Need help badly regarding PS4 controller

Known2Own

Hi,

This is my first post. I hope im not breaking any rules or something.

I got my (3 B+ raspberry pi) retropie set up, did my control config. and no matter how many videos or reddit posts I've read nothing has helped. It simply won't pick up the start/select buttons so that I can save my games. It picks the start/select buttons up just fine in the retropie menu but never in a game. I tried using F12 to save state but that doesn't work either and there is also no load state option in the in-game menu (this game) options. The controller is connected via USB cable. I re-imaged and re-installed everything, updated/upgraded everything. Still nothing.

I was using mame4all games (turtles in time) to test this out. I also tried the simpsons arcade game rom. These are the only two roms I have that I got to work so far.

I'm at my rope's end and don't even know where else to go to read something I haven't already read or watched on youtube.

I'd really appreciate any kind of help. Let me know if you need any more information that I haven't supplied, not sure what else to include.

Update: on the arcade emulator, when I try to save with the Select+Rshoulder it says "core does not support save state" - what does this mean and how do I fix this issue?

mame4all is not a RetroArch emulator, so save/load via the Hotkey (Select) will not work.
Use a Libretro core emulator - lr-mame2003, lr-fbneo - for arcade games and the hotkeys for save/load will work automatically. Make sure you read and understand how Arcade games work - https://retropie.org.uk/docs/Arcade/ - so you will not have problems with ROMs not working.

@mitu I got the same outcome using lr-mame2003 and the game (in this case, battletoads) won't even boot at all with lr-fbneo.

mitu

If you're using lr-mame2003, then the Hotkey shortcuts should work - what button did you configure as Hotkey when configuring the gamepad in Emulationstation ?
As for the ROM not working with lr-fbneo - see my previous post.

Known2Own

@mitu and now its stuck on lr-fbneo and won't let me change it for some reason under which method to use for this rom. I skipped the hotkey when configuring my ps4 controller because that's what a bunch of forums and videos said to do.

@Known2Own said in Need help badly regarding PS4 controller:

When you skip the hotkey, the configuration dialog will ask you if you want to use Select as the hotkey - did you choose this option ?

Known2Own

@mitu yes, i selected yes.

mitu

OK, so your Hotkey should be set. Are you able to access the RetroArch RGUI by using Select + X ?

Known2Own

@mitu I don't think so. Do I press select and X at the retropie menu or in-game?

mitu

The shortcuts are working in a game, when you start it with a lr- emulator (lr-mame2003, lr-fbneo, etc).

Known2Own

yeah still doesn't work even in-game.

mitu

Please add more info about your system and how it's set up - https://retropie.org.uk/forum/topic/3/read-this-first.

How to replicate the problem: try booting turtles in time smulator via mame4all and saving. it won't save no matter what. OR you can try booting battletoards via arcade and save to get the error msg.

mitu

@Known2Own I think the message it quite clear:

Error messages received: "core does not support save state"

Not all drivers (i.e. games) have save state support in the emulator version you're trying.
For the record, saving/loading works fine with lr-fbneo.

Known2Own

@mitu so if the rom doesn't boot using fb-neo then there is no save function?

mitu

@Known2Own I'm saying that with the proper ROM, save states work in lr-fbneo for the tmnt2 arcade ROM.

Known2Own

ok cool appreciate your help.
