Separate NMOS 6502 and CMOS 65C02 support CPU flag handling improvement NMI support Apple II (original model) support Apple II/IIPlus mode font improvement "M" glyph improvement Small _M14 / CLK_6502 fix. Reset behavior improvement Small monochrome video improvement - mono text now honors color selection just like mono graphics.
