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

Thomas Harte	87760297fc	Fixes underpumping of SN76489. ... Audio works now. Though I still need properly to confirm who owns dividers in practice. I think probably all division should be within the SN.	2018-02-27 22:59:29 -05:00
