Punch-Out!! has been on my list of games to investigate for a long time, and I finally have something to show after a crazy amount of research. This video covers how opponent data is used to determine where to branch and what to do in code, how to manipulate boxer behavior, secrets that you will […]
Saturn-wizard, XL2 and crew (Corvusdeux & Ponut) have stunned the fan community with a tech demo that many would have thought to completely impossible… ‘IRRÉEL’ features the first two levels of the 1998 benchmark PC game, UNREAL, painstakingly & meticulously recreated in all of their gritty, late 90’s glory… Remade from the ground up, using […]
In December of 2019 after many years of runs, the speedrunning record for Castlevania on the NES was close to 11 minutes 24 seconds. In Summer of 2020, speedrunners took a new discovery for the implementation of scrolling for the game and used it to skip several screens at a time in various places throughout […]
RetroRGB gets down to business when it comes to measuring lag. That new wireless controller or fancy display might seem cool on paper, but what about performance? Modern devices and emulation of retro games can add to lag, but lag begins with the game code itself. Let’s hop into the execution time for standing attack […]
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 […]
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 […]
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 […]

The AMOS and STOS are forms of BASIC (Beginner’s All-purpose Symbolic Instruction Code) which is a programming language made simple for beginners to pick up and start their programming careers. This new version AMOS 2 is a […]
