DS: I think most emulators have a 'maximum speed' feature, really...

Should be obvious when observing the sophistication of both BlueMSX and OpenMSX.

Note that, since I started using emulation, I began with NLMSX and used only that for years.

Just 1 or 2 months ago, I started using Blue for accuracy check regarding development, amongst other advantages.

But I have to say and can speak only for myself: since I was used to NLMSX and used it for everything, the transition to different emus didn't go quite 'naturally' since they are pretty different.

And that's why I don't know about any features, special stuff whatsoever.

I'm happy I know how to work .dsk's and .rom's with it already.
