PSA: Backup Your Retroarch Cores Before Updating

[Lordmonkus]

I just did an update of my Retroarch cores recently and noticed 2 significant problems. Problem #1 was my Saturn emulation went to complete shit in terms of performance, I went from a solid 60 fps down to 50. Problem #2 was the Playstation game Gaia Seed: Project Seed Trap stopped working.

Luckily I still had an old Retroarch install folder with older cores so I just copied those 2 cores over and both issues fixed instantly.

Wow! I wish I had thought of this before. Now I just tried Daytona USA with the latest Mednafen Saturn core and it's noticeably slower and stuttering. Don't have the older cores any longer though. Oops!

Here are the older cores i'm using, not sure exactly how old and what versions they are but it's what I got.

mednafen_saturn_libretro.dll

mednafen_psx_libretro.dll

I wonder what the issue is? I guess it'll be fixed in a nightly build soon.

Something similar happened a while back with the Wonderswan core. A member posted a few games no longer worked. Thankfully I had not updated and was able to test the prior core still worked. So now before I update any cores I will back up the core folder.
