      @Riverstorm i've tried that, with the roms in the arcade folder, setting them to different emulators, via the option menu. but the tab wont work for me that way either. for some reason, they need to be in the specific mame rom folder for tab to work. im not sure if its a directory issue, or a script issue. but for me, tab only works when the roms are in the mame rom folders.. never in the arcade folder

      edit: it seems to be, because the arcade folder is using retroarch, and retroarch is overiding all settings from all the mame emulators.

      edit 2: tested again, after transferring configs from retropie 3.8.1 to the updated sd card, tab now works from the arcade folder, except when choosing lr-mame4all as the emulator

        no problem getting tab to work in lr-Mame2003 and mame4all-pi via arcade folder here. there's no difference in the folders unless in arcade you've unbound tab via the... tab menu :)

            Same here Dank, it works fine in lr-mame2003, mame4all-pi & AdvMAME. I was just trying to determine if it was broken in lr-imame4all which it looks like it is. I opened a ticket like you said in hopes it might get fixed someday. :)

              So I'm in a similar boat to others. I am predominantly running lr-mame2003 and have rooms in both the arcade and mame folder. Tab won't work for any of them. Odd thing is it worked yesterday, but last night I was setting up some games, went to hit tab and it was non existent. Tried a fresh install of retropie today and still nothing. No idea why it won't work.

                see the note on deleting to return to default config.

                  You are a wonderful, wonderful man. Thank you! I have been looking everywhere for that (which says how dumb I am cause it was right there!) Thank you!

                    @SnipedintheHead that's the configuration file. I suspect you're not running mame2003 in these instances.

                      I edited as I realized I had not touched those files. It is up and working again, thank you!

                          Hi all,

                          i have retropie 4.0.2 fresh image install and raspberry pi 3 model B.

                          i put all my roms in the arcade folder cause i like to have all my arcade games in one place.
                          Unfortunatelly the TAB mame button DONT works for all lr-mame4all emulated games ( and also fba-next )
                          but it works perfectly in games emulated with mame2003 ( both in the same "arcade" folder ) .
                          Have you got any solution to show tab menu ALSO in lr-mame4all emulated games stored in the folder "arcade"?
                          I didnt find any.
                          The strage thing is that if i put the SAME game in the lr-mame4all folder and i run the game from that emulator, then the TAB button works perfectly.
                          Is it maybe a bug?
                          Thank so much for your help

                            What is this? It doesn't exist. It is Mame4All-Pi and lr-mame4all. Which emulator are you referring to? On some emulators, TAB doesn't work.

                                @superdan Well, FBA isn't MAME, so no MAME GUI on that one for sure.

                                    The situation at the moment:
                                    lr-imame4all -> TAB not working if games are in the "arcade" folder.
                                    If the rom of the game is in the lr-imame4all rom folder than TAB works again but only in that emu, not in the "arcade" interface.

                                        tab doesn't work in lr-imame4all. if you want to use tab, use mame4all-pi, also available in the arcade folder.
