Is there a way to turn off crc check in Olly?
Like pressing "R" and write "faults off" in Softice?

IN DEBUGGING OPTIONS-EXCEPTIONS youa have the possibility of OLLY don't stop in diferent exceptions listed and non listed too, with the option ADD NEW EXCEPTION.

I have reversed a program called Musarc that I had on an old CD. It expired november 1997. But it has a crc check that dosent alow changing of the code. It will just stop working. In softice it can be fixed with the faults off command I read in a softise tutorial. But I can't get softice to work on my w2000.

If your on W2K, couldn't you place a hardware read breakpoint on the code you modify so you can spot who is doing the CRC and NOP it?
