Help Me - CRC Check and FileSize Check

[bunion]

Hmm i had same problem with a dll.....i can browse the resources, disassemble it etc but whenever i patch it although it still runs its faulty..my guess is that theres a CRC check somewhere .i dont have a clue where to begin looking for the check BUT i found a program thats in beta that says it can compare both files original and patched and then patch original keeping the same CRC its called

Theres also a toot by same author

CRC and how to Reverse it
_http://biw.rult.at/tuts/crctut1.htm

When i used it to compare the 2 files it says theres an overflow between offset and filesize..maybe im putting in the wrong offsets ...dunno

if someone can suss out the toot OR how to use the program correctly please let me know ok
