I thought it would be fun to dig my nails into the code of Teenage Mutant Ninja Turtles for NES – a popular game that seems rather rushed. No surprises – the code is sloppy in more ways than one. Swimming, water current, that infamous Seaweed Screen of Doom, and some weird collision problems on […]
A viewer named Mike Schiraldi contacted me with a discovery he found in the code for Super Mario Bros. Apparently, there is a scrolling bug in the setup for the underground Warp Zones that involves a hidden enemy object! This video dives into how Super Mario Bros. levels are built, how scroll stops work, what […]
The latest video in the Behind the Code series features a look into the logic that drives Quick Man in Mega Man 2 for the NES. His behavior is a good example of code that somehow manages to work despite numerous bugs being present! I made a few code changes to correct these bugs and […]
The Talkin’ Code series of videos on Displaced Gamers is meant to be more casual (unscripted as much as possible) vs Behind the Code, and I used this episode to walk through what the code is doing during horizontal collision checks for Mega Man in MM2 along with some commentary. We also talk about performance […]
I’ve released a new video that focuses on the horizontal movement of Mega Man 2 and environmental collision detection. The game was coded in a way that allows Mega Man to move forward – but – constantly adjusts his position so he doesn’t end up stuck in a foreground tile. The problem is that this […]
If you are into NES games these days, you’ve probably heard the of term “mapper.” While the details of the various chips used in NES cartridges are just a quick Google search away, a few of their abilities were mentioned in Volume 20 of Nintendo Power back in 1991! I thought it might be fun […]
Hello, RetroRGB! Chris from Displaced Gamers here. I’ve released a new video that focuses on the basics of NES scrolling and uses Super Mario Bros. as an example. While doing research for this project, I found many new NES developers struggled a little bit when it came to understanding Nametables and Mirroring. This video makes […]
