## Irkenlabs JAMMA Expander

From <https://github.com/misteraddons/mistercade_mappings>

1. Add the following section to the end of to the file downloader.ini that
   should be found in the root of the SD

    ```ini
    [misteraddons/mistercade_mappings]
    db_url = https://raw.githubusercontent.com/misteraddons/mistercade_mappings/db/db.json.zip
    ```

2. Run update_all.sh
3. Via SSH, run the following to rename the MiSTerCade
   input mapping for the JAMMA Expander VID/PID:

    ```sh
    cd /media/fat/config/inputs
    shopt -s nocaseglob
    for file in *16d0_10be_v3.map ; do cp $file ${file//16d0_10be/8282_3201} ; done
    shopt -u caseglob
    ```

3. MiSTer main menu > Define joystick buttons
4. Switch JAMMA Expander from Keyboard to gamepad input
5. Press left on Joystick
6. Use JAMMA Expander to input keypress for Space, twice (skipping Joystick detection)
5. Press inputs in this order
    1. Joystick Right
    2. Joystick Left
    3. Joystick Down
    4. Joystick Up
    5. Button 1 (A)
    6. Button 2 (B)
    7. Button 3 (X)
    8. Button 4 (Y)
    9. Button 5 (L)
    10. Button 6 (R)
    11. Coin (Select)
    12. Start (Start)
6. Use JAMMA Expander to input keypresses for Space to skip all other inputs

## Useful Shell (bash/zsh) One-liners

### Hyundai i30 USB flash drive format - needs to be FAT32 and small sector size
`mkfs.fat -S 512 /dev/sda1`

### Directly image a block device from a compressed image
`gunzip -c < "image_name_here.img.gz" | sudo dd of=/dev/mmcblk0 bs=10M conv=fsync status=progress`

### Delete duplicate files
`fdupes -rtdN . `

### Zip all sub directories individually
`for i in */; do zip -r "${i%/}.zip" "$i"; done`

### Zip all files individually
`for i in *.*; do zip -r "${i%.*}.zip" "$i"; done`

### Rename photos using EXIF metadata
`exiftool '-filename<CreateDate' -d ~/Pictures/photos/%Y/%Y-%m/%Y%m%d-%H%M%S%%-c.%%le -r -ext cr2 -ext dng -ext jpg -ext JPG -ext Jpg .`

### Remove empty folders
`find . -type d -empty -delete`

### Move all files in subdirectories to current directory
`find . -type f -exec mv {} . \;`

### Convert all WAV files in subdirectories to FLAC. Needs bash shell installed
`find . -type f -name '*.wav' -exec bash -c 'ffmpeg -y -i "$1" -compression_level 12 "${1%.wav}".flac' - '{}' \;`

### Convert VOBs to MKV losslessly, retaining audio and subtitle streams
`ffmpeg -fflags +genpts -analyzeduration 100M -probesize 100M -i "concat:$(echo VTS_03*.VOB|tr \  \|)" -y -dn -map 0:v -map -0:a -map 0:s -c copy -f dvd VTS_03.mkv`

### Rename music in current (subfolders) using ID3 tags
```sh
exiftool -r -P -ext mp3 -ext m4a \
 '-filename<~/Music/${Artist;} (${Year;DateFmt("%Y")}) ${Album;}/${track;$_=sprintf("%02d",$_)} ${Artist;} - ${Title;}.%e' \
 '-filename<~/Music/${Artist;} (${Year;DateFmt("%Y")}) ${Album;}/${PartOfSet;}${track;$_=sprintf("%02d",$_)} ${Artist;} - ${Title;}.%e' \
 '-filename<~/Music/${Band;} (${Year;DateFmt("%Y")}) ${Album;}/${track;$_=sprintf("%02d",$_)} ${Artist;} - ${Title;}.%e' \
 '-filename<~/Music/${Band;} (${Year;DateFmt("%Y")}) ${Album;}/${PartOfSet;}${track;$_=sprintf("%02d",$_)} ${Artist;} - ${Title;}.%e' .
```
```sh
exiftool -r -P -ext flac \
 '-filename<~/Music/${Artist;} (${Date;DateFmt("%Y")}) ${Album;} [LL]/${TrackNumber;$_=sprintf("%02d",$_)} ${Artist;} - ${Title;}.%e' \
 '-filename<~/Music/${Artist;} (${Date;DateFmt("%Y")}) ${Album;} [LL]/${Discnumber;}${TrackNumber;$_=sprintf("%02d",$_)} ${Artist;} - ${Title;}.%e' \
 '-filename<~/Music/${AlbumArtist;} (${Date;DateFmt("%Y")}) ${Album;} [LL]/${TrackNumber;$_=sprintf("%02d",$_)} ${Artist;} - ${Title;}.%e' \
 '-filename<~/Music/${AlbumArtist;} (${Date;DateFmt("%Y")}) ${Album;} [LL]/${Discnumber;}${TrackNumber;$_=sprintf("%02d",$_)} ${Artist;} - ${Title;}.%e' .
```
### Copy directory structure
`rsync -av -f"+ */" -f"- *" ~/Music_FLAC/ ~/Music/`

### Convert all FLAC files into MP3 preserving directory structure and metadata, scaling cover art. Runs across all CPU cores. Run in parent folder!
`fd -t f -e flac -x ffmpeg -i "{}" -c:v mjpeg -vf scale=600:600 -q:a 0 -map_metadata 0 -id3v2_version 3 "~/Music/{.}.mp3"`

### Convert all FLAC files into MP3 preserving metadata, scaling cover art. Runs across all CPU cores. Run in parent folder!
`find . -type f -name "*.flac" -exec bash -c 'NAME="{}" && ffmpeg -i "$NAME" -c:v mjpeg -vf scale=600:600 -q:a 0 -map_metadata 0 -id3v2_version 3 "${NAME/.flac/.mp3}"' \;`

### 2 pass reencode all MKV in subdirectories to MP4 480p 512MB per hour, do not overwrite existing files.
`find . -type f -name '*.mkv' -exec bash -c 'ffmpeg -y -i "$1" -pix_fmt yuv420p -tune film -vf scale=-8:480 -c:v libx264 -preset:v veryslow -b:v 980k -pass 1 -an -f mp4 -map_metadata -1 /dev/null && ffmpeg -i "$1" -pix_fmt yuv420p -tune film -vf scale=-8:480 -c:v libx264 -preset:v veryslow -b:v 980k -pass 2 -af aresample=async=1:min_hard_comp=0.100000:first_pts=0 -c:a aac -b:a 128k -ac 2 -f mp4 -map_metadata -1 ~/Movies_Portable/"${1%.mkv}"-480p.mp4' - '{}' \;`

### Reencode all MKV in directory to MP4 in parent directory for playback LG SmartShare TV. Overwriting existing.
`find . -type f -name '*.mkv' -exec bash -c 'ffmpeg -y -i "$1" -c:v libx264 -tune animation -pix_fmt yuv420p -strict strict -profile:v high -af aresample=async=1:min_hard_comp=0.100000:first_pts=0 -c:a aac -ac 2 -f mp4 -map_metadata -1 "../${1%.mkv}".mp4' - '{}' \;`

### Reencode all MP4 in directory, scale to 1920 wide, film preset
`find . -type f -name '*.mp4' -exec bash -c 'ffmpeg -y -i "$1" -c:v libx264 -vf scale=1920:-8 -tune film -pix_fmt yuv420p -strict strict -profile:v high -af aresample=async=1:min_hard_comp=0.100000:first_pts=0 -c:a aac -ac 2 -f mp4 -map_metadata -1 "${1%.mp4}"NEW.mp4' - '{}' \;`

### Make thumbnails of MKV files
`find . -type f -name '*.mkv' -exec bash -c 'ffmpegthumbnailer -i "$1" -o "${1%.mkv}".jpg -s0 -m' - '{}' \;`

### Max compression settings for 7z
`7z a file.7z -mx9 -mmt 2 -md1024m files_to_compress`

### Strip unnecessary metadata from mp4 files - change mp4 to required extension as appropriate
`find . -type f -name '*.mp4' -exec bash -c 'ffmpeg -y -i "$1" -map_metadata -1 -c copy "${1%.mp4}"new.mp4 && mv -v "${1%.mp4}"new.mp4 "$1"' - '{}' \; `
