Total DOS Collection (TDC) release #13 converted to floppy images - 3/12/2018

I love TDC, but I want to run these games on real hardware! To facilitate this 
I wrote a quick and dirty script to tear through the collection and create disk
images for anything that would fit on a 720K or 1.44M floppy. 

I'm also big fan of Jean-François DEL NERO's HxC floppy emulator and will never
go back to using a real floppy. With his release of the HxC firmware for the 
STM32 based Gotek you can have a USB based HxC emulator for less than $40 and 
store 1000 floppy images on a single USB stick! 

I hope this helps you enjoy TDC on real hardware!  

How to use the HxC images:

If your hardware supports 360K/720K disks copy the DSKAxxxx.HFE images from the
DD/hfe directory to the root of your USB stick.

If your hardware supports 1.44M disks copy the HFE DSKAxxxx.HFE images from the
HD/hfe directory to the root of your USB stick.

Take a DOS boot disk in HFE format, name it DSKA0000.HFE and copy it to the
USB stick. This is VERY important! Even if you don't need a DOS boot disk you 
still need an image named DSKA0000.HFE on the USB stick. 

Finally copy the HXCSDFE.CFG file from the root of this archive. It's a stock
HxC config file setup for indexed mode on a Gotek flashed with HxC firmware. 

Now just insert the USB disk into your HxC flashed Gotek and enjoy!

How to use the disk images:

The disk images are stored in the img directories and named diskxxxx.img. 

Just use DD or whatever software you use to create real floppies and dump the
images on appropriately sized media. 

Details on how the images were created follows.

Directory Structure:

<year>/DD/img         - 720K disk images
<year>/DD/hfe         - HFE converted disk images
<year>/DD/errors      - Error logs 
<year>/DD/images.txt  - TDC filename to numbered image mapping

<year>/HD/img         - 1.44M disk images
<year>/HD/hfe         - HFE converted disk images
<year>/HD/errors      - Error logs
<year>/HD/images.txt  - TDC filename to numbered image mapping

<year>/DD1/           - If there were over 1000 images during the conversion 
<year>/HD1/             these directories contain the next thousand.

Disk Image Creation Process.

720K Images:

dd if=/dev/zero of=<imagename>.img bs=512 count=1440
losetup /dev/loop0 <imagename>.img
mkdosfs -F 12 /dev/loop0
mount /dev/loop0 /mnt -t msdos -o "fat=12"
unzip "<TDC Filename>.zip" -d /mnt
umount images/mnt
losetup -d /dev/loop0

1.44M Images:

dd if=/dev/zero of=<imagename>.img bs=512 count=2880
losetup /dev/loop0 <imagename>.img
mkdosfs -F 12 /dev/loop0
mount /dev/loop0 /mnt -t msdos -o "fat=12"
unzip "<TDC Filename>.zip" -d /mnt
umount images/mnt
losetup -d /dev/loop0
