   |                                                                        |
   |  Information seems to be leaking out about this one so we decided to   |
   |  make a public release to avoid "fixed" firmware that may not be so    |
   |  friendly to the precious yamaha 400.                                  |
   |                                                                        |
   |  Well, the rumors are true. This does work, we now have 8 of these     |
   |  units, and all of them can now read GD's                              |
   |                                                                        |
   |  This is not the original way that we began ripping GD's. we have an   |
   |  actual serial link setup that our hardware engineers figured out.     |
   |  This method of ripping is much more efficient as you may imagine      |
   |  we have known about this method for 3 weeks now but have chosen to    |
   |  keep it secret to protect Sega and the various developers that        |
   |  are licsenced by sega.                                                |
   |                                                                        |
   |  To date, Dreamcast Iso's are only available mostly to those with      |
   |  high speed internet access, or other connections.                     |
   |                                                                        |
   |  This will soon all change and only patches will need to be released   |
   |  to make self ripped games playable.                                   |
   |                                                                        |
   |  We hope that Sega and it's developers are up the the challenge that   |
   |  sony has been facing with the PSX. Sony has realized that the scene   |
   |  could help them and they used it to their advantage                   |
   |                                                                        |
   |                 "Adversity Brings Greatness"                           |
   |                                                                        |
   |   Directions                                                           |

   |                                                                        |
   |      The utility's filename is dld_dos.exe.  The utility               |
   |      takes four command-line parameters:                               |
   |                                                                        |
   |                                                                        |
   |   1) The flash file.  For this parameter, use                          |
   |      the scsicom.bin file path.                                        |
   |   2) The SCSI ID of the GD Writer to be reflashed.                     |
   |   3) The ASPI ID of the SCSI card on which the GD                      |
   |      Writer resides.  This is a zero-based index                       |
   |      to the card.                                                      |
   |   4) The value 11000.					            |
   |      For example:						            |
   |      dld_dos.exe scsicom.bin 5 0 11000                                 |
   |      will reflash the GD Writer on ASPI ID #0, on		            |
   |      SCSI ID #5.                                                      |
   |                                                                        |
