See readme for usage

For use with: https://github.com/kounch/knloader

Written for the mac, though I'm sure it can be adjusted to work on linux and WSL.

Make sure to change SD_CARD and GAMES to the root of your SD Card and the games/rom folder on the card - this last variable GAMES is needed in the knloader.bdt database.

Then run as:

sh knloader-db-maker.sh > knloader.bdt

Copy the file across to your SD card into the same location as the knloader.bas file, then follow the directions at https://github.com/kounch/knloader

Notes

• The types are hardcoded in the script as: TAP=1, TZX=10, etc - see the database format for the types that suit you.

knloader-db-maker.sh

set -e
# set -x

# change these vars to suit your own locations
SD_CARD=/Volumes/NEXT
GAMES=/ROMS

function upper() {
  echo $1 | tr "[a-z]" "[A-Z]"
}

# modes hard coded - adjust to your needs:
# https://github.com/kounch/knloader/blob/master/docs/Manual_en.adoc#database-file-format
function modes() {
  ext=$(echo $1 | tr "[a-z]" "[A-Z]") # to uppercase

  if [ "$ext" = "3DOS" ]; then
    echo "0"
    return 0
  fi
  if [ "$ext" = "TAP" ]; then
    echo "1"
    return 0
  fi
  if [ "$ext" = "TZX" ]; then
    echo "10"
    return 0
  fi
  if [ "$ext" = "NEX" ]; then
    echo "15"
    return 0
  fi

  # default to SNA, etc
  echo "16"
}

function format() {
  full=$@
  filename=$(basename -- "$full")

  filePath="${full#$SD_CARD$GAMES/}"

  if [ "$filePath" = "$filename" ] ; then
    filePath=""
  fi

  extension="${filename##*.}"
  base="${filename%%.*}"
  mode=$(modes $extension)

  echo "$base,$mode,$filePath,$filename"
}

echo $GAMES

find $SD_CARD$GAMES -type f \( -iname '*.tap' -or -iname '*.tzx' -or -iname '*.sna' -or -iname '*.z80' -or -iname '*.nex' \) | grep -v '/._' |  sort -i | while read line; do
