Can confirm that the tnt does work
A computer built in minecraft with redstone running minecraft...
in minecraft!
Full colour Minecraft in Minecraft running on my redstone computer IRIS has been a dream of mine.
I have been working on this program for over 4 months. I hope it is worth the wait!
After I made DOOM run on IRIS, I knew Minecraft would be possible too.
IRIS is a fully programmable 16 bit redstone computer.
Meaning IRIS is capable of running even more games and programs than this!
Subscribe for future videos of IRIS running even more cool stuff!
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.
Minecraft Program Features:
- 8x8x8 block world
- Unrestricted 3d movement and camera rotation
- Jumping and gravity
- Placing and breaking blocks
- Animated breaking and placing
- 11 types of blocks
- 11 types of items
- Functional hotbar and inventory
- Crafting system with both 2x2 and 3x3 grids supported
- Inventory supports moving stacks, merging stacks and moving single items
- Item quantities are displayed in binary (due to screen resolution being too low for full size numbers)
- 90 degree FOV
The 2048 Instruction limit on IRIS is why I had to get creative to add the "functional TNT". I would have added even more features such as ores and the furnace but the instruction limit prevented me.

![MPU 7 Bubble Sort [ 2 Hz Minecraft Redstone CPU ]
The MPU 7 is my latest and fastest Minecraft Redstone CPU.
This video is at 4x speed and the carpet mod tick speed is set to 2 times speed.
Here the MPU 7 is sorting a reversed list of 15 numbers using parallel bubble sort. It is able to bubble up to seven numbers at the same time which makes the program run a lot faster.
Ignoring the time taken to initialise the RAM and print to the display - it took 556 cycles to sort the 15 values (4 minutes and 38 seconds)
Also I didnt realise the blinking cursor was broken until after I finished recording it and I didnt fancy recording it again. Thats why the cursor is missing.

MPU 7 Specs:
• No command blocks or pistons
• 2 Hz clock speed (5 ticks or 0.5 seconds per clock pulse)
• 5 stage waterfall pipeline (Fetch1 - Fetch2 - Decode - Execute - Writeback)
• 10 general purpose simulated dual read registers (with no read before write hazards because of the automatic forwarding)
• 8 bit word length
• 256 word instruction ROM x2
• 32 bit instruction length (that includes an 8 bit immediate value)
• VLIW architecture
• 32 bit hardware BCD converter
• 8 bit hardware multiplier
• 8 bit hardware divider
• 8 bit RNG
• 64x32 pixel display (1x1 pixels) which can be shifted upwards 8 pixels whenever needed
• 1 frame buffer
• Full qwerty keyboard with arrow keys and function keys for user input
• 128 bytes of main RAM
• 256 bytes of screen RAM
• Up to 128 I/O ports
• External 8 kiB paging ROM for storing large amounts of data (Like Bad Apple!!)
• 7 testable flags
• Full 7 bit character set (a custom one, so not ASCII) which uses 4x8 characters
• Can be started, stopped and reset from the UI
• Almost fully compatible with URCL
