machine/at28c64b: read overflow initializing nvram (MAMETesters 08524) ( #12594 )
...
* Actual rom size may be less than AT28C64B_DATA_BYTES. a2bus/booti, as a motivating example, has a ROM size of 0x2000.

Fix a copy-paste error with the last fix for terracren, and updated the notes and filters to now correctly describe the two amplifier circuits. Added a note that this circuit needs to be converted to a netlist to be accurate due to the unusual hookup, and added a boost factor to the SSG channels to temporarily work around that fact.

Add protection against biquad filters producing aliased output or other noise if the stream sample rate is below the cutoff of the filter. Converted to use logmacro.h and added some additional optional log messages. Fix some incorrect calculations for the MFB band-pass filter parameters. [Lord Nightmare]

i386.cpp: correct errors in pentops.hxx caused by bad mmxprolog routine
...
Currently the mmxprolog routine can raise a #NM exception.
But the caller will execute the mmx opcode anyway, unfortunately
by fetching the bytes from the first instruction in the exception
service routine.
This adds a bool return value to mmxprolog so the caller can return too
without making a mess.
