@Bushmeister Frogger and Pac-Man (and many others) only had one set of controls; there was no need to install a second set of hardware, since the players take turns anyway. As far as the game is concerned, there aren't any "player 2" inputs except for the second coin slot and the 2-player start button (select and start on the second controller.)

You could remap this so that both sides control "player 1" (except for start button of course) and you can even make it only for these games so that 2p simultaneous still works on other titles -- the only catch is, they will both be always active so you have to trust the other person not to interfere when it's your turn.

Seems to be this game ?
You may try starting the game with mame2003-plus (mame2003 might also work) and use the Mame mapping menu (hit Tab on an attached keyboard) for the game. The up/down movements of the gun are mapped to a couple of Paddle inputs, which you can assign to the 2nd joystick of the player.

@mitu nevermind, I figured out the problem. You have to go to "Exhibition Game" to play two players..LOL :).. Thanks for your help.

Thanks!

I never played fighting games much - always liked the spaceship games - so that explains why I didn't even think of that.

@edmaul69 That could well be awesome:) I won't say no yet, but I may well have a go myself (eep) I didn't think I was using a hackfile, but i need to compare my two systems to see if one had been loaded via the Donkey Kong rom I put on there.
Not going to burn any bridges, your offer is genuinely nice:) I'll see what I can tonight. Thank you!

I tried device_joystick raw first and had no luck with either controller, but sdl worked so i stuck with that. I will take another look at it. Thanks for the reply!

no worries i figured the dongles might be 'fighting' for priority as i beleave the dongles set the controller position before then sending it to the system itself therfore 2 dongles would mean 2 controllers trying to control P1 probly a more descriptive reason for this somewhere but i guess thats what is basicly happening there glad your sorted

@BuZz Switched to UAE4ARM and now the gamepads work without any problems! Thank you! Spent some time trying to figure this out and messing with xboxdrv... :-) :-). Now it just works.

@mediamogul said in C64 VICE Is it possible to use two joysticks?:

@gold64

Select 'Joystick' for both. This doesn't actually select a specific connected joystick, but rather tells the emulator to use joystick mappings. The joystick mappings can be configured to your connected joysticks near the bottom of the same menu.

Ah, I understand it now, thanks @mediamogul . So that option tells VICE what type of controller to use in each port, vs. actually selecting a specific controller to use. I was now able to get both DS4's working, and play a game with two players, after mapping each controller using the other setting. I then saved the config files and copied them to my PC in case I mess it up again.

Yes, I wonder if VICE isn't currently broken in some way with regards to how it saves (or possibly loads) its configuration files, but I wasn't able to reliably reproduce the problems I was having when I first setup a single DS4. Just kept trying until I got it to work.

Thanks for the quick replies everyone.

Um, this issue is solved I guess, not sure how I mark this topic as solved (sorry, it's my first thread)? Thanks.

@meleu Yep, changed it, but it still wants to use controller #1 to control Luigi

Hi

I am no expert. But mame is emulating the actual arcade machine. So in arcade games such as galaga there was only one joystick so not sure there would be a way for it to emulate a 2nd joystick

There was as you noticed 2 start buttons though.

I have not tried this but what u could do is go into the mame configure screen. Hit tab with a keyboard plugged in. tell it to use a button on your 1st controller for 2 player start.
