customnmi.s debugging

[VakarisZ]

Hey. I forked this project in attempt to alter it into a RToF project here.
I had some success, but results still deviate ~100 CC's (20 000 packets gathered). I think the biggest delay happens on ESP "bouncer" (receive packet -> send it back routine). Could this routine be improved by writing a custom NMI? Or is sending a packet too long of a process for NMI? Maybe I could set a value with custom nmi and then send a packet on hardware timer if this value is set?

I am not really sure... I did try it once, but my biggest problem looked to be stability of the crystal sources. https://www.youtube.com/watch?v=RSQK5w6LMSc

I don't recall jitter being an issue.
