edit: nvm, figured it all out eventually.
The wiki says that using DTEC you can copy the photon's ctype into a block of adjacent FILT. I have no idea what they mean by adjacent. What are the specific requirements for this. I have fired plenty of photons into DTEC and nothing has happened.
here. id:1686349 it uses BRAY instead of PHOT but the principle is the same
You are a champion.
I was thinking about how to manage address selection while in bed last night. Saw this tutorial and it's pretty much what I was thinking.
So FILT works the same with BRAY too? Interesting.
edit: I only want the spark to pass through if it's an exact match, not just containing a bit that matches the address. Any ideas?
edit2: problem solved. XOR + inverter works perfectly. How did I miss this.
