Puae2021 core crashes when loading save states

Libretro Cores
#1

Hi everyone, When using the latest puae2021 core (2022-12-13 22:59) (via retroarch via launchbox) I save a state (F2), reload it (F4) and the emulation either crashes to desktop or shows a green flickering screen in the still running emulation. I can still successfully load save states from previous versions of puae2021, only new states crash.

Amiga emulation has a high emotional value for me, so I’m horrified :wink: As you can see, this s my Turrican save #140, which objectively is cheating :grimacing: No, really, please please fix this (or tell me what to do differently)

#2

Thanks for notifying. It was a botched and rather needless audio backport operation on my part. Fix pushed. All new saved states were affected, so just save again from a working state.

Hi sonninnos, That was quick, thank you very much! I used the auto updater in RA and when this didn’t work, I got the core here: https://buildbot.libretro.com/nightly/windows/x86_64/latest/ Unfortunately, the symptoms are still the same.

Did I fetch the right core? I tested with version 2.6.1.3a75159 but don’t know which version I used before, sorry.

#4

The buildbot hasn’t updated the core yet. That is the old version hash.

Also hot tip for the future: Wrap the output with three backticks when posting logs.

Like so.
And so on.

Hello everyone, I have a similar probleme with PUAE 4.9.1 d9a8dfb, Dec 2 2022 22:55:01 on linux retroarch 1.14.0 (Git 932b4ad3db). Amiga games run perfectly, but when I load a save state, the screen displays a mess. Program seems still working, but nothing is readable on the screen. Retroarch still works during the problem.

States are working fine here even with that same game, so maybe it is game specific or a random encounter, so try with version 3.4 of Flashback slave and other games.

And PLEASE wrap log output with three backticks because that is completely unreasonable reading…

Sorry for the poor log. I tried with all my amiga games and there is the same problem for all. it was working well in a recent past, and I dont remember after what update it went wrong (arkos update for instance) I reset all core options: nothing

#11

If the states are taken with the same version, I have no idea, since they are working here…

#12

I will use retroarch32 and uae4ARM, not the same experience but it is working. Thanks for your help
