          LODERUNNER by BRODERBUND is a good game with a very
          interesting copy protection scheme. Since the program
          ignores and overwrites DOS, and uses only BIOS calls,
          debugging is difficult.
          
          Copies made with DISKCOPY won't work, and neither will most
          copying programs. (i.e. COPYIIPC, etc.)
          
          Enclosed is LODRUN.COM which will ZAP LODERUNNER copies and
          make them run the same as the original. In addition, ZAPPED
          copies can be freely copied using DISKCOPY. (What more can
          you ask for?)  To use LODRUN.COM, make a copy of LODERUNNER
          using DOS DISKCOPY, then run LODRUN.COM and follow the
          simple instructions.
          
          LODERUNNER cannot be installed on a fixed disk, since it is
          a non-DOS program. You must always boot [Ctrl-Alt-Del] with
          LODERUNNER in Drive A: in order to run it. You may discard
          LODRUN.COM after you have ZAPPED yourself a copy. LODRUN.COM
          also will work on your (God-Forbid) original. I don't know
          if there is more than one version of LODERUNNER out there,
          but if you have a different one, LODRUN.COM detects this and
          reports it to you. It will not damage incompatable versions.
          You can run LODRUN any number of times on the same disk,
          although there's no reason to do this.
          
          LODRUN.COM uses interrupt 13h for corrections to your
          LODERUNNER disk (The only way to do this easily). The "CD
          13" code is disguised to avoid triggering "Trojan Horse"
          detector programs. If you are suspicious, I suggest you
          either single-step LODRUN using DEBUG (It's a short
          program), or you use a PC without a fixed disk. LODRUN is
          NOT a "Trojan Horse", however.
          
          Enjoy... The war against the copy-protectors continues...
          and we're winning!
          
          As always, comments and feedback appreciated.
