BADsDAD Posted July 20, 2018 Share Posted July 20, 2018 Hi all, I have this issue that if I launch Mame roms through LaunchBox, I get an error message "Illegal boolean value for sound; reverting to 0" and I then get no sound. If I launch natively from Mame GUI, this doesn't happen and sound works fine. Any recommendations on what I might try to fix this? Thanks!

Lordmonkus Posted July 20, 2018 Share Posted July 20, 2018 I have never seen that error and a quick Google search turns up nothing. My first and only guess at this point in time would be something with the version of Mame you are using not liking the idea of launching a rom via command line. That is purely a guess though.

BADsDAD Posted July 20, 2018 Author Share Posted July 20, 2018 Well, it is Mame 0.122u1 so it's really old, but I haven't seen how I can easily update my romset from the current version or even tell what version it is very easily in order to run a newer Mame. I did read the sticky on updating them, but it is mentioned even there that there is no easy way to tell the version of the currrent romset. Do you know of a way? If they are as old as the Mame version than I can't imagine doing that many updates anyway. If I were to acquire roms for the newest version of Mame, can I just add another platform in Launchbox and run the newer roms and Mame out of that without impacting anything else, just by naming that a different platform name?

Lordmonkus Posted July 20, 2018 Share Posted July 20, 2018 My advice would be to just get a new and updated rom set and Mame build to go along with it, that would be the simplest. Quote Link to comment Share on other sites More sharing options...
DOS76 Posted July 20, 2018 Share Posted July 20, 2018 yeah I would have to agree rebuilding your set with all the packs from 122 up to current would probably prove to be difficult. It would probably prove hard to find all the update packs that far back best bet is to go over to Pleasuredome.org.uk and download the latest set there.

BADsDAD Posted July 20, 2018 Author Share Posted July 20, 2018 Thanks guys, Do you know if they offer something like a top 100 games pack or similar, my ISP kinda sucks and I really only play the more popular ones anyway. Quote Link to comment Share on other sites More sharing options...
Lordmonkus Posted July 20, 2018 Share Posted July 20, 2018 They don't unfortunately. Quote Link to comment Share on other sites More sharing options...
CTRL-ALT-DEFEAT Posted July 20, 2018 Share Posted July 20, 2018 Can't offer solving that issue but, a Boolean value is binary/true or false. I had to learn Boolean Algebra in electronics and it is comprised of only using 0's (false) and 1's (true). So it would make sense that 0 would result in no audio for this error, but not sure why it is reverting to this unless the value that is set for that ROM is something other than 1 for "on". Perhaps set to a value of 2 or more, which would be illegal. Quote Link to comment Share on other sites More sharing options...
