   Encrypting Lynx ROMs using the Atari tools:
       By: Carl Forhan (forhan@yahoo.com)

*NOTE*  These programs were designed for an Amiga computer.

1. All tools run on an Amiga (my Amiga 2000HD dev system from Beyond
   Games works fine for this).

2. Unzip the files and transfer them to your Amiga computer. You can
   probably run from floppy as well, but I have not tried this.

3. Follow the instructions in "README2.TXT", which will tell you to
   format a spare floppy named "RSA" and to run the command
   "EXECUTE DOIT" against your unencrypted game ROM. Do both of these.

4. Bring up a second command line shell window.

5. When prompted to take the disk to the "encryption system", don't hit
   return yet. Simply remove the "temporary" RSA disk, and execute
   "REALBIG" (which is found in the "rsa1" folder, in the C directory).
   Follow the instructions, and insert the RSA disk as prompted.
   3 blocks will be encrypted during this step.

6. When you are prompted for the "next disk to encrypt", go back to your
   first command window. The temp RSA disk should still be inserted at
   this time. Hit return at the prompt, which will bring up another
   message saying to go back to the "encyrption system" and perform the
   rest of the encryption.

7. Bring up your second window again, and hit return as prompted.
   5 blocks will be encrypted during this step.

8. When you are prompted for the "next disk to encrypt", go back to your
   first command window, and press return. (You don't need the second
   window any longer, even though it is waiting for the "next disk"
   still.)

9. Your input ROM is now encrypted (the original file has been altered).
   Have fun using this ROM on a *REAL LYNX*! :-)
