lifning / AFS_Unpk.c
Last active April 23, 2022 09:49
an ancient (ca. 2005) sega dreamcast AFS archive unpacker written by a high schooler who still commented every line of their programs
#include <stdlib.h>
#include <stdio.h>
#include <stdint.h>
#include <string.h>
struct afsHeader // Header of the file
{
char magic[4]; // Magic word "AFS"
uint32_t count; // Number of .ADX files in the archive
};

Created February 15, 2013 19:48
A backup script I wrote as a system administration course assignment in 2011.
#!/bin/bash
set -e
# print usage information if -h flag is passed
usage()
{
cat 1>&2 <<EOF
usage: $0 [-hv] [-i instance] [-m method] [-t tag] -d dir
-h Print a usage statement and exit.
-v Be verbose.

lifning / glc-stream-and-record.sh
Created June 16, 2012 07:32
An attempt at a streaming-and-recording GLC script that doesn't work.
#!/bin/bash
mkfifo fifo.{glc,yuv,wav} fifosound.glc
glc-capture -o - -s $* | tee -a fifosound.glc > fifo.glc &
ffmpeg -i fifo.yuv -i fifo.wav -o recording.mkv &
glc-play fifosound.glc -a 1 -t -o fifo.wav &
glc-play fifo.glc -y 1 -t -o - | tee -a fifo.yuv | yuv4mpeg_to_v4l2 /dev/video1

lifning / glc-stream.sh
Created June 16, 2012 01:42
Used in conjunction with glc and v4l2loopback, this can stream games.
#!/bin/bash
mkfifo fifo.glc
glc-capture -o fifo.glc -s "${@}" &
glc-play fifo.glc -y 1 -t -o - | yuv4mpeg_to_v4l2 /dev/video1
rm -f fifo.glc
