I added Redstone to Minecraft in Minecraft!

After making full colour Minecraft in Minecraft on my redstone computer, the biggest request was to add redstone to it
So I did exactly that.

My redstone computer (IRIS) does not use any command blocks or datapacks and is fully functional in vanilla Minecraft.
The colour screen uses retextured redstone dust which gives me 16 different colours to use by changing the signal strength.

Watch my previous Minecraft in Minecraft video to see the non-redstone parts:    • I made full color Minecraft in Minecr...  

New Redstone Features:
Functional redstone dust
Functional redstone torches
Functional repeaters
Functional redstone lamps
Interactable levers
Redstone mechanics mimic vanilla minecraft
Repeaters and torches take 1 redstone tick to toggle
Runs 1 redstone tick per frame (the game is played at 6 fps)
The 3d models of the redstone components are made using flat 2d textures in a "+" shape

This program was written entirely in assembly.
The raw code ended up being over 7500 lines long,
but it barely managed to fit in the 2000 lines of IRIS program ROM thanks to my code optimiser tools.

Please note that the IRIS footage seen in this video has had it's speed increased to make it watchable.
It was recorded on a MCHPRS server running at ~270,000 times default redstone speed - then the resulting 80 hour footage was condensed down to ~8 minutes by speeding the video up by another ~623 times.
Overall that is a ~170,000,000 times speed up over the default 10 ticks per second redstone speed.

Note that speeding it up to be watchable does not change any of the redstone mechanics.
IRIS can be ran at the default 10 ticks per second speed - but the same footage would take ~4 years to play.
