SFW got corrupt, that's easy to see, wondering why they suspected adaptives...
Franc probably copied it from the inactive container.

You can use F3RomExplorer to analyse the ROM:

The SFW segment in the active container (BFWContainer1) had a bad CRC. This turned out to be an error in a single bit. There was a good copy of the SFW segment in the inactive container, BFWContainer0. I compared the two copies and used the good copy to repair the bad.

Good copy of SFW
