Multitap support? #9

Open Holzhaus opened 9 years ago

Holzhaus commented 9 years ago

Multitap seems currently not supported: I'm unable to play Bomberman with more than 2 players, although It does work with the snes9x-next core. Is this a planned feature?

I think 9bfbd02b2bfba3bb2362d4cdf566a632d14186cd is supposed to fix this, but no clue how it is supposed to work. This is an annoying issue since snes9x/snes9x-next libretro cores have multiple issues on rpi2 right now (segfaults with -O3, freezes on a few multitap games, ...)

Just to correct what @barbudreadmon wrote above: The linked commit was not supposed to fix problems with multitap, and it didn't.

It would be nice to get some information about what could be expected from the current multitap implementation: In the code, it seems like it would be supported, though I couldn't get it to work.

In order to also allow proper mapping of controllers, I backported the controls code from the snes9x master into snes9x 2002. I was able to get it as far as correctly telling games when a multitap input device was connected. However, games don't seem to recognise input from the controllers that are attached to the multitap.

I have uploaded my attempts to GitHub. Do you guys probably have any ideas what I might have missed?

(I'm aware that you probably wouldn't like to see c++ introduced into the code base, but I just noticed snes9x 2010 has a c version of that code (controls.c) that should be relatively easy to use instead, once general functionality has been proven.)

Any news on this?
