Thomas Harte	9e0a56b4f0	Withdraws the 2600 from .rom consideration. ... Will return when it is performing more sanity checks; for the time being I don't want it constantly forcing multimachines.	2018-03-07 16:21:17 -05:00

Thomas Harte	74dfe56d2b	Expands documentation of NMI setting. ... Given that it was previously incorrect, explains logic behind request_status_ and last_request_status_ setting. Also takes the opportunity to ensure that NMI is 'sampled' at the same time as IRQ; whether the next thing should be the NMI routine now occurs one cycle before the end of any instruction. That's an assumption for now. Testing to come.	2018-03-02 11:10:02 -05:00
