We can debate how likely that would be (I > personally like the idea of watching BA, and just ensuring the screen > is on), but it's a valid corner case. He covers that with a timeout after an entire frame of reads. The odds that the timeout will occur at the same time as the code decides to switch to writing is going to be low but theoretically possible. Which is why I threw in the ultimax + nmi + irq as another option. I don't know what a program that has no screen output, has nmi asserted constantly, has irq masked and is only performing reads for an entire frame would actually be doing.Received on 2018-06-22 10:00:04
