Unprotect Chessmaster version 1.21   by Independent (IND)

Chessmaster version 1.21 issues a call for the name of the purchaser. With this patch, you will be able to change the name and the serial number (using Norton) to anything you want ie: serial # 000000 John Q. Public etc. You will then be able to make copies. Using Norton; search (hex mode) CM.EXE for the following: 50 e8 1e 46 83 c4 02 0b c0 74 04 NOP all so that it now looks like this: 90 90 90 90 90 90 90 90 90 90 90 After this, search for the name of the owner (text mode). In this area you will also find the serial #, street address, state, etc. Change all this data.
