So, in summary, to get this snapshot up and running:

1. Prepare your rootfs. Get a USB drive that you don't mind completely erasing. In my config, I didn't have a partition table. I just ran dd if=rootfs.ext2 of=/dev/X (replace X with your USB device).
2. Copy bootloader and bootloader script (ensure that the config inside is correct) to a place on your calc.
3. Connect your OTG cable's A end into your calculator.
4. Run the boot script.
5. Wait until the console reads "Waiting 10 seconds...". As soon as this happens, plug in your USB drive. A lot of text should scroll by - if not, you probably didn't do step 3 correctly.
6. Wait a little and you should eventually be dumped to a shell. If you get a kernel panic, it probably means you didn't do it fast enough or your USB isn't supported by the kernel.

To get mplayer working:

1. Plug in a USB drive with the movie/video you want to play and mount it as usual. This snapshot has support for MSDOS FAT and VFAT filesystems.
2. Run mplayer -vo fbdev2 -nosound -framedrop [filename]

This snapshot also has a non-working X server. If you can get xcalc or xterm to run, please email me!

Have fun!
