Default behaviour for BRAM should be 'locked' at startup; this is currently correct for CDROM games, but not for HuCard games.

This means that memory at physical address $1EE000 should be all $FF values (as seen by the Physical Memory debug screen), but the BRAM memory editor screen should show the BRAM properly.
