Known bugs are described here
 
25.07.14
--------
 
- no known bugs, core passes cpu-check
 
22.07.14
--------
- ABX doesn't work
 
06.07.14
--------
 
- no known bugs, core passes cpu-check
 
29.06.14-06.07.14
-----------------
 
- Multiple opcodes fail: direct, extended opcodes, jmp, inc, dec, daa
  sex, long branches, indirect indexed opcodes don't load the indirect
  address
 
07.02.14
--------
 
- no known bugs
 
06.01.14
--------
 
- no known bugs
 
05.01.14
--------
- The bit instruction modifies the destination (it shouldn't)
- The E flag is not read back when RTI is processed. This means that FIRQ will not return
  correctly.
 
 
01.01.14
--------
- SYNC doesn't work as expected
- The E flag is not read back when RTI is processed. This means that FIRQ will not return
  correctly.
 
31.12.13
--------
- CWAI, SYNC don't work as expected
- The E flag is not read back when RTI is processed. This means that FIRQ will not return
  correctly.
 
30.12.13
--------
- EXG doesn't work, the register file can only be written once in the WriteBack cycle.
- The E flag is not read back when RTI is processed. This means that FIRQ will not return
  correctly.
 
 
28.12.13
--------
 
- EXG doesn't work, the register file can only be written once in the WriteBack cycle.
- LEAX/LEAY do not modify the Z flag
- The E flag is not read back when RTI is processed. This means that FIRQ will not return
  correctly.
