Known Issues

• The MSYS2-built debugger will fail to open if launched from the Windows UI.

  • As a work-around, run it from within a CMD console.
  • Thanks to Sherman Perry for investigating this issue and isolating it to the Windows Console API.

• Audio might stutter on Some Windows platforms. If your system is affected, adjust the Mixer's settings in your conf file, as follows:

  [mixer]
  blocksize = 1024
  prebuffer = 25
  

  • Quick tip: run dosbox -editconf to open your config file.
  • Thanks to Genju for reporting this regression and isolating the solution.
