Ok, so all the features in current ("Laurent's") WinUAE core, including
debugging ones, should already be supported also in the new version.

That's good, because then Douglas' BadMood should work with it.
Bad Mood is a good test-case for compatibility, debugging/profiling
and DSP <-> CPU timings.

This will be very interesting for testing Douglas' Quake II renderer
Falcon port/rewrite, as Quake (II) maps don't really fit into 14MB.

If the new core were in separate directory, it could be added right away
alongside current ones and selected at config time.  This would make
testing and fixing things easier now that it's in working shape.

Once it works as well or better than current WinUAE core, latter can be
removed.
