Mame2010 appears to have savestate = false in their config, so maybe the 'cannot save' message is normal. Other MAME cores do have 'savestate = true' though (MAME2003, MAME2003+, MAME).

Ah great, that put me down the right path. I did have the .info, and my retroarch.cfg for NES was pretty bare bones, but looking for other .cfg files I found this:
Turns out I had a really old config file under ~/.config/retroarch/config/FCEUmm/FCEUmm.cfg

Renaming that file so it wasn't loaded fixed the issue - now I can use save states in nes games again :)

Thanks!

Please add some info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first and use the correct category for your posts (I moved your post to the support category, where it belongs).

The hotkeys are automatically added when you configure your controller in EmulationStation, can you post the controller profile generated for your controller, located in /opt/retropie/configs/retroarch-joypads ? There should be a .cfg file named after your controller, which contain the configuration of the controller.

@windg Not sure what I did. But every game I loaded had a notification that said "configuration override loaded" when I disabled that in the RetroArch options I can now save again!

Thanks for helping!

@sleve_mcdichael now when I try and connect to my Pi from my PC using ssh pi@retropie.local (which you helpfully advised in another post) it just opens a black box for 3 seconds which then disappears before I can do anything. My PC and Pi are on the same network.

My pi 4 isn't overclocked - what settings would you suggest I use for that please?

I don't have any recommendation, as i said i don't own a pi4. I'm just thinking that garbled sound can be the result of performance issues, and gpgx appears to be surprisingly demanding. So i'm wondering if an overclock could improve things.

should they be enabled?

Probably not, they are features that will lessen performances.

On a sidenote, savestates with the nuked setting appear to be broken to me : i just tried loading my savestates from yesterday and the core crashed, after some more tests it appears the core can't load savestates from another session on my setup (it works just fine if i set it to MAME). That might be related to your issue. Maybe report this to the author, and/or change setting/emulator.

There are no performance issues whatsoever playing a game with nuked sound in the initial session

Your sidenote issue IS the issue that I have been concerned with the whole time. Thank you for corroborating that. I think this emulator is the only one with nuked fm sound.

@sleve_mcdichael thank you i didnt know that

@mitu So sorry for the delay...busy week and didn't have much time to play. Just tried my ps3 controller and yep, you're right it's simply the controller itself.

Thanks everyone.

@mitu That did it! The file was in autoconfig called Arduino LLC Arduino Leonardo.cfg

Now when I push Select and Trigger nothing happens. Phew! :)

@YFZdude said in Save States:

The SELECT button is it's own button. The HOTKEY can be a different button. You may not have any games that use SELECT. What matters is that you have a mapped HOTKEY button. To save states it should be HOTKEY + R1.

Yeah, the hotkey +R1 is working fine now. Silly me. I understand now. Thanks for your explanation though. Now for some retro gaming fun!

Finally i get rid of save/load state functionality. i change the following:

1- This is for the gamepad.

From/opt/retropie/configs/all/retroarch-joypads
i remove the lines for save/load states.

2- This is for the keybord.

From /opt/retropie/configs/all/retroarch.cfg
i change the lines from

# input_save_state = f2
# input_load_state = f4
to
input_save_state = f22
input_load_state = f44

3- This is to hide save/load state option, in rgui quick menu.

i add to the/opt/retropie/configs/all/retroarch.cfg

the line quick_menu_show_save_load_state = "false"

Got it solved.
I outsourced the config-files to "/home/AMIBERRY Inputs".
Now everything works, i learned that retroarch seems to browse also the subfolders within "opt/retropie/configs/all/autoconfig/" ;)

@mitu said in Suddenly my save states dosent work.:

Save states are not always portable between emulators, so a save state from lr-gambatte might not worth with lr-mgba . Is the emulator version the same as the one you used for the save states ? Sometimes an upgrade of the emulator makes it incompatible with previous versions' save states.

Hmm maybe it's because of an emulator upgrade. I played the game for a couple of month before I did the backup. And after I think I did an update. Thanks, I did not know it might cause a problem. At least the "normal" save file works.

@cyperghost said in Suddenly my save states dosent work.:

@lesk ... and it's more likely that a battery savestate gamename.srm will work more reliable and may be portable to other emulators ;)

Thanks, yeah the normal game save seems to work just fine ^^

@mitu Thx for this. would you happen to know if I define a location of a folder that does not exist, will it create said folder for me or return an error instead?
