Need help badly regarding PS4 controller

Known2Own

@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.

@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.

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.

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

Error messages received: "core does not support save state"
Log found in /dev/shm/runcommand.log (if relevant):
Guide used: (Mention if you followed a guide): pretty much every single thing found on the net couldn't help my case.
File: (File with issue - with FULL path)
Emulator: (Name of emulator - if applicable):
Attachment of config files: (PLEASE USE PASTEBIN.COM FOR LARGE LOGS)
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.

ok cool appreciate your help.
