Responding to myself responding to myself:

I borrowed the KERNAL, Basic, and Char ROMs from a VICE installation, after which the updated #Ultimate64 booted up as expected. I can’t say for sure whether all issues are gone, but Mayhem in Monsterland, which would never load successfully with #JiffyDOS earlier on this machine started up like nothing; and Gunship, which would inevitably crash at an arbitrary point in loading, has come right up into flight mode. Awesome!

Experimenting with #JiffyDOS on my #Ultimate64 - it seems to be pretty hit-or-miss. The webpage had a note recommending what seems to be CIA timing settings:

> Can I utilize JiffyDOS on the Ultimate II?
>
> Yes. Customers have noted that settings PH1=140 and PH2=80 work well.

I don’t see any way of finding nor tuning these settings, though. Have I misunderstood something?

Bought some #JiffyDOS chips for various hardware. These come with toggle switches to switch them out. Instead of drilling a hole in my case(s) for that, I'm thinking of cutting a rectangular window and putting a DIP switch block there and just wiring to the first one, for future switch use (bigger eproms, etc). Is this a good idea, or are the little DIP packages not suitable for that purpose for some reason I haven't divined?
