Hey guys, I'm playing some special PS1 games that require some special BIOS to run, so I wrote an event script for that. When the game is running, copying a special BIOS to replace a normal BIOS still has no effect. Did I overlook something?

# /Volumes/share/userscripts/runpsxgame[rungame](sync).sh
param=""
destination="/recalbox/share/bios/scph7001.bin"
original_destination="/recalbox/share/bios/psx/scph7001.bin"
while [[ $# -gt 0 ]]; do
    case $1 in
        -param)
            if [[ -n $2 ]]; then
                param="$2"
                shift 2
            else
                exit 1
            fi
            ;;
        *)
            shift
            ;;
    esac
done

if [[ "$param" == *"roms/psx"* ]]; then
    game_name="${param#*roms/psx/}"
    game_name="${game_name%.*}"
    bios_file="${param%/*}/$game_name.bios"

    if [[ -f "$bios_file" ]]; then
        cp "$bios_file" "$destination"
    else
        cp "$original_destination" "$destination"
    fi
fi
