FYI user ‘iso70x’ posted the following in the GitHub issue thread:
It looks like there's a slight mistake in the c:\autoexec.bat file in the monkey island 1 mt32 vhd. If I replace MONKEY.EXE with RUNGAME.BAT it fixes it and uses mt32. RUNGAME.BAT launches the game with the additional switch needed to use mt32.
I am new to Mister and have been really enjoying this great collection of DOS games. Thanks for all the efforts for those involved in developing this! Just an FYI it seems that the MT-32 version of Monkey Island is not working with the MT-32 pi. Sound works fine but it is not using the MT-32 pi.
Thanks for the replies! I hadn’t really considered that the issue was with the 0mhz version since they have all worked so flawlessly for me. Cheers again for responding.
