouse may not be usable
      • BletchMAME will warn the user in this scenario
  • Changed the Images Dialog to a Configurable Devices dialog, combining image and slot selection
    • Slot modification requires MAME 0.227, and will not function in previouew versions
  • Resurrected the “Quick Load/Save State” feature, which has been broken since 2.0
  • Fixed profile renaming, which also has been broken since 2.0
  • Fixed a bug in the profiles view that could cause a crash if one right clicks empty space
• 2.3 (2020-Dec-13)
  • Added a warning to the Images Dialog if no hash paths were set up
  • Fixed a bug that could cause image widgets to not be properly cleaned up if they got removed by a slot change
  • Fixed a bug that prevented the “Unload Image” menu item from working
  • Fixed a bug in the console window that could cause text to be appended in the wrong location
  • Fixed a cosmetic bug in the “About BletchMAME” dialog
  • No longer passing -nodtd when invoking -listxml on MAME
  • Changed worker_ui plugin to tolerate changes in machine().images expected with MAME 0.227
• 2.2 (2020-Oct-3)
  • Support for cheats (requires MAME 0.225)
  • The worker_ui plugin is now tested automatically as a part of the CI/CD pipeline

• 2.0 (2020-Aug-23)
  • Overhaul of BletchMAME application
  • Transitioned from wxWidgets to Qt
  • Adopted CMake
  • Unit tests now executed as part of build pipeline
• 1.9 (2020-May-20)
  • Added the ability to record AVI/MNG movies (requires MAME 0.221)
  • Fixed a bug that would choose odd default file name when saving screenshots
  • Ensuring that directory paths always have trailing path separators
• 1.8 (2020-Feb-16)
  • Added command to drop into debugger
  • Fixed menu bar toggling bug
• 1.7 (2019-Dec-28)
  • We have a real domain name (https://www.bletchmame.org/); added a menu item to go directly there
  • If we fail to start MAME, we will now crudely present MAME’s error message to the user
  • When supported by MAME (0.217 dirty or greater), we will attach to a child window rather than the BletchMAME root window. This fixes a bug where the status bar could obscure part of the running emulation
• 1.6 (2019-Nov-24)
