Racing the Beam Explained - Atari 2600 CPU vs. CRT Television

The video is finally here! Thank you everyone for being patient for this one.
I hope you are ready for counting CPU cycles, cause there will be a lot of that in this video! The topic involves a lot of complex and confusing concepts, but hopefully the video makes it a bit more comprehensible. It was also difficult to not go off on too many tangents about the Atari hardware, so maybe there will be another video or series about it, because I think it'd be fun to talk about.
Please enjoy!

May Update

(Yes, I am allowed to make an update for May even though it is still April.)
Hi!
Things are coming along. The script for the next video is finally done. I'll be working hard to get that finished in the next week. It's been gnawing at me for the past couple months, and trust me, I want to see it done as much as you do. I've just been super busy with real-life commitments recently which has led to slow work. I almost decided to just take an extended break and turn off pledges for this month, but I realized it would be a bad financial decision, unfortunately.
Just in case you haven't heard, I recently bought a house, and have been spending the last month or so moving in and renovating a few rooms in it. Turns out owning a home takes a substantially higher amount of time and effort to keep up than renting a piece of junk, who knew? I've got a work station set up at least, so I can continue working on content, but until the house renovations are complete, I'm not gonna be back 100% just due to mental capacity of focusing on too much at once.
I do have some shorter video ideas in stock for once this one and the next one are out, so hopefully that will help a bit for the time being.
As always, thank you everyone for the support, and especially thank you to those who stick around even when the content output slows a bit. You're the best!
-Alex

SNES Features - Hardware Registers

The final part of the SNES Features series is here. This video is more of a reference than anything, so there's not much new stuff that isn't explained in any of the previous videos. I did realize that I never made part 6b on IRQ interrupts, so there will still be one more video before the series is actually complete.

February Update

Hi again! Update time.
The SNES Features pt. 11 video is in the process of being edited. I was hoping to have it done by the end of the month, but that deadline pounced on me pretty quickly (that's February for you). Should be out within a week, though.
I'm unsure of the timeline for the video after that though, because of real life things. I finally feel confident talking about what's been going on now that things are finalized. The past few months I've been working on purchasing a house--a friend of mine and I just finished closing on a place about a week ago. I'm moving there the week of March 21, and will probably be caught up in all sorts of things from then until the end of March or later. We'll see what actually ends up happening; I'll try not to have the video delayed too too much!
I really wanted to mention that here on my SubscribeStar page because this definitely wouldn't have been possible without all the help from everyone. All of my subscribers in particular for the direct support, but also all of my subscribers on YouTube and viewers for allowing the channel to grow where it is today. I'm super thankful that I'm able to support myself doing something I like and making stuff that so many people enjoy. Here's hoping the channel continues to succeed and grow even more so I can do some things I've been wanted to do for a while now (merch?), and make me feel a bit more confident in this large life decision!
Thank you again, everyone!
-Alex

Atari's Quadrascan Explained


Let's journey into the land of vector graphics, where pixels are a completely foreign concept!
In this video, we look into how vector graphics are stored and drawn to the screen, specifically for Atari's Quadrascan arcade games, including Asteroids and Tempest.

January Update

Another short update:
Next video is about 75% complete and should be out by the end of the month. In the last update I mentioned how I was going to be able to start off this year with a bang--this might be delayed just a bit... I've had a lot of stuff to take care of in real life that takes priority over everything. Luckily though once everything is said and done, productivity should go way up; I'll be able to share what's going on at a later point. I'm trying my best to still work on things between all the action, but I still feel a little bad not having finished anything since early November. Hopefully I can change that soon though!
Thanks for your support even during this lull period!

Update time! Gonna keep this one short.
I currently have four videos planned out. I have started writing the script for one (which I was hoping to have done this week, but read on to see where /that/ is going). I wasn't able to get much done this week due to holidays and other hobbies taking over a bit.
Well, now I'm sure to get the scripts done for all four of those videos soon, since my computer's power supply has bit the dust, and a replacement won't be in until next Friday. So for the next two weeks I'll be working just on research, planning, and writing those scripts. This means the video that was meant to be out by this weekend probably won't be done until near the end of the month unfortunately.
However, I do have to thank everyone who supports the channel, not only patrons on Patreon, but subscribers on SubscribeStar and all the viewers on YouTube. Because of you, I don't have to think twice about ordering replacement parts! Unfortunately the particular power supply I wanted to upgrade to wasn't in stock anywhere with quick shipping, it's still going to be a couple weeks before I can get back to work, but I'll make do with what I can until then.
Sorry again for another delay in video production--this year in particular has been pretty difficult. With a completed video and three other completed scripts going into the new year, it'll surely start off well, and hopefully I can continue that productivity moving forward.
Thank you!

5 Colors in One Sprite Explained

This episode of AVFX looks into how NES sprites can be faked to have more than 4 colors. It also mentions how sprite priority works and how game developers had to deal with rotating object indices to make them flicker instead of disappear entirely. I would have gone into even more detail about hardware limitations regarding the number of objects per scanline, but I didn't want this video to get too long!

Assembly Tutorial Poll

Assembly tutorials have always been a planned set of videos on the channel. When I make them, which direction would you prefer them to focus on?
Generic Assembly tutorials would probably use a faux instruction set that could be applied to a broader set of assembly languages out there.
SNES specific tutorials would go more in detail, and would also include interfacing with the SNES hardware.
SNES is the only option because that is what I am way more comfortable with. I could do NES as well, but I think there are plenty of good resources on NES stuff already. SNES not so much.

SubscribeStar doesn't support polls yet I don't think, so you'll have to vote somewhere else, like on Twitter: https://twitter.com/RetroGameMechEx/status/1320451588373315584

Data Redundancy Errors Explained

In this video we take a look at some software design patterns and see how they can cause glitches if they aren't implemented robustly. Specifically we'll look at item bag overflow in the generation I Pokémon games and cloning in Super Mario 64 as examples.
(The footnote at 10:40 is still a work in progress, so it won't be available until later today or tomorrow.)

New! Creator's Commentary

Hi there!
The next video is finally complete and will be available in the next few days. Starting with this video, I'd like to do a creator's commentary livestream where I watch the video back while talking a bit more about it, whether it be stuff I left out, more info, troubles I had while editing, etc. I'd also like to be able to take questions from viewers. I'm scheduling this video's creator's commentary stream for Wednesday October 7 at 5pm eastern (9pm GMT). I'll make another post here about 15-30 minutes before it starts.
This livestream will only be available for supporters to watch, at any pledge level. The broadcast video will be saved of course, and all supporters will be able to go back and watch afterwards if you can't make it to the live showing.
Hope you have a great conclusion to your weekend!
-Alex

September Update

Hi!

Just gonna make this quick and try not to sugarcoat anything, heh. Things have been really slow lately for a couple reasons. The first is that the ending of August and the start of September was really stressful for me and I just didn't have the motivation to work on anything. The second is that since just over a week ago I have been working on a completely separate freelance opportunity, which I have been putting 100% of my focus on. Therefore, the video I was hoping to release at the start of this month is still only about half finished. I'm just about done wrapping up with this job, feeling refreshed, so I should be able to return back to work on the channel next week.
Thanks for understanding, and I will try my best to get the video done before the end of the month.
-Alex
