CHD Based games not launching?

CHD Based games not launching? - 07/12/17 11:27 PM

So I'm not sure if this is a problem with my configuration, a Mac specific problem, a problem with QMC2 0.186 that'll be fixed in 0.187, or something else entirely...

Attempting to launch (almost) any CHD based game via QMC2 0.186 (with MAME 0.187) results in the game not launching, and the emulator log stating the following:

18:20:33.507: stderr[#0]: area51.chd DIFF CHD ERROR: file not found
18:20:33.509: stderr[#0]: Fatal error: Required files are missing, the machine cannot be run.

Ordinarily, I'd figure that I had a corrupt/outdated CHD file, and act accordingly.

However, attempting to launch the same game with a different front end (MAME Tunes, in this case, which is outdated, but still serves some functions) successfully launches the game.

Has anyone else run into this problem, and if so, is there a workaround?

It looks like your diff-directory isn't set correctly, that is, I assume that you didn't specify the emulator's working directory in QMC2 or the "diff_directory" setting is wrong.
