INDYCAR RACER TWO BYTE CRACK

Cracker          : ENUS

Crack            : REMOVED DOC CHECK

Date             : 21 NOVEMBER - 1993

Dedicate         : MACRO NIT   GETAWAY   GOD DENMARK

What it is

This crack removes the doc check, so the program will accept any input,
even a simple return will do.
I have playtested it for an hour, and didn't find any strange thing going
on, but if you do, please leave a msg. on Getaway.

How to install

Just unzip all the files into the program directory and run PATCHER,
or PATCHER /R to undo/reverse the crack.

Cracking Notes

Nexus USA who released this game at 11 november wrote this:
Yeah...This is one of the greatest car racing game i've ever seen...
This may look strange but we couldn't make a 'usual' crack for it,
but it's too good to wait more... So we included all the passwords,
you really ALWAYS can answer the query with the included textfile.
The difficulty wasn't in the protection itself but in the envi-
ronment : this game,at the moment when i write these words,is really
IMPOSSIBLE to debug...We tried all the existing debugging programs
but none of them worked. Now the challenge is there,who will be the
1st to release a real byte crack for this game...? I guess a new
debug utility should permit it really soon. We really don't like
such way to proceed, but this time there was no other way.
As some other group don't crack their wares also, i guess this is
cool, as you really can play the game once you printed the textfile.
So do it now, print INDYCAR.DOC included in the 3 disks.
Anyway, we'll release a crack patch as soon as it'll be possible.

It has now been 10 days, and no crack have turned up, so I decided to
try myself. There is at least one debugger? that can handle programs
that uses DOS4GW from Rational Systems, but since the extender was
binded to the exe file, you have to know what you are doing?.
Now inside the program and debugging, the program steals the keyboard
interrupt, and thats not good, since the doc check is keyboard input
only. The only thing to do?.
Now it's possible to get to the doc check with the keyboard intact,
but it isn't a easy crack, remember the good old Sierra and Lucas
games, where the program ran in one big loop and called the same routines
(something like in Windows)?
But if one look long enough in a rational manner, one will finally
find a place? to make a clean! (I hope) crack.
If you can answer yes to all the questions, you! could have done the
crack yourself.

This waw my crack no 124.
