Happy Pi day, everyone 😄
-
I remember when I realized that game console were just special-built computers and not just "magic game machines" - so cool
-
This video is going to blow up on Pi Day. 🥧
-
I would love to learn more about NMIs and graphics programming.
-
I love the fact that the NES is asking "What is 'Flop'?". Just a nice touch. Also, 1:00
-
Super cool! Loved, "do you even flop bro"
-
Great video. The use of visuals on this channel to explain assembly and binary operations are very helpful.

I'm Brazilian and I study computer engineering, your videos inspired me a lot and I'm more and more interested in programming with the 6502. I would love to learn more about NMIs and I'm already following your playlist on basic assembly!
-
This video deserves 1000x the views it currently has. Thank you sir. This was Great!
-
Man, never thought ill watch a 9min vid about PI in the NES, but how you explain it and how you put it graphically makes it very engaging. Thanks for this video even though i dont have any idea of it!

It's not entirely true that the nes lacks multiplication and division, but that it's limited. There are 4 bitwise opcodes, ROL, ROR, ASL, and LSR which you can use to shift the bits left and right which can be used to multiply and divide bytes by 2.

I sold my stack of Megaman NES carts around 8 years ago... You just hit me so hard in the feels with your stack.
-
A complex, daunting process explained in a very understandable and concise manner. The visuals are very smooth and helpful and your speech has a nice, relaxing cadence. Exceptional video, can't wait for more.

「あのー フロップは何ですか？」 "EVERYBODY DO THE FLOP!"
-
This is great stuff! Finally! A concrete, complete, and not too complex example of how to get an NES to do some actual work! <3
-
This is really cool. I'm loving your recent videos.
-
Wow, I was once assigned to do this using the 8086 assembly and didn't even try, was too hard back then but definitely knowing that algorithm would have changed a lot
-
Great vid, awesome production quality and a super interesting subject all explained very well!
-
I've been living in Japan and learning assembly for the past 8 months now, but I was very surprised to see your NES speak in Japanese xD
