I'm not sure if there are any remaining problems in 6888x emulation. I am thinking about what could be tested, but most things have been tested through Douglas' great test utility and some things have been tested by Toni separately.
I think 68040 might be incorrect for some conditions, especially related to nonmaskable overflow and underflow exceptions (inexact bit set, where it shouldn't). But it that makes more sense to test and fix that while adding 68040 arithmetic exception handling.
So what is next? We need a SoftFloat routine to convert between extended precision and packed decimal floats! This is commonly used, but quite faulty with native floats. Any ideas?
