@The_Ultra-Mind what core are you using?

@Togepi trolling the DOSBox forum? From looking at your other post I would say yes.

It's still core=simple, but when it was auto, it made no difference.

Normal core at 3000 cycles seems to be right with my copy from the collection CD.

Don't forget to look for the hack if you want to complete Ultima II.

It doesn't seem right to me. Check this out. I left notes in the video's description.
I'd compare it to another YouTube video that's authentic, but I don't think there is one, since everyone seems to run it for the PC in DB and all the videos I've seen so far have the same issues.

I've tried both the floppy and cdrom versions of Ultima IV, and 1000 cycles seems okay for the animation speed and sound effects.

I am not that familiar with the game to say what it was originally like. I was just not seeing anything obviously wrong. There are retro hardware fans here that may have a better idea of what it was like on a real DOS machine.

It occurs to me that in 1985, U4 may not have been designed w/pipelined or superscalar CPUs in mind. That said, I see there's a cputype setting for the conf file, but why not for the 286? According to the status, the 286 is emulated.

~1000 cycles is a reasonable approximation of the speed of PCs when Ultima IV was released. The game was ported to PC in 1987 from what I have read, and the 386 was established by that time, if not exactly prevalent.

Later generation x86 CPUs handle the instructions of earlier generations quite well for the most part, and specific support for 286 as a cputype setting has not been needed for games. The 8086/8088 has some instructions and behaviors that weren't carried over into later generations, but there are very few games that rely on those. It's best to stick with the default cputype=auto setting unless there is some need for a particular type.

Well, I've set cpu=auto, cputype=386_slow, and cycles=fixed 500. The animation seems right, but the moon phases definitely change too fast and the spell casting sounds weird, but maybe I'm too influenced by how it sounded on the Apple. Oh well.

You'll never, ever get it to sound like the Apple out of the box: sound hardware was different and I believe Ultima 4 only supports PC speaker.
