Topic: Apparent bug: Bullet (Sega, arcade)

[PrincessMonaco]

Unless I'm missing something embarrassingly obvious, there's no way to set up any firing controls in this obscure twin-stick shooter reminiscent of Total Carnage.

I agree with you that it's misnamed in "Map Game Inputs". But you can map fire buttons this way:

P1 Up 2    -> FIRE UP
P1 Down 2  -> FIRE DOWN
P1 Left 2  -> FIRE LEFT
P1 Right 2 -> FIRE RIGHT

You can press two fire buttons at same time for diagonals. Arcade cabinet has an additional lever to fire.

It seems to work as expected on my side.

In what way? I get nothing from the second stick no matter what configurations I try. What should they be?

[fprietog]

This is my Input Map. The keys 'S' 'X' 'Z' and 'C' are the directional fire (acts like a second lever). Map yours in a similar way.

This is how I have mine, in the pic below

Notes:
I use Joy2Key to map both my d-pad and left thumbstick to: 7698
This way I can switch between the d-pad and left thumbstick when I want to..
For example: in a shoot-em-up, I'd use the thumbstick mostly, but on a really
intricate scene, I'll switch to d-pad

Though, for Bullet - both thumbsticks are awesome.  good luck!

I'm using a double arcade joystick so that's no use to me.

Hmmm, i used the libretro core where the right stick was mapped to my controller's right stick out-of-the-box, meaning emulation-wise it works and it's a setup issue on your side. I'm not entirely sure what your problem is ? Maybe if you posted a screenshot of your input config we might figure out something ?

[PrincessMonaco]

It defaults to the first two pics - both sticks set to "Up 1", "Down 1" etc. There's no option for "Up 2" etc. The only alternatives are "Right Stick" and "Fake Left Stick", neither of which do anything if you set Port 2 to them.

[barbudreadmon]

Oh, you are using retroarch.
The 2 sticks belong to the same player.
You'll need a more recent version of retroarch with the "mapped port" setting if you want to use 2 different controllers for the same player, it used to be impossible with ultra old versions like yours.

edit: Specifically you'll need to set it to 1 (= 1st player) for "port 2 controls" (= your 2nd controller), then remap things so that the stick of your second controller controls the right analog in that same "port 2 controls". For any other question i'd recommend asking the libretro community since how retroarch handles remapping has nothing to do with us.

[PrincessMonaco]

Ah, thanks. I'll just stick with MAME 2016, in that case - I'm not updating Retroarch, my blood runs cold thinking about the utter chaos that could cause.

Does Robotron 2048 work fine for you?  I'll try to use the same key namings that is uses and see if that helps

[dink]

barbudreadmon, any ideas how we should handle this for lr?
Having 3 players kinda complicates things, doing it like Splat or Robotron 2084 (pre90s/d_williams.cpp) seemed like a good idea at first, but the p1/p3, p2/p4 stuff on the right side of the structure doesn't translate well to 3 players.  What do you think?

Please do nothing, at best you'll just end up making things unplayable for everybody using one single controller to play those games, meaning 99% of the player base.
Using 2 controllers to play one single player was a long term retroarch missing feature, it was finally implemented around 5 years ago, but there is nothing we can do for users who refuse to update it.
There is enough problems with retroarch's current lack of flexibility regarding mapping without having to also deal with even further limitations from older versions.
Ofc, this does affect every twin-stick games including robotron.

edit: I suppose this is on linux so i guess using the sdl2 builds would be my recommendation here ? I think they have more flexibility regarding this.

No, Robotron is the same, no firing.
