SNES Multitap Issue

Hyruleslink

@akafox it's a weird issue for sure. Oh well. Thanks for trying, I appreciate you checking for me.

I've got the same issue explained by Hyruleslink: when the mulitap is enabled in lr-snes9x2010, player 2 controls players 2-3-4-5, BUT I've only got this issue with specific multitap games.

So far I've noticed that these game are not working properly with the multitap:
Otoboke Ninja Colosseum
Super Fire Pro Wrestling X Premium
Firestriker

But these are all working fine:
NHL '94
Super Tetris 3
Super Bomberman 1-5
The Peace Keepers

In case this may be relevant, I'm using 2 Street Fighter IV X-Box Pad and 1 Street Fighter IV PS3 Pad.

@pixeltao If I find a solution, I'll post it here. Still trying to figure it out. If you could, check your RetroArch options for a game that does work and for one that does not work. See if there is any variation in the settings. That may provide a clue to what's going on.

@hyruleslink Cool thanks! I'll do the same if I figure it out. I've compared the config files (.rmp files) for Firestriker and Super Bomberman and they're exactly the same. It's really weird. In your case, does this happen with every multitap games?

I don't suppose there've been any new developments with this, have there? I'm trying to get 3-4 player play working with Secret of Mana and Super Bomberman 2, and I'm having the same issue with controller 2 acting as controllers 2, 3, and 4.

@temporalpirate Unfortunately no new developments on my end. I haven't tinkered with this issue in quite some time, but when I do look at it again, I will be sure to update this thread if I find a solution.

@hyruleslink Okay so I understand your problem. I had the same issue (at least with firestarter) I installed the lr-snes9x core (the one without the year) and firestarter works like it should. When I have more time i will test the others you mentioned you had problems with if you have other problems.

I think there seems to be a bug in retro arch in that it seems to be initialising the multitap after the ROM has booted.

This can be seen in "Looney Tunes B-Ball (USA)". Retroarch is still posting "Gamepad found" messages after the ROM has begun it's intro, only 2 players are available.

If you then "select + x" and "restart" after all the retroarch post messages and gamepads initialising is done, the multitap is then detected and 4 player games are available.

Not all games are affected but there should be an option to delay the ROM start for a few secs while Retroarch is initialising joypads.

Cheers,

I still have this exact problem. Setting player 2 to multitap, I try to play New Super Mario World (which supports 4 players), and the first player works fine, but the second controller controls the other 3 players at the same time. The third controller does nothing (although is detected by the system and I can use it to browse the menus).

Any ideas?

EDIT: Someone pointed out that the solution was to use the emulator lr-snes9x for that specific game, and it works just fine. (source: https://retropie.org.uk/forum/topic/24109/new-super-mario-land-snes-homebrew/24)

@xwons Thanks for sharing your solution.

@xwons I just came across this thread on google, registered to this forum just to confirm xwon's solution fixed this problem for me. No more troublesome multitap snes games! Thank you for taking the time to respond to this thread with the answer.
