Hi!
I also have issues with bone stock A4000/040 (only addon is Indivision AGA for now). Actually Cannon Fodder crashes in mission 24 so I can't move on. It gives me "Access Fault" ($7008) error messages all the time . Also some demos had similar problems and crashes on exactly same spot if I rerun them. I also tried all kinds of commands (NOCACHE, different max transfer values, etc.) and even tried OCS chipset on early startup, but for now no luck. My A1200/030 works flawlessly with WHDLoad software.
I even tried CF-card from that A1200 but same software crashes in same spots. So if anyone got realistic solution or sane explanation I'm listening too.
