(latest debug CVS)
In Return to Zork, during the mine cart ride, the video blanks out a lot and the first few lines are appear corrupt. The sequence works, it's just a bit distracting.

The game also sends lots and lots of calls to the CD-ROM drive, presumably to keep it alive since the game uses CDA extensively, but there is still a lot of waiting on the CD-ROM drive when playing a new track. Would it be possible to add a mount option to limit in software the speed of the CD drive to prevent lots of spin-up/spin-down when fetching data and then fetching audio streams?

Yes, it’s my fault.

Regarding the cd-rom spin times problem:

Why don't you just make an .iso image and use it from a virtual drive?

CD/DVD-ROM access is still slow compared to hard-disk.

I understand that, but the problems caused here are not due to slow disc access but due to the latency in spinning the CD up to fast data read speed and then back down to 1x for the CDA read. Just something I noticed. 😀

Yes, it’s my fault.
