Hi! Unfortunately LiteShare is out of service and the torrent contains the file with music at the end. Can somebody share the fixed version again? Maybe @puste still has it?

ffmpeg -i "$1" -i "$2" -codec:v copy -codec:a aac -filter_complex '[0:a][1:a]join=inputs=2:channel_layout=quad:map=0.0-FL|0.1-FR|1.0-BL|1.1-BR[a]' -map 0:v -map '[a]' "$3"

The video file goes in $1, the estim audio in $2 and the output file in $3. This creates 4.0 audio channels with the original ...

A really great tease! I only found some minor bugs:

Spoiler: show

- Two instruction pages in round four don't appear at all: round402c and round403.
- The "EDGE" button on pages where you're told to edge/hold it doesn't really make sense.
