Unprotect for Test Drive (IBM PC)


BE SURE TO BACKUP YOUR TEST DRIVE DISK BEFORE STARTING AND USE THE
BACK UP FOR THE UNPROTECT. THIS WAY IF SOMETHING GOES WRONG THEN YOU
ARE NOT OUT A GAME..........

First you should rename the file tdcga.exe to tdcga

C>rename tdcga.exe tdcga

Next Load tdcga into debug...

C>debug tdcga

Then Follow the sample debug session:

-e 70D6 : Edit the contents of address 70D6

XXXX:70D6 55. : Should appear
: If 55 does not appear.. press enter and
: quit immediately. This unprotect is not
: for your version of Test Drive.

Now type "31" then press the SPACE bar.

XXXX:70D6 55.31 56. : Should appear
: If 56 does not appear.. press enter and
: quit immediately.

Now type "C0" then press the SPACE bar.


XXXX:70D6 55.31 56.C0 : Should appear
XXXX:70D8 57. : If 57 does not appear.. press enter and
: quit immediately.

Now type "C3" then press the ENTER key.

Now write the new tdcga game back to the disk:

-w

Writing XXXX bytes

Then Quit Debug:

-q

Now it is time to rename tdcga back to tdcga.exe

C>ren tdcga tdcga.exe

Now try to run the new (Hopefully) unprotected version Of Test Drive

C>tdcga

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
