THere's also a slightly strange palette choice, though Exxos will like it as it make s a pink Mac in to top right corner.
Aha! Maybe I should add an Exxos mode where everything are shades of pink

P.S. The way I make the disk access speed fast is to increase the MacOS disk cache to its maximum, which is just over 7MB. With the standard 32K the disk speed is about a third of that of the Mac Classic.
Oh, great tip! I'm going to try that here too

Well, both the LC475 and LC630 ROMs work fine with the LC630 "feeling" a bit faster.
However, the benchmarks show that this latest revision is a bit slower again in ST-HIGH mode (native):
The main interrupt handler has definitely kept growing and that'll have an impact on performance.
One of these days I'll need to make an optimisation pass, there are quite a few things that can be done.
It may also be overly aggressive in regards to cache flushes at the moment, and context switches could be cheaper in some cases.
Sometimes it's also hard to know for sure when it actually gets slower, or when Speedometer gets more accurate
The current versions video emulation may be slower than the previous one in cases where a lot of screen is changed, but faster when less is.
Exactly where the threshold is is hard to say and will also depend on the difference in speed of fastram vs st-ram (that difference is huge on my computer, but I'd imagine it's less on a TT)
