Keyboard TAB key not working in MAME/Retroepie

[dankcushions]

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!

[dankcushions]

@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

mame-mame4all

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]

You are right. its lr-mame4all and also fba-next. Sorry but i dont have mi pi with me

[caver01]

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

[superdan]

Thanks caver,
so is actually not possible to configure mame's dip switch under lr-fba-next?

[superdan]

Thanks for your replies,
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.
