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.

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.

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.

204d5cc964 Extends JoystickMachine protocol to cover ColecoVision use case. 
Also thereby implements input on the ColecoVision, in theory at least. No input is being fed though, so...
