Hi guys I've got two problems, one caused by trying to fix the first one. I would like to ask some experienced help please. I'm using MAMEUI 146 and newest version on GameEx with iPac/keyboard (WinXP). I'm at the end of my arcade cabinet project and just need to sort out these two issues. Problem 1. When I'm in a MAME game, upon pressing the GameEx Input Settings configured "back button", the game exits and returns to GameEx. I suspected that the problem came form the Input Settings, but after removing the "Back button" setting in GameEx, the problem persisted. I've then gone and started to look at the MAME Configure setting (Tab triggered) to see if these buttons are not double configured to exit, and that is where problem 2 started. Does anyone have an idea where this problem can be coming from other than the input settings? Problem 2. Upon going through the MAME configuration settings, I started to none-fy the unused buttons. I've stupidly also made the MAME UI_CONFIGURATION button (usually Tab) have no key. Now I can't trigger the configuration menu anymore. Does anyone know how I can reset these settings externally, or what/where the ini or cfg file is situated that contains the MAME UI_CONFIGURE input setting? (Remember its for keyboard, not hotrod, etc.). Thank you in advance
