Retroarch crashes when loading roms after deleting previous core

RetroArch Windows devices
#1

I downloaded a bsnes core to run a game (Chrono Trigger) and since it was laggy on my older computer, I deleted it from the cores folder and downloaded the SNES9x core instead.

Now when I try to load this specific rom from my database, retroarch immediately crashes. Other roms that I did not open with the bsnes core open normally.

I ran the logging debugger and got this:

As far as I can tell, for some reason Retroarch is still trying to load the bsnes core that I deleted even though I’ve manually loaded the SNES9x core before even opening the rom. Does anyone know how I can fix this? It must be saving the last core that was used to open the rom somewhere and defaulting to that instead of the core I’ve selected for some reason, but I cannot for the life of me find anything like that in my files.

Delete your playlist.

Of course, right after I post this thread I finally track it down. in the SNES lpl file in the playlist folders this was hanging out:

Nintendo - Super Nintendo Entertainment System.lplY:\Games\Roms\Super Nintendo\Chrono Trigger (U) [!].zip#Chrono Trigger (U) [!].smc
Chrono Trigger (USA)
[B]C:\My Games\Retroarch\cores\bsnes_mercury_accuracy_libretro.dll
bsnes-mercury Accuracy[/B]
2D206BF7|crc

I pasted in DETECT for both lines and it allowed me to load the snes9x this run.

I think this is a bug? I’ve got the latest version and Retroarch definitely shouldn’t be trying to load a core that’s been deleted, since from what I’ve read online the way to remove a core is to just delete it from the cores folder.

While that also would have worked, I don’t think I should have to rescan my entire library every time I decide to use a different core for a system.

It’s not a bug. It saves the core used so you don’t have to keep selecting it every time you select a game from your playlist. If you don’t like that then set your playlist file to read-only.

#5

Then why isn’t there a way to select a new core for a game after you delete an old one? Even if I hadn’t deleted the previous core, I would assume that if I manually loaded a core first Retroarch should use that core instead of the first core I ever loaded that game with.

#6

Playlists don’t know which core is loaded. You can associate a playlist with a specific core in settings > playlist
