Atari 2600 / 5200 - can't play 2 players games

[Patgom145]

 

Hello everybody,

 

I am discovering Atari Emulation on PC (and it is harder than I thought) and it is very nice to rediscover my childhood pleasures.

The first two systems I tries to emulate are Atari 2600 through Retroarch (Stella core) and Atari 5200 through Retroarch (atari800 core) or Kat5200.

For both systems I managed to set up my roms and my emulators and to play 99% of the games BUT I can't play 2 players games as my second controller does not have any effect.

For instance for Fall Down or Combat in Atari 2600 or Joust in Atari 5200 I can manage to play 1 player game  but not 2 players which makes me mad. In Combat it is even worse as my 1st controller makes move the 2 tanks...

What is strange is that both my controllers are detected when I launch the games :

My controllers are Ibuffalo Classic USB Gamepad which are "classic" as I think.

I have spend my two last evening trying to understand what I am missing but I have no more idea.

Many thanks for any help.

Retroarch has two levels of controller mappings.  The game controller is mapped to a retroarch controller and then the retroarch controller is mapped to the enulator controller.  Both have to be setup correctly.  There could be bugs since two player play is less common with users.  Myself I just use straight Stella and for atari 5200 I use the Altirra emulator.
