Hi there- I'm running into an error I can't seem to resolve. For a little context, I'm on Windows 10 running LaunchBox 13.24 and I've got my ROMs sitting on an external HD in their own folders (e.g. R:\Arcade\Sega Genesis\roms) outside of the LaunchBox directory (which is on the same external HD, R:\Arcade\LaunchBox), and have imported all of my ROMs in the same way using Tools>Import>ROM Files>Single Platform. Arcade ROMs are running on MAME, and console ROMs are running on RetroArch. Here's my problem: I click the "More Options" (3 dots) menu below a ROM (for example in the Super Nintendo Entertainment System platform), then click "Configure", and I receive an "An error occurred while trying to launch the game: Object reference not set to an instance of an object." error. I've tried Tools>Download>Force Update Games Database Metadata to no avail. I can play the ROMs just fine, so this isn't a critical error, just something I stumbled upon and found strange considering everything else works as expected, as far as I can tell. Something else I don't understand is that for certain platforms, e.g. Sega Genesis, clicking the 3 dots menu on a ROM only gives the option to "Delete" and doesn't have the "Configure" option at all. TIA to anyone who can shed any light on this.

This issues has been driving me nuts for weeks. I can’t seem to figure it out. I’m trying to configure Retroarch for the first time. I want to use it to emulate NES, SNES, Sega Genesis, etc on my Arcade. The arcade has an Xtension 2 player control panel, configured for keyboard inputs. Works just fine with MAME games & the standalone MAME emulator. But I’m just focusing on NES & Retroarch for now. This should be simple, since I just need to enter control inputs for up, down, left, right, A, B, Start & Select. I just can’t figure out Retroarch. I’ll load the NES core in Retroarch (NestopiaUE), then go to Input and then Input User 1 Binds. I assume these are the general inputs for Retroarch overall. Not sure if I need to setup a config file for each core tho. This should be simple, but it’s not. I head down to the User 1 D-pad settings. The correct settings should be up, down, left, right arrow keys. When I press enter to change & then press down on my joystick, the key is changed to keypad2, not down. So all my settings are set to keypad8, keypad2, keypad4, keypad6. It doesn’t matter if I enter inputs with the joystick or arrow keys on the keyboard. Doesn’t matter if the keyboard number lock is on or off. So when I launch an NES game, the joystick controls do not work. I’m at a loss how to fix. I suppose I could manually change the config file in notepad++, but I cannot locate the config file on my hard drive, and I’m not sure if config files need to be made for each core. And if individual config files need to be created, how do I get them to launch with each Retroarch core? Setting up my Arcade has been a ongoing battle every step of the way. So damn frustrating. This shit is going to take me years. Any help appreciated.

FYI: Noob here.... I have managed to setup Retroarch on Launchbox; however I am not able to play games accurately on my laptops keyboard as there is no configuration that I can access for the keys, it seems the option is grayed out. The only working keys for games on my keyboard I believe are: X, C, R, P (pause) Space (reset) and Shift, but I do not have access to a directional Pad either UP, DW, Left and Right don't do anything when pressed. Do I have to buy BigBox as the only way to access this configuration option ??? Please Help... Also I have tried a PC controller (PS3 style) from GameStop with no luck, but I anin't worried about that now.. If someone can guide me on a how to setup a keyboard Launchbox that would be highly appreciate it. Thank you
