Multitap for psx broke in latest update

robmcc83

Yeah I would say I'm comfortable with command line, used it many of times on other projects :)
Thanks

In my case, I’d create a new folder and checkout the lr-pcsx-rearmed code to that folder.

cd ~/
mkdir pcsx
cd pcsx
git clone https://github.com/libretro/pcsx_rearmed.git
cmake .
./configure --platform=libretro --disable-neon

The cmake command might not be needed, it’s been a while.

Then, it’s just a matter of checking out an older commit from the project, which you can see the hgashes from in the commit history:

https://github.com/libretro/pcsx_rearmed/commits/master

It’s the 7-character hash in each commit line.

28ea3e2 is the latest one. You may start with 40c380a and see if it works.

git checkout 40c380a

and then build it

make clean
make

and then copy it to the right folder at

sudo cp libretro.so /opt/retropie/libretrocores/lr-pcsx-rearmed/

and run it. See if it works. If not, try another commit (likely an older one).

You can always restore it to the original one by updating via the RetroPie-Setup script.

In fact, if you want to go about it and make it easier to fix for the folks over at the actual project repository, you may consider helping bisect it to the right commit. If that’s something you’d be interested in investigating, let me know and I can share instructions.

There’s the odd chance that it’s not an emulator issue but rather a libretro/RetroArch issue. That I’d not be as comfortable with, but I’m sure others can help track it down.

Let me know if it helps, and best of luck. If something doesn’t quite work, just let me know, as I didn’t test this, just wrote it from memory and checking the source for the install script at:

https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/libretrocores/lr-pcsx-rearmed.sh

Happy new year!

Hi and happy new year to you too :)
only just had chance to look at this as I've had a sore head due to, to much beer last night lol.
I'll have a play around tomorrow and let you know the outcome.
On my spare 8gb sd card I'm going to start with a fresh image, check everything works fine.
Then I'm going to update via retropie script (That's when multitap stops working)
I'll then work my way through compiling the core as you suggest, if one version work I'll work my way through them until I find which version it has stopped working in.
Many thanks
Rob

@robmcc83 If you really want to test it, I'd also do the following test

install from the 4.4 image
update from binary
(after the update) set up Multitap options in pcsx_rearmed.

Also, could you post your /opt/retropie/configs/retroarch-core-options.cfg file ?

Hi all,
So just tried this and I have 2 errors
The first is the cmake command it tells me the source directory doesn't contain any cmakelists.txt

So as you said it might not be needed I went onto the next command and that gives me error bash ./configure : no such directory.

Many thanks

Ignore that last reply.
I had to change directory to /pcsx/pcsx_rearmed as it seems to of created another directory during the process.
Seems to be going ahead now :)

Right so doing the above seems to have broke alot within pcsx.
I'm not quite sure it has worked but it has done something.
It says it pcsx r22 within retroarch but doing the above has added shaders that were not on there before and it has broke graphics as I just have multi coloured line on everything 3d but 2d stuff appears to be showing correctly.
Thanks

@mitu
How do I post the /opt/retropie/configs/retroarch-core-options.cfg
So it looks neat like other people do on here. Thanks

To post a code formatted block, surround the lines quoted in backticks (```) on separate lines at the beginning and end.

Ok so I think I may have solved my issue which maybe a silly error on my behalf or something has still changed in later versions of retropie because I don't think I've ever had to change controller types.
But even though I've solved one problem it appears to have created an new problem.
Firstly I'll start with saying with default settings I usually have just turned on game specific options, started game, enabled multitap 1 in retroarch and all has worked. But it hasn't this time that's why I've had problems.
But what I have just done is changed player 1-4 controller type from default to standard and micro machines v3 has just worked with all 4 controllers.
I've then launched hogs of war and that has worked making sure controller type is analog.

So firstly i would like to know why player 1 and 2 controller would work with them all being on default but controllers 3 and 4 wouldn't.

Now onto my new problem.
When setting multitap and controller type in options and saving game specific options, a yellow notification pops up saying core options saved.
And it appears to be saving it across all games as a core option rather the game specific option.
I have double checked and game specific options are set to true.

Thank you all for your help I'm almost there :)
