65816 Assembly Tutorial: Loops @pweingar

Tail Recursive Part two of my series of tutorial on 65816 assembly language. In this tutorial, we cover looping by setting up and displaying a simple sprite. This is unfortunately a rather long video. I couldn't quite figure out how to separate it into smaller ones. I'll try to keep subsequent videos a bit more digestible.

Two corrections:
1) Around 8:21, I said that C is set if the accumulator is less than the operand. I misspoke there: C is cleared if the accumulator is less than the operand. It is set if the accumulator is greater than or equal to the operand.
2) Around 43:33, I said that BASIC hex numbers start with the "at" sign, I meant to say the "ampersand".

Assembly Tutorial 6 Indirection

Tail Recursive 2022-07-12 | This is probably going to be the final video in the 65816 assembly tutorial series. I might continue making tutorials, but they would more likely focus on the C256 specifically. Unless something comes up that I've missed, I believe that these videos have pretty much covered the basics of assembly with the 65816.

As usual, the code can be found on GitHub: github.com/pweingar/65816Assembly

This video is pretty long, so I'm going to set up chapter markers in it so you can skip to the parts you'd like to see. Much of the video is the code walk through, which may or may not be helpful.

65816 Assembly: Interrupts

Tail Recursive 2022-06-02 | After a year's hiatus working on the portable operating system for the Foenix machines, I'm turning my attention again to the 65815 assembly tutorials. This time: what interrupts are, and how they work.

65816 Assembly Tutorial: The Basics

Tail Recursive 2020-12-14 | In honor of Stefany Allaire announcing the C256 Foenix U, I have finally recorded the first in a long-planned series of tutorial videos about 65816 assembly language.

As always your questions and comments are always appreciated. I'll try to incorporate any feedback into the next videos.

Memories of Nexus: Housing Walkthrough

Tail Recursive 2018-10-08 | With Wildstar shutting down soon, I wanted to record some of the better features of the game before it goes away. One of those features is player housing. In this video, I explore a large player made build I found the other day. This is a long video, as I did not want to chop it up too much, so feel free to fast forward.
