I am trying to set up a system that can play both Supermodel and MAME via Retroarch.
The problem I have run into is that the only way I have found to exit Supermodel is to set a button on my controller to "close active window" in Launchbox. This works swimmingly for Supermodel, but is causing set up headaches in Retroarch. The arcade controller only has 6 buttons and it would make setup MUCH easier if there was some way to enable one of those buttons to exit Supermodel only. Exiting Retroarch with 1 button is problematic when that effectively leaves me with 5 buttons.
