Amazing Videos. You revived an old hobby of mine as I followed along with the VIC 20 series, and you're inspiring me to come along again! Thank you!

Looking forward for the next videos in series. !! This is brilliant

Interesting approach.  I've been working on a hand-wired discrete logic homebrew composite video card, and was toying with how I might want to approach sprites.  Your method ends up being a bit different from how I'd approach it, but yours is also targeting an established feature set of a common machine, one that has to do alot more.  Nice work, this is fascinating.

Nice work..
I have been recreating arcade machine hardware for a few years but the cost of buying chips now is ridiculous. What I have ended up with is using 3 or 4 pi pico boards.... one emulates a processor,  1 does sound, 1 generates VGA.... works very well and I wrote all the code myself. The added bonus is it has the memory space to include 4 or 5 games all with very different arcitectures (6502/Z80) ... sprites were a chalenge but works a treat now 😂

I’m so appreciative of your videos. To take time to share your knowledge like this is such a selfless act. Thank you.

Great Video Matt.The You tube algorithm just suggested your video, and I am very impressed with your knowledge. I subscribed immediately. Looking forward to watching some more videos, I was a user of the C64 and the Atari 800XL in the 1980s, and I am nostalgic about that period.

geez... it's amazing to me that human beings exist that really understand this as thoroughly as you do. in my mind, literally miraculous.

Great video. Thank you!

I Love this series. Thank you!

1:38 It's the MIBs, uh, here come the MIBs, uh, yeah

Amazing stuff!

I love Commodore 64 ❤❤❤

fantastic!!

Subscribed.  I've been wanting to build a mature computer from scratch with common generic logic chips.

Great video, I never knew that 4-7 steal cpu cycles.  looking forward to your next video!

I look forward to your exposition of the X position register.

Ooh, I wonder how close your work must look to the original prototypes used to produce the integrated chips. There's some photos of the per-integratiion prototypes for Amiga chips floating around the internet - interesting stuff.

I'm really enjoying this video series, it's really interesting to follow. I've only gotten as far as the intro so maybe this is elaborated on later, but I just wanted to mention that the sprite collision registers are virtually useless and extremely few games make use of them. You can't mask which particular sprites they should trigger on, so in your example with Pac-Man they would cause a never ending stream of interrupts as the ghosts collide with each other. Also, from a game design perspective you rarely want pixel perfect detection as it just feels unfair.

Fantastic stuff! 🎉 Thank you so much! ❤

what a project - a discrete sprite engine ! WOW Amazing !! I dont want to know how many hours runs into that project....
