I'm following along the complete beginner's tutorial at:
http://www.woodmann.com/crackz/Tutorials/Muadib1.htm
using BDASM and Hex Workshop. In the first example, where you are instructed to commend out a call:
e842000000 call 00401314
with NOOPs (0x90), I end up with a program that crashes. Re-evaluating it under BDASM shows:
9090909090 5 dup (90)
Rather than the expected NOOP instructions. I've succesfully completed some other examples on the page, where you change out maybe 2 bytes of hex, rather than 5. What's my problem? I'm sure it's something simple I'm overlooking, but have tried multiple variations of changes, all with no success.
Thanks!
