Micro64 and unstable opcodes

I used the SHY-based raster syncing method (see Groepaz' "No more secrets" doc). Everything works as expected on Hoxs and Vice, but on micro64 (build 718) the timing is off. Does micro64 correctly emulate these unstable opcodes?

I´m an old friend of Bero and don´t believe he will not work on the C64 emulator any further if there is some important space for improvements.

If you can describe the timing problem in detail I can forward it to him.

He is aware of it, and he himself told me that he wont work on it anytime soon.
