I have an IPAC2, As well as an IPAC4 They are coded this way below (in addition to my RetroArch config below). However when I'm using only certain versions of MAME I think it's either 2000 libretro or MAME 2014 libretro on a raspberry Pi. My issue is when I hit "UP" on Player 2 joystick the MAME GUI pops up ! Which should be triggered by TAB...(Tab also triggers it which I obviously want it to). But I don't understand If IPAC is coded to use "R" as up on P2 Joystick how is that triggering the TAB/MENU system on MAME ?! I don't have this issue when using MAME 2003 (.78 Set). I'm using various versions of MAME to support the best game play / emulation. Below is also a portion of my RetroArch config which seems to override take control of the controllers. I have a work around which essentially I can use something other than "R" for Player 2 up, simply I can reassign the key / reflash the IPAC to something else but I think this can be resolved via software / or a config file. Any one care to chime in as to why Player 2 UP which is "R" on my IPAC causes the MAME GUI / TAB to appear on the screen !? Is this a known issues in Libretro MAME where "R" pulls up TAB MAME GUI ?

RetroArch portion of my config (from my 2-player build)
input_player1_a = "alt"
input_player1_b = "ctrl"
input_player1_y = "shift"
input_player1_x = "space"
input_player1_start = "num1"
input_player1_select = "num7"
input_player1_l = "z"
input_player1_r = "x"
input_player1_left = "left"
input_player1_right = "right"
input_player1_up = "up"
input_player1_down = "down"
input_player2_a = "s"
input_player2_b = "a"
input_player2_y = "w"
input_player2_x = "q"
input_player2_start = "num2"
input_player2_select = "num6"
input_player2_l = "i"
input_player2_r = "k"
input_player2_left = "d"
input_player2_right = "g"
input_player2_up = "r"
input_player2_down = "f"

  • Plenty of skills.. gaining experience..
Did you check this in Notepad and with a keyboard?
A couple of times on my build I thought I had an iPac problem and it wasn't.  Try a keyboard and hit 'R' and see if you have the same issue..  w/o the iPac USB plugged in..
