Floppy disks : unable to swap outside of MD mode except, when run-ahead enabled (or otherwise, in a temporary way, after altering an unrelated setting)

[bidinou]

Hi ! I am encountering the following floppy disks related issue. Configuration : KDE Neon (Ubuntu 20.04 based) + snap packages of Retroarch (up to date).

I cannot swap disks in non Multidisk mode, even if they are in a M3U playlist and even if I eject and select the new disk properly

HOWEVER I did manage to get some MultiDisk games work in MD mode (for example Athanor 2, as this game supports several floppy drivers)

I guess I'm definitely doing something wrong :-) Cheers & thank you so much !!

OK, I'm editing this issue after making quite a few tests. I've figured out something new :

Swapping floppy disks does NOT work UNLESS changing the "whdload support" setting and closing the current content, restarting the core (not restarting RA) !!

I can either change from "none" to "files" or from "files" to "none". Close content. Load an ADF, and, tada, I can swap disks !

If I don't do that, after selecting a new disk, it is not detected.

I have to do this once each time I start RetroArch. Then floppy disks swapping works until I quit RA.

(Edit : I also edited my initial post as I had made a mistake regarding some incompatible disks ; there was another problem, it was my fault)

That makes absolutely no sense, since the value of that core option is only investigated when booting hard drive images, not floppies.

Debug level log output would shine a light.

I can append/insert floppies just fine regardless if booted with floppies or hard drives.

Yep, it indeed makes no sense at all -- but it's 100% reproducible here :) I'll send you a debug log as soon as possible. Thank you :)

I also made a post on the forum, to see if other people encounter the same problem as me :) I hope you don't mind ! https://forums.libretro.com/t/unable-to-swap-disks-non-md-unless-altering-an-unrelated-setting/35718

AAAH !!! Figured out ! Yet another bug triggered when the global "run-ahead" setting is enabled ! Disk swapping works 100% when it's disabled (without modifying unrelated settings ;)

Here is the debug log in which I start PUAE with SOS1.adf (Shadow of Sergoth, new RPG :) and try to swap with SOS2.adf. It's not inserted / detected. https://easyupload.io/yhhjat

I'll close this one too since I think frontend related run-ahead issues should be fixed in the frontend.
