Video: NES Programming #8 – Fixing Negative Velocity And Adding A Title Screen (NES misc)

Michael Chiaramonte shows us once again how to do some NES Programming.

In this episode, we fixed the ship physics so that the negative velocities are properly capped. We ran into a strange issue that ended up taking a lot of time to fix in the beginning of the stream, but then moved onto loading the title screen using simple run-length encoding. As I mentioned on the stream, if you’re interested in watching me work on the tools that we’ll be using for tile loading, compression, etc. let me know in the comments. I was originally thinking that I’d simply focus on 6502 assembly but if people are interested in watching me work on the tools too I’m happy to do so.

Video: NES Programming #7 – Finishing Up Ship Physics And Added Game State Transitions (NES misc)

Michael Chiaramonte shows us once again how to do some NES Programming.

In this action-packed episode, I cleaned up most of our ship’s physics and capped the maximum velocity in the positive direction. I have to revisit the negative direction. I then added the ability to deal with game state transitions, but found that that introduced some undesired behavior. After getting it working, it’s still unclear why jumping directly to the beginning of the game loop is causing it to process the game states incorrectly and I’ll revisit that in the next episode, along with assets for the title screen.
