Hello. I'm a Noob who has learned a lot about Launchbox and RetroArch over the last week, but I have much more to learn. Bought a Launchbox full license and really love using it. I've tried this with different MAME emulators (fbneo / MAME 2016 / MAME 2013) and have the same problem with both. First, I connect my two different XBox One controllers wirelessly to my Windows 10 PC through the official Microsoft wireless adapter. When launching RetroArch, I get the message that Controller #1 and Controller #2 are found. Then, I launch a MAME game (Pacman) within RetroArch using the fbneo core. I can select credits with the "select" button from controller #1. After giving two credits, I have to use the "start" button from controller #2 to start a 2-player game. This works fine. But then, both player 1 and 2 are always controlled with the left thumbstick from controller #1 only. I have tried remapping both controllers in RetroArch, but the same problem is always there. Cannot get the thumbstick from controller #2 to work for player 2. Would appreciate any advice on how I can troubleshoot this problem. I've been working on solving it for a few days, and even after countless google searches (and searching the Launchbox forums) I have not found a solution. The same problem is there if I launch the game directly from Launchbox. As I've been working on this problem, I launch a lot directly from RetroArch just to save a few steps during constant testing. Thank you!
