Retropie 4 retroarch controls changing

[ruxton_bruce]

After updating to Retropie 4 my controls in Mame-Libretro games go all screwy. If I replace the /opt/retropie/configs/mame-libretro/retroarch.cfg file with an older backup that I had with Retropie 3 the controls work fine once then launching the same game afterwards makes the controls go all screwy again.

E.g

When I launch Metal Slug 2 with the retroarch.cfg file from the old Retropie 3 backup all button on an ipac2 controller work fine.
When i relaunch the games Button three changes to the normal button three plus the insert coin button.

Any help much appreciated.

Cheers

Please post the backup retroarch.cfg file you use on pastebin.

@Floob Hey there Floob

Thanks for the reply mate. I replaced the retroarch file that you supplied in this post:-

and everything is back to normal.

Thanks heaps for all your help mate.

@Floob Hey there Floob. I just noticed that I still have a problem with the controls in Mame-Libretro.

When I launch a 2 player game such as The Simpsons, Player 2's button 1 also makes Player 1's button 2 trigger. I am using an IPAC2 controller and I have tested it with the keyboard with the same results. My /opt/retropie/configs/mame-libretro/retroarch.cfg file looks like this:-

I have tested 2 Player games with mame4all and don't have any issues so the problem must be with retroarch.

Any ideas why this might be happening mate?

Sorry to be a pest - just can't wrap my head around Retroarch controls very well.

Cheers @Floob

@Floob Please disregard my last message Floob. I found in /opt/retropie/configs/all/retroarch.cfg that I needed to adjust the Keyboard Input section in there. Mine was set to:-

input_player1_a = "x"
input_player1_b = "z"
input_player1_y = "a"
input_player1_x = "s"
input_player1_start = "enter"
input_player1_select = "rshift"
input_player1_l = "q"
input_player1_r = "w"
input_player1_left = "left"
input_player1_right = "right"
input_player1_up = "up"
input_player1_down = "down"

I needed to change it to this to fix my problems:-

input_player1_a = "lctrl"
input_player1_b = "lalt"
input_player1_y = "ralt"
input_player1_x = "space"
input_player1_start = "1"
input_player1_select = "5"
input_player1_l = "q"
input_player1_r = "w"
input_player1_left = "left"
input_player1_right = "right"
input_player1_up = "up"
input_player1_down = "down"

If you have any suggestions to a better mapping I'm all ears :)

Cheers @Floob

Quick note - I needed to change

input_player1_l = "q"
input_player1_r = "w"

to

input_player1_l = "("
input_player1_r = ")"

as q and w are used for games with more than 4 buttons such as Street Fighter Alpha 3.

Will the quotation marks causes any problems for retroarch anywhere else @Floob

Thanks again
