The following patch will allow you to run Grand Slam Bridge from your hard disk without the key disk. 1) Install Grand Slam Bridge on your hard disk. 2) Copy CYBRON1.EXE to C.PGM. 3) DEBUG C.PGM u CS:8DB7 You should see the following instructions: CALL 8E08 CALL 8E33 INC CL CALL 8E08 CALL 8E33 ADD CL,2F CALL 8E08 CALL 8E33 INC CL CALL 8E08 CALL 8E33 You should change all the bytes from CS:8DB7 - CS:8DD5 to 90 (NOP). Thats all. If you have any comments or questions please leave me a msg Marty Kleiman. PS: This patch is dedicated to all those who have IBM compatable machines which wont run certain copy protected progams even though they own the original disk(s).
