It is the summer of TMNT, and here is another Behind the Code video for the first entry on the NES. This video focuses on the application of gravity with respect to frame rate for jumping in the game and also breaks down the frame timing for making the three types of jumps – short, […]
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 […]
