Interesting, in fact it's very close to modern MCU architecture, except very limited IRQ resource and probably doesn't support nested IRQ at all. Modern MCU usually also come with NMI IRQ, but I found it hardly being used, because there are many other high priority IRQ available. I wonder what's the scenario of NMI in 6502.

Wow, such a thorough and clean explanation of how the CPU works. Animation really helps to understand what happens and why. Thank you! Looking forward to watching the next part.

I want to get into soldering and this might be my first project.

I am hypersensitive to input lag. I can't stand it. Anything above 4 or 5 ms messes with me. I'm so stoked that there are options like this.

Thanks. This video one very best overview of software emulation vs FPGAs I have watched on YT.

Really enjoyed this! Not a huge fan of the games on these consoles but I have a huge soft spot for the 6502

A bigger screen and I'd be in like Flynn.

the memories of playing flinger twister to input code comes flooding back

What's the software shown at 2:26 mark?

Great great great video. Thanks !!!

Maybe it sounds stupid, but it was only after you mentioned that the RAMs were labeled U1 and U4 that I realized that each chip in the Famicom had a label. It seems like it is something very obvious, because not even Rodrigo Copetti's book mentions it. I appreciate that you try to be so didactic, so that all types of audiences understand you. Excellent video!

Love this. Keep 'em coming. Thank you.

I'd forgotten how bad retro games look on LCD's without scanlines activated, the pixels look so unrefined and low detailed.

Is that the 8-bit guy's place? :D looks sooo similar!

Ken, when I see you've dropped a video I know I'm in for a treat!!!

So... if the Famicom 2A03 chip has 16 bits wide address bus does it mean that it really is a 16-bit CPU? (hello Atari Jaguar!) 😎

This is a great video to watch while I'm working on my NES emulator project! Thanks!

What I love is that the lack of hardware BCD is why Tetris eventually crashes. It's the software BCD that winds up eventually taking too long to calculate and results in corruption. So that whole Tetris crash thing made something this old relevant again. Also, I love that it's the same chip with that line cut, and that was enough back then to say it was a different chip. That's the only reason it was left out. It allowed the copy to be legal.

Great stuff!

the nes inner working was explained by many, i think someone should give love to the other consoles. you did an excellent job though when you said go make something cool i went and fill the icecube tray in my fridge. does it count?

Just stumble to your content regarding to Famicom design, thats a well made video... There will be mamy years agead on youtube for this channel for sure

These videos are awesome! My favourite lecture was Microprocessors in college, we've studied similar 8-bit CPU desings. Keep going Ken!

There's something I've been trying to remember about 6502 bus requests for a while and not into all the resarch and it's really the key issue I have with the 6502. The SNES has 128KB of working ram. People think it's all available. But it's not. I'm also quite proud of myself for predicting two 8KB buffers in the NES by counting the numbers and not figuring out how it could have 2K of work and video and also 8K, but slower.

I've really enjoyed your deep dives into the Famicom so far. Looking forward to the next one.

This isn't "begging the question."

Since the Z-80 was and still is today the most used processor in the world (enbedded today), I don't understand why people in the USA are so fixated on the 6502. Good video.

fantastic video !

The secret of nes is that aside from good games program..it can be bought by all unlike today only rich kids can have the PS5 😂

14:15 i'm sorry for being this immature but i'm laughing over how if you pause the video, and advance frame by frame you can get it to look like "good cock" instead of "good luck" because of how it rotates

one of the best videos about emulators/FPGA I can also say as a newly proud owner of a MISTer FPGA i can say the system it is the closest thing for casual retro fans like me. Some people say the differences about the lags in software emulators are not very big. For me they were too big since i grew up with nes snes and co. so i know perfectly how the should behave. When you know what you want then MISTer FPGA is definetly worth the money.

Thanks very much for the valuable information I would like to ask about the next episode

Great video thanks for the fun great time spent 😊

Is China spying with that hidden mic? 😯

The NES had a TV switch too. It was just unplugging the video line.

The famicom was my first console ever!! I have a special love for it!! 🥰🥰🥰

I worked at FAO Schwartz in Dallas and we got very little work done playing the Super Mario Bros. Game we had in our demo.

Dendy!

So the NES has RP chips (raspberry)? Just kidding 😂

Great video, excellent! I would like to ask about the cross-pad, is it of good quality? Doesn't it break easily? Thank you very much for the info.

It is incredible how much we are going backwards in content on "video" ... in 20 years we will see people studying "the sum", instead of studying more and more complex topics... year after year

AV Famicon never had component AV, the one it packed is called composite AV. Component AV has 5 wires/rcas.

I just ordered an Analogue Pocket today, mainly to have my Amiga 500 childhood memories in my pocket. And this great video supports my decision. Thanks!

Hello friend, to play with the SNAC on the Atari2600 with the paddles, do you have to power it with 5v?

Just like the UK black rubber keyed model, I really love the aesthetics of the Timex 1500.

1st time on your channel, great video. New subscriber from Argentina!

11:30 its composite video, not component
