@kjgregory83 you might want to try out redream. For now it has better performance/compatability on the pi 4 then flycast does and controller mapping is a breeze.

@skrilmps said in can't access MAME 2003+ (libretro) in-game menu: cy no problems at all always use then menu to set options code can change any time.

@mitu I have the exact same issue (I made a post about it [here(https://retropie.org.uk/forum/topic/26598/problem-with-controller-mapping-being-different-in-games-and-menu)). If you’re able to help: I use a RPi 3 b+ with a pre made SD image (v. 4.6) from the official Retropie website. I am using a wireless Arrogant Bastard controller with dongle.

@uraverageplayer What emulator/game are you starting when it's not working ? Configuring the joysticks in EmulationStation would automatically create a configuration for RetroArch based emulators (the ones that start with lr-), but certain emulators are not auto-configured (i.e. advmame or mame4all).

@archie456 Please add more info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

@mitu I just did it and now seems to work correctly. Thank you. I'll let you know if I get other issues

Yeah I wouldn't think so either, but it totally works with 6 button in Picodrive

@lesk Deopending on the emulator and version I think, as it is a relative recent feature. You may need to update RetroPie. There are entries in the emulator menu for this feature: SETTINGS > LATENCY. I looked up in Snes9x 1.56.2, Nestopia 1.50-WIP and MAME 2003 (0.78). The Raspberry Pi 3 is too weak and it would be extremly slow and painful (as far as I know). Which emulator and version do you want use this for? Try the "lr-" versions.

@BuZz I did

I have modified the values in RetroPie and in Raspbian. Thank you. It's fixed. I just hope this doesn't have a significant impact on other activities on the Pi sucj as simple web browsing.

I finally used the retroarch menu (Select+X) and remapped the controls here. It works fine. I think that the problem was the special syntax for Vectrex.

@katzumoto Actually, many "different" standard usb devices have the same chips and/or firmware in them and thus, register as the same product in the system. Setting up the xboxdrv is thoroughly described in the link from @mitu two posts above yours. Although you may have to read all of it to setup the driver, section 2C deals with renaming for separate identification of multiple identical controllers. You should work through the instructions and then post any remaining questions or obstacles that come up in a new thread about your problem. Its usually better than using an old thread from someone else, even if it's thematically related.

@IanDaemon i found that when I'm in game and I bring up the retroarch menu, I can't move anything in the UI. The cursor will not move with keyboard or controller. I'm stuck there until I hard reset the pi because I have no input. I thought about a reinstall but I spent a lot of time scraping and setting up and I'd hate to have to do it all again.

I seem to have fixed this. I found a page (here) with a few extra instructions on suppressing various messages. I haven't implemented them all but it seems the one or two I have added have done the trick! I'd already added one or two of these as per the excellent Retropie docs, but the extra bits here seem to have done the trick. Been mashing about the menu for a couple of hours, and rebooted several times and so far it has not returned. Thanks for your help. Thrilled to get it working so nice! :-)
