I haven't been keeping up to date with mame since 214 and I noticed that 219 doesn't echo debugger output to the console properly, instead printing a bunch of "nil"s.


I've grabbed the various mames from 215 to 219 and it seems to have started with 215.

Code

 _/      _/  _/    _/  _/      _/  _/         
_/      _/  _/    _/  _/      _/  _/_/_/_/
