Alfonzo’s Arctic Adventure v2018.04.27 (WIP) (NES Game)

The author of Alfonzo’s Arctic Adventure got a tiny update for us!

Release notes:

Just finished up designing the 40th level in Alfonzo. I’m planning for 96. 24 of those levels were made within the last 2 months, with 8 done in the past week. I feel like I’m hitting a nice groove here.

Video: NES Programming #24 – Interrupting The Interrupter (NES misc)

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

NES Programming #24 – Interrupting the interrupter

Watch this video on YouTube.

Quote:

In this episode I got the MMC3 IRQ working once I realized the I had to re-enable interrupts on the CPU. After that, we saw what happened as you mess with the nametables while scrolling and experimented with one solution to vertical scrolling and scanline counting. I need to some more research to see how other games do this. Thanks for watching and see you next stream!

Video: NES Programming #23 – Sprite 0 and MMC3 (NES misc)

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

NES Programming #23 – Sprite 0 and MMC3

This week we figured out why the sprite 0 code was slowing things down for the game when there were lots of entities on screen and then we figured out how to change the game to run with mapper MMC3. I wasn’t able to get the scanline interrupts working properly yet but we’ll get that handled on Thursday. Thanks to those who watched!

Video: NES Programming #22 – Oh, I guess I missed that word (NES misc)

I continued working on getting sprite 0 hit detection working. And it did finally work, but I couldn’t get it to scroll vertically after sprite 0 hit is triggered. I learned today that apparently you can’t do that like you can with the horizontal scroll. Need to research about that some more. Update: I have researched this and have a solution. Requires some optimization though

Video: NES Programming #21 – I’m the map, I’m the map… (NES misc)

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

NES Programming #21 – I'm the map, I'm the map…

Watch this video on YouTube.

After being off for a week we did some small optimizations, messed with how levels are loaded, and then played around with sprite 0 hit detection. It was a pretty fun stream because I was mostly messing around with the NES code and not the asset tool. I need to get map building working properly in the NES asset tool so we can get more serious about building backgrounds. I also need to figure out the sprite 0 hit detection better (or, you know, just figure it out)

Alfonzo’s Arctic Adventure v2018.04.19 (WIP) (NES Game)

The author of Alfonzo’s Arctic Adventure brought another update to our attention.

Release notes:

New level clear animation! I’m pretty proud of how nicely that spiral effect turned out. Had to use some creative math to get it to work with the scrolling, but definitely worth it. #nesdev #nes #indiedev #gamedev
