Has anyone gotten multiplayer to work in Atari 2600 games?

RetroArch General
#1

I’ve been trying for hours to get multiplayer working on Atari 2600 games. I believe my config file is correct, but when i load a rom I can’t control player 2 at all.

Here’s my retroarch.cfg:


input_player1_a = x
input_player1_start = q
input_player1_select = w
input_player1_left = up
input_player1_right = down
input_player1_up = right
input_player1_down = left

input_player2_a = h
input_player2_left = c
input_player2_right = r
input_player2_up = v
input_player2_down = f

input_enable_hotkey = s
input_exit_emulator_btn = b

Has anyone gotten multiplayer to work on Atari? This is driving me crazy. I’m running RetroArch on a Raspberry Pi running Raspbian, and I’m using two wii remotes for controllers (hence the weird keybindings).

This is using the Hatari core? If so, I don’t think it’s considered “finished” yet. As such, you’re likely to run into issues like that.

#3

Nope, I’m using the stella-libretro core. I’ve actually been using Emulation Station as a front end, but I’ve tried launching the game through Emulation Station and through RetroArch itself and they both produced the same results (I can’t imagine Emulation Station is interfering though)

Oh yeah, I totally forgot about Stella.

Yeah, seems to be doing the same thing here using the version from Phoenix updater.

#5

Alright, so I finally got some time to sit down and work on this, and I’ve fixed the bug in the stella-libretro core that was causing this issue. I’ve submitted a pull request to the libretro/stella-libretro repository, but I’m not sure who maintains that (and the last time there was a commit was 2 months ago), so it might not be merged all that soon.

In the meantime, users can get the version with the bugfix from my fork at https://github.com/mdraves91/stella-libretro.

Cheers!

@mdraves91 That’s awesome, man :smiley: The patch looks pretty solid to me.

It’s under the libretro umbrella, so Squarepusher or Toad King (among others) should be able to pull it in. Thanks for taking the time to get that going!
