WHDLoad on a 68040

[Vulpine]

I'm having trouble with some games through WHDLoad on an A4000 with a 68040. Generally it manifests as slowdown as soon as more than a few sprites appear on screen; in Cannon Fodder, for instance, playing with four soldiers is impossible as the game becomes unbearably slow as soon as they all start firing. Putty Squad is generally too sluggish to be enjoyable.

I've tried a couple of tricks such as setting the NOCACHE and NOMMU tooltypes, to no avail. Is there anything else I should try, short of going back to an 030?

I also had a 68040 in my Amiga 4000. The 68040 has more issues when running WHDLoad games. Sometimes the game is very fast or very slow. Other processors like 680x0 are more compatible than the 68040.

Before you swap the 68040 for a 68030, Do you have set the transfer mask to 00x1fe00 in HDToolbox?

I have not yet tried that (the transfer mask) -- is it safe to do?

The '040 sometimes requires a little more fine-tuning than an '030, but other expansions in the system can also cause issues (for example a network card, graphics card, or USB card that may need additional scripting to disable prior to starting the game.  WHDLoad includes some basic scripts for these).

The WHDLoad website has a complete list of tooltypes, but off the top of my head one that has worked well for me in the past is NOAUTOVEC.  

Thanks for the advice. I don't have any Zorro or graphics cards installed, so I'll try tweaking the tooltypes and see if I can massage it into behaving. I'd love to stick with the 040 because it's so much noticeably faster than my 030 otherwise!

Still no real change with those tool types or the HDToolbox change. Does anyone have a suggested list of tool types for Cannon Fodder specifically?
