I just looked and the latest version of a Debbugger that is available dates back to around 0.125. Is there a newer debugger available with the current MESS?

Thanks.

MAME/MESS always come with the debugger now. Use -debug from the commandline or check the relevant option in the GUI.

Thanks for the info. I don't know what I was doing wrong, but I couldn't get the debugger to run from the Windows GUI this morning, but this evening it works. I could get it to run from the command prompt this morning. Not sure what I was doing wrong as I checked several boxes in the debug tab and nothing came up this morning. Then, this evening after running the command line version, the WinGUI version works.
