Hi All, The only problem I've been having with my Games is a very "rare occasional" Type 1 Error, which is a Bus Error at FFCA7634_stSearchTab+00284 while reading long word from 696E6974 in Supervisor data space. Actually, I've had two of these spaced three days apart and after many reboots for various reasons; yet the Macsbug data produced is IDENTICAL. I have made a number of changes to the program in the mean time. I am assuming, at this point, that it is a ROM Bug? and not a problem with MY/FB Code. Is this logical and what do the PROS out there think should be done about it. The occurence has maybe been once in 50 or more plays of the game. Is this something I "should/have to" live with or can it be fixed? I have not been able to associate it with any specific activity. Macsbug indicates that it is in the ROM at _stSearchTab+00284... The disassembly indicates this at that point: *MOVE.L A0,-$0220(A6) |2D48 Just prior to this was a JSR ([SetUpStretch]) |4EBO I appreciate ANYONE'S help/input on this. Joe Wilkins
