Fixing Game Freeze in FF7 Kalm Flashback on PCSXR for Mac

I ran into a glitch playing Final Fantasy VII on my Mac Playstation emulator. I found a fix!

Cause: The instructions for PCSXR tell us to load a pack of BIOS into the BIOS folder. This is wrong. There should only be one BIOS in there.


  1. Create a spare folder on your desktop.
  2. Go to Folder  ~/Library/Application Support/PCSXR/Bios
  3. Drag all the BIOS out of that folder into the spare folder on your desktop.
  4. Then select and drag SCPH1001.BIN back into the PCSXR/BIOS folder.

Before fix: FF7 freezes at the end of Sephiroth’s battle with the dragon during the flashback to Cloud’s past, right after this:

sephiroth fighting the dragon in nibelheim

After fix: there’s a looong black screen after the battle, then the game pops back to the inn in Kalm:

Cloud: Sephiroth's strength is unreal. He is far stronger in reality than any story you might have heard about him.

My other, less-desirable solution was to pick up a saved game file from here shortly after the glitch, but then I’d lose my limits and overleveled party.

I still have a working PS2 and a back-compatible PS3 that plays the game discs. If all else failed, I was just going to go back to the PS3. But emulating on my Mac allows for screencaps.

      I can’t remember how long the pause was… probably a good 5-10 seconds. Sorry, if the above solution doesn’t work, I don’t know what else to try. 🙁

    I did it, but nothing’s working. I still get the freeze even after keeping only the SCPH1001.BIN. I’m going to download a save-state after the flashback, but I’d really appreciate it if I could get a fix ;.; Thanks in advance!

        Just found a solution! I don’t know why, but after performing the above fix…

        Instead of relaunching my game from a frozen state, I relaunched from a saved game. From there I was able to play through.

    Hey guys, so the first time I tried it, it didn’t work. Did the exact same thing again and it did. So, give it a few tries before giving up! 🙂
